Unable to connect with WPA active in Vista

    Question

  • Dear all,

    I Have managed to install my wireless card in vista using the XP drivers, and when all is up and running it does detect my wireless router it just will not connect. If i enter the incorrect WEP code Vista tells me that it was incorrect, but when I use the correct one a message appears telling me that Vista was "unable to connect due to a timeout".

    If i disable WPA security on the router it connects no problem.

     

    Any help would be wonderfull

  • Cable router is the only option, which is what im on now, but i've given up on vista, upgraded my computer and performance is just still nowhere near as good as XP so thats what ill be sticking with for now!

     

    Just out of interest though, what is the manufacturer of your Wireless adapter and router?

  • Have you tried setting it to WEP instead of WPA security? I have mine set to WEP and it connects. Though I had the broadcasting turned off and it wouldn't connect at all for some reason.

  • My router is set to WPA or WEP security and i have tried every combination available in the properties, although i have just realised the properties I am changing are for a wireless connection i set up manually whilst trying different things to get it to work (in vein) which appears when i goto "Re-order Wireless networks", whereas the connection that is available in the Connect to window is the one automatically detected with the default name and not the one i gave whilst manually attempting the connection.

    I Have no problem connecting with xp on the same machine using the same hardware and never have.

  • snap :( , I have exactly the same problem.

     

    when I boot xp the WPA works fine but not in VISTA and the only way to connect is drop back to unsecured

    not really very good protection wise!

  • I am running Vista RC1 (5600) on my laptop and am experiencing the same behavior -- attempting to connect to a wireless network using WPA-Personal with AES encryption fails with a timeout. I am using the correct authentication type and key because if I provide incorrect information, I get a different error saying as much.

    I can connect to unsecured wireless networks without issue.

    When looking at informational events from the new Diagnostic Framework, I see that the "root problem" as determined by the tool is in Layer 2, "mulitcast keys not generated before the timeout."

    Does anyone know what is causing this behavior, and if there is a solution or workaround?

    Thanks in advace!

  • try to change the encryption type on your router or access point from AES to TKIP. That worked for me. somehow vista doesn't support AES encryption under WPA1. however it does work perfectly under winxp.
    Friday, October 06, 2006 8:10 PM
  • I upgraded to the newest publicly available build (5700) and now the wireless works with WPA using AES. I did determine that the driver for my wireless card (an Intel Pro/Wireless 2100) listed on Windows Update as an optional download broke this functionality. Reverting back to the original driver installed with Vista corrected this issue for me.  I hope this helps someone else.

    Friday, October 06, 2006 8:28 PM
  • Just curious...while you've got your network connection working now, have you tried connecting to another Vista installation locally? We've got two Vista systems running RC2 (now), and while they each work fine over wireless with WPA to the wired network and beyond, they can't connect to each other. Other wireless systems (running XP) on the net have no trouble with either Vista installation, but the two Vistas just can't see each other. The problem goes away when we switch back to WEP, so we're pretty sure there's some bug in the WPA portion of the wireless stack.

    Since this is RC2, we're a little concerned. I'll have to check whether reverting to the base driver changes the behaviour.

    Sunday, October 08, 2006 2:43 AM
  • Where did you get the 5700 build from? I have not seen any mention of it on the download site and would like to try it to see if I can get my laptop to connect to my WPA enabled router.
    Monday, October 09, 2006 2:52 PM
  • I got the same informational event with RC2: "Layer 2 security key exchange did not generate multicast keys before timeout".

    Someone knows what it means?  I'm using WPA only security (TKIP) and I'm use I'm close to have a functional wireless...

    I need your help guys!

  • I still have this problem on Vista  build 6000 (MSDN release). Using no encryption or WEP works, but as soon as I switch to WPA I get the timeout.

    I've got a 3COM wireless ADSL modem/router. The computer is a HP nw8440 laptop with a Intel Wiress card build-in. Any news on this issue?

    Same story, Works fine with WEP, doesn't work with WPA. I know the key is right because it tells me when the key is wrong. This happens for both 802.11g and 802.11a networks I use, both with WPA.

  • I'm having exactly the same problem with an Intel 3945ABG wireless card in a new Toshiba laptop running Vista Home Premium. Trying to connect to a 3Com router with WPA enabled.

    It will connect with either encryption disabled or WEP encryption but neither of these are ideal! I've installed the latest driver from the Intel site, but still having the same issue...anyone have any ideas?
    Wednesday, January 31, 2007 9:24 AM
  • Just to also add I am having the same problem, also with a 3Com router, vista just refuses to connect in WPA, however using WEP I have no problem. Whilst using XP I can connect in WPA no worries which leads me to believe it is Vista. I am running the recently released Vista Ultimate. I had the same problems in beta but expected that they would be fixed!

    Any advice is greatly appreciated.

    Intel has released updated drivers for the Intel(R) PRO/Wireless 3945ABG Network Connection. I downloaded the drivers, 10.6.0.1_VT_130279.zip, version 10.6.0.46, unzipped them and ran DPInst32.exe as an Administrator (Right click > Run as Administrator). I then ran iProDifX.exe as an Administrator. I can now connect to my WPA networks, both 802.11a and 802.11b/g.

    I also ran Windows Update taking the important and recommended updates.

    I suspect I did not need to run iProDifX.exe or run Windows Update to fix this issue. I suspect the new drivers fixed the problem.

    For the Intel(R) PRO/Wireless 3945ABG Network Connection, go to this page and select your OS. (In my case Windows Vista* Ultimate, 32-bit version)

    http://downloadcenter.intel.com/scripts-df-external/Product_Filter.aspx?ProductID=2259

    Here's the detailed information for the driver I'm using:

    Intel(R) PRO/Wireless 3945ABG Network Connection

    Driver Provider:  Intel

    Driver Date: 12/19/2006

    Driver Version:  10.6.0.46

    Note that the file name of the download looks like it matches the driver version, but it doesn't exactly, so don't go by the file name alone! You'd think that the drivers I had, 10.6.0.29 are more recent than those in a file named "10.6.0.1_VT_130279.zip". NOT SO! Think again! Since this driver package is bundled, it actually has two versions, with the 9.1.0.115 version being for a different hardware wireless adapter. Sheesh! Note their download Date shows 1/24/2007. I actually think they posted this just a few days ago because I've been checking. They took a while in QA - Since 12/19. Sure wish I had these earlier.

  • I have a new laptop with Vista Premium since yesterday. Connecting to my wireless LAN resulted in same problems as stated here. I also have an Intel(R) PRO/Wireless 3945ABG Network Connection. Installing the latest Intel driver did not resolve my problem; I can still not connect using WPA.

    Saturday, February 10, 2007 11:16 AM
  • Me too. Installed the drivers, went through all the steps described above and still have the same trouble...

    Saturday, February 10, 2007 9:37 PM
  • I'm not sure the problem is with the driver. I have a brand new Sony (Vista Home Premium) using an Atheros wireless lan chipset and have the same problem - timeout when trying to use *any* encryption but connects fine with no encryption. I've never experienced any problem with a variety of wireless nics and MS OSs (going back to Win98.)

    I've also upgraded the nic driver but the problem is still there. I'm starting to think it's a bug with Vista's WPA1 WPA implementation.

    Sunday, February 11, 2007 7:50 PM
  • I agree, I just bought a brand new HP DV9205 which comes loaded with Vista Ultimate.. I too am having the WPA issues, I've resorted to wep for now..  guess I might have to get a new router one of these days and get myself hitched up with WPA2

    T.
    Tuesday, February 13, 2007 10:15 AM
  • I'm also having this timeout problem with my Safecom PCI LAN adapter.  I'm beginning to wonder if it is a Vista incompatibility with my router, rather than my network card.  I'm trying to connect to a 3Com ADSL router, is anyone experiencing these timeout problems with a different brand of router?
    Wednesday, February 14, 2007 4:20 PM
  • I'm connecting to a NetGear WGU624. Using 802.11b/g or 802.11a gave the same results. It just wouldn't do WPA until I upgraded the driver and got lucky. Now it's working fine. I had no issues with my Buffalo router at homme using WEP. My cubicle mate said it just starting work for him at some point. Go figure! I'm convinced it's a Vista issue combined with the drivers regardless of the access point used.
    Wednesday, February 14, 2007 8:19 PM
  • It's certainly a confusing issue, I had to use the XP drivers with Vista to get the card detected and working, I've read reports from other users with the same card who had no problems connecting once they had the drivers installed, that's what made me wonder about the router possibly being a common link.

    Like all the other people having this trouble, I've had no problems whatsoever running this kit in XP, so hopefully it is a niggle in the new Vista network code or a compatibility problem with using the XP drivers, I'm certainly not willing to replace any of my wireless kit simply to run Vista.
    Thursday, February 15, 2007 8:28 AM
  • I'm using an Intel PRO/Wireless 3945ABG wireless card (built into the new notebook as standard) to connect to a D-Link 614+ - we all have different gear, I'm still led to believe it's vista disagreeing with WPA1..

    T.
    Thursday, February 15, 2007 10:46 AM
  • Vista and WPA1 certainly appears to be the only common factor here.  Unfortunately my router has no WPA2 support and I'm not willing to downgrade to WEP simply to use Vista so it looks like I'm stuck with XP until someone can come up with a proper fix.
    Friday, February 16, 2007 8:42 AM
  • I have the exact same problem.  Cant connect when using WPA on VISTA.

     

    Brand new HP dv9000 running Vista Home Premium.  Turn off encryption and it works.  Arghh!!!  I cant go back to XP

    Sunday, February 18, 2007 10:14 PM
  • Raider, what type of router are you using?
    Tuesday, February 20, 2007 11:52 AM
  • I'm using a 3Com Office Connect 3CRWDR100A-72 ADSL Wireless Router.

     

    Tuesday, February 20, 2007 6:59 PM
  • I'm also using a 3Com 3CRWDR100A-72, it's a solid router which has never let me down.  Vista simply refuses to connect to it; since the router only supports WPA1, I'm unable to try testing WPA2 to see if that helps.
    Wednesday, February 21, 2007 9:33 AM
  • Hi All

    I have had this problem for a while now also. I am running a Toshiba laptop with an Intel 3945ABG in WPA mode under Vista Enterprise.
    As per a previous response I have tried updating to the latest Intel drivers but still get the the same timeout error message.
    All works fine in XP and using Vista WEP just not WPA with TKIP.
    Again as mentioned it fails if i type a random password but times out using the correct one.

    I've also tried using an RALink2000 equivalent USB adapter with its latest Vista drivers, which shipped with the Ozenda router I have, but again get the timeout error so it seems unlikely to be driver related ???

    Looks like Vista has some WPA patching due <sigh>
    Wednesday, February 21, 2007 1:32 PM
  • Same problem

    HP dv8327ea - Intel Wireless - WPA - Router Philips (Belgacom)

     

    Friday, February 23, 2007 11:35 AM
  • I have a similiar issue - "Wireless authentication failed due to a timeout" when trying to connect to my WPA secured wireless at home using Vista Enterprise (RTM). Annoyingly, a Vista Ultimate (RC2) computer on the same network connects fine.

    Oddly enough, there are two other wireless networks I connect to on a regular basis using WPA1 without any problems.

    When I changed encryption from WEP to WPA I was able to get a connection, but as soon as my computer went to sleep I couldn't get to reconnect. I tried installing a later wireless driver, which again let me connect but as soon as my computer awoke from sleep it no longer connected.

    I tried rebooting my router, my laptop and even deleting the network connection but still no joy. I've tried rolling back the network driver, re-installing the latest network driver but still no joy.

    Friday, February 23, 2007 5:38 PM
  • Well, I'm not sure what has changed, but now I can reliably connect if I turn off the wireless switch on my laptop for a few seconds, then turn it back on again. Odd given previously a reboot wouldn't fix it and I could have sworn I'd tried this. I had previously connected via an ethernet cable to my router so I could at least do some internet work, but apart from that...

  • Same problem with a HP NC6000, Atheros Wireless card, and a Asus WL-500G router. It's driving me mad...

    Sunday, February 25, 2007 4:37 PM
  • ok here is my two cent to make everything cloudy :)

    there are three networks that i connect to, the home which is a wireless adsl rounter using wep, no problems connecting and staying connected.  a friends house which has a wireless access point setup to use wep that has an external adsl rounter. finally uni which i would say has the same type of setting as my friends house except that it has no security.

    both my friends place and uni i can not connect to, vista see that the network exists but when i try to connect it tells me that is a problem and when i check the event logs the following message appears

    Detailed root cause: 802.11 connection failed due to status code 1

    before going to vista, all three networks worked fine with xp.  i read in place to try to disable the ip6v protocol, this had no effect on the problem.  any suggestions?

  • i've got a somewhat similar issue.
    scientific atlanta webstar cable modem from cablevision
    dell laptop with vista home basic
    macbook osx

    it can connect locally, but the wireless router isn't connecting to the internet. when i hit diagnose, it says possible DNS issue.

  • I'm using a Belkin F5D7630 ADSL Router and it seems to connect no problem with my Acer laptop using WPA encryption with a build-in Intel 2200 B/G wireless card. Unfortunately my roommate's laptop, an HP Compaq nc 8430 which has an Intel 3945 a/b/g card, do not want to connect. Both work under XP, but under Vista only mine connects. I'm starting to think there might be compatibility issues with the Intel 3945 a/b/g card under Vista, since it seems most people with problems have one.
    Friday, March 02, 2007 5:44 PM
  • I am having the same problem connecting via an INTEL 3945AGB and a SIEMENS Router SX541. With no encryption at

    all it works fine, with WPA, no way ... maybe an observation from my side can help to locate the problem :

    When I set the laptop (TOSHIBA Satellite) to WPA and plug the machine to the router via wired Ethernet then

    the WPA connection is established, and when I unplug the cable, the WPA connection remains active as long as

    the machine runs. After a reboot, again no WPA connection ...! Someone having any idea around this strange behaviour `?

  • I found a solution!

    I am using an Intel(R) PRO/Wireless 3945ABG Network Connection in my notebook as well and had the same problems to estabilsh a WPA-PSK connection with my router.

    When I enabled IGMP v2 Multicast in the DHCP section of my router it worked!! Hurra

    Friday, March 16, 2007 9:11 PM
  • Where exactly you find that?

    my Belkin  F5D7630 router doesnt have that function :(

  • Solution for Linksys WRT150N Router That Worked 4 Me...


    Might work with other Linksys routers and perhaps other brands.

    On Security setup page, in the Internet filter section, uncheck "Filter Multicast".

    Simple as that. Vista's Network Event Error Log led me to this solution. Error logs almost always give you a clear idea of what you are up against, if you can interpret what u see.

    Good luck to all on solving this problem.

  • Hi,

    I had exactly the same problem with my new laptot that has Windows Vista on.

    I found two options to connect it successufully to the web:
     1)
    set the router to wep security only and the network security option in the
    computer to wep
    2)
    Set the router to wpa security only and the network security option in the
    computer to wpa-personal and  select  tkip instead of aes


    Basically, the new computer with Vista on, does not connect to the
    internet if the router has both wep and wpa
    security. If I choose only wep or only wpa (as long as I select tkip) it works.

    Tuesday, March 27, 2007 11:12 AM
  • it make no sence, ccoz the router can only enable one type of wireless scecurity I tried WEP it work, only WPA vista not accept and my router hae WPA-TKIP enable only still doesnt work... so damn annoying
    Tuesday, March 27, 2007 8:53 PM
  • I have had the same problem since purchasing a new HP with Vista Premium preloaded a couple of months ago. Intel 3945ABG card. Neither the 10.6 nor the recently posted 11.1 intel drivers fix this problem but looking at the widespread reporting of this issue, its clearly a Vista network stack bug. Such a pain- wireless (especialy secure wireless) is a necessity these days- how could they release an OS with it not working?
    Friday, April 06, 2007 10:26 AM
  • Do you think Microsofte notice this problem and will release some patches to fix it later on?
    Friday, April 06, 2007 11:36 AM
  •  

    Ditto -- new HP Notepad (Intel 3945ABG card) with Vista premium and I am unable to connect via WPA to my ISP's wireless mesh network.  If Microsoft and hardware vendors were intending to make this version of Vista more "user-friendly" they missed in a major way and ended up soaking us of $ in the process. 

     

    There is no easy fix for me without incurring additional costs to address what is clearly a Vista protocol stack issue.  Hopefully, some of those high paid Microsoft software designers and managers will read this and get off their keesters to give us a software fix in a future Vista release of software.  In the meantime, we're better off to stay on Window's XP where WPA worked just fine!

  • Switching to WPA2 worked fine for me.
    Tuesday, April 10, 2007 3:26 AM
  • Arvo All

    I've got the same problems using Vista with wireless WPA, Belkin router, Toshiba A100 2.16 ghz chip etc, specced up nicely thankyou 

     

    Finding it hard to pin down the problem as I have had the following scenarios:

    - connection to WEP good (interesting to see but you can't work securely on this setup)

    - connection to WPA failing - log points to multicast issue? - this is the most prevelant response

    - toshiba laptop not even identifying the existence of the wireless network!

    - laptop connecting successfully to WPA network (pretty random)

     

    All these scenarios are running in parallel to an older Dell D400 (running XP) which identifies and connects to same WPA network with few problems (though not 100%)

    I haven't been fiddling with the router or the settings on the laptops, these are just the things that have occurred over the last week.

    No answers here yet and the search "vista wireless problem wpa" googles for just over half a million hits and rising...

  • Yes, just purchased a brand-new Acer including Vista Ultimate and Intel 3945 ABG. After two evenings including upgrading to the newest 11.1.0.86 3945 ABG drivers the conclusion is that Vista Ultimate + Intel 3945 ABG + WPA-PSK does not work. Playing around with my WLAN AP, I experienced exactly the same things as reported in this thread. Only real good discovery is that ...

     

    WPA2-PSK (using AES) does work !

     

    Numrous XP computers have absolutely no trouble connecting to the WLAN AP by WPA-PSK but I have however noticed difficulties with the Intel WLAN chips before under XP.

     

    Forgot to mention that my AP is a Zyxel 1000G

  • ok, problem solved

    and it was simply an upgrade to the latest Belkin Firmware Update from the belkin website

    Very helpful Belkin helpdesk and website sorted this

    WPA works all day every day now and other options such as WPA2 are available

    experiencing no dropouts etc in either Vista machine or XP machine for last 5 days

     

    very happy

    cheers

  • could you tell me which belkin router do you have and which firmware you upgrade to?
    Saturday, April 21, 2007 8:09 PM
  • I agree its a Vista and WPApersonal issue (TKIC).

    I have Vista Home Premium, running on a Sony Vaio VGCLA2 (desktop based on laptop technology) with an Atheros LANexpress AS IEEE 802.11g PCI-E wireless adapter. Driver is updated to latest. The wireless router is a Philipps SNA6600 with latest firmware.

    I get an intermittent connection error - wireless drops out after sleep or screen saver with the timeout error if you try to re-connect immediately. It comes back after a while all on its own (meanwhile I have re inserted a cable connection). A laptop running XP connects beautifully with WPA TKIC.

    The frustrating thing is I can find no settings that seem to allow me to adjust the time of the timeout ! The event log provides no useful pointers.

     

    When using the same set up and WEP it worked fine. Conclusion: Vista and WPApersonal seem to be the common cause.

     

    Over to Microsoft methinks for a Vista patch.

  • looks like this card is just working with the older standard 802.11b and this one does just support wep. Then you are not able to connect to a wireless network using wpa.

  • I had this problem up until recently with the following configuration:

    Toshiba laptop

    Card: Intel 3945ABG

    OS: Vista Business

    Encryption: WPA1

    Router: 3Com 3CRWDR100A-72

     

    I just changed my router to a Netgear DG834G and the problem went away.

  • I am having the same problem as everyone else. I am trying to connect to my university's wireless network with my laptop, worked fine under XP but since installing vista i can detect the network and it asks me to input my user name and password, when i click ok the box just pops back up to enter user name etc. The network uses WPA with TKIP. Since this is the university network changewr router settings isnt an option for me. I am using a intel pro 2200bg wireless card and have installed the latest driver. Any ideas??

  • If you can get into your windows "manage wireless connection" one thing that Drove me nuts was seeing that windows was setting my wpa2  to enterprise wpa2. Id change it and then it would connect but to fix it I had to delete my connection from the list and use the Check for connections icon in the taskbar and run the setup. Now vista says "oh o.k" and lets me connect hassle free. Double check if that will help you.

  • Same issue here:
    Machine won't get a DHCP address.
    Using Intel 3945ABG - WPA2
    TrendNet TEW-631BRP.

    I had thought the issue was the router (Netgear) so I switched to trendnet.  But, since introducing another machine on the network with the 3945ABG card, whenever another machine with 3945ABG comes out of sleep or hibernate, it never get's an address assignment.

    Vista (all update istalled)
    Zyxel P-334

    Is somebody solve this problem? I can't connect to my router if I use WPA-PSK. WPA2-PSK, WEP work fine.

  • That 1st KB article is for an upgrade of XP to Vista.  I don't have an upgrade - I'm clean install on ALL affected machines.

     

    The 2nd is waking up from sleep.  My issues arise during normal operation.

     

    This is an Intel driver issue.  It's faulty.  From my event log i get 100's of the following errors indicating the device driver crashes and the stack is still trying to resurect it.  The NETw4v32.sys is the device driver file from Intel...

  • In my case I have error:

    Wireless authentication failed because of a timeout.


    Wednesday, May 16, 2007 1:15 PM
  • I have an intel wireless card with my new lenovo n100 3000. a,b,g,n draft. for the most mine not having any problems. Like I said try going into manage wireless connections ,clear out the router setting to connect to router if possible, and connect through the windows software(My Pc had a link in the task bar) tell it to search for connections  and go through the wizard. I was having problems connecting and that seemed to clear them up. 
    Has anyone tried this other than me ??

  • Intel has posted an updated driver (11.1.0.100) and I'm trying it now....


    Tuesday, May 22, 2007 11:08 AM
  • This one (new Intel drivers mentioned above) appears to be working for me tonight. I'll keep testing in case but so far, so good (fingers crossed)

     

    Smile

    Tuesday, May 22, 2007 9:00 PM
  • where do you download the intel drivers from?
    Tuesday, May 22, 2007 9:08 PM
  • I hate to jinx it, but so far so good and when it does drop, not requiring a reboot, just a hard switch off/on of the Wifi

    Cicorias,

    11.1.0.100

    glad it's working for you, I've installed and I'm now getting a worse connection. Tried rolling back and restoring check points however 'something' has changed and the connection is alot worse even with the old drivers. O' well I suppose it's good practice putting the vista install disk in the machine, again, again, again.... (if it wasn't for the vista media centre component I'd go back to xp, sigh !)

     

    Is the 'hard switch off/on of the wifi' actually on the laptop or on the router ?

    The reason I ask is the vista event logs are reporting DHCP errors with either timeouts or unable to renew the dhcp lease.

    Do you use DHCP ?

    If yes do you fix the mac on the scope ?

    What is your dhcp lease time ?

      

    this is frustrating.......

    Wednesday, May 23, 2007 8:27 AM
  • I use the "hard switch" on the laptop.  The reset stuff through Networking center never get's it.  In fact, if I start with that then the hard switch won't work either.

     

    I do use DHCP.  I did lower the roaming agressiveness to it's lowest setting.

     

    I have have Multicast Streams and UPnP enabled on the router.

     

    I have stepped back to WEP 128 bit mode and may in the future go back to WPA if I'm reasonably stable for the next week or so.

     

    DHCP lease time is 24 hours and set to always broadcast.  Not clear on what you mean by fix mac on the scope.  I'm not restricting based upon mac addresses.

     

     

    Wednesday, May 23, 2007 12:22 PM
  • lucky to some i even updated to the latest drivers from Intel all i get not is not time out notice, instead i am getting constant connect and disconnect from the intel card.

    My router is a Belkin F5D7630A router... there is not much setting in it.

    Are you using the same router and got it working under WPA personal encryptions?

    Thursday, May 24, 2007 10:29 PM
  • Well, It's back again for me too. I was able to get connectivity back with a off/on of the hardware WiFi switch a few times, but now required rebooting.

    Same issue, the NETw4v32 error never stops populating the event log.

    This driver is ***. I have several machines, Toshiba, Dell that all have the exact same issue on Vista. What poor quality. I was going to try to replace the card with an Atheros card, but on the Toshiba it requires way too much disassembly to get to the mini-pci card.
    Saturday, May 26, 2007 12:17 PM
  • There's an updated driver there now.  Trying now.

    11.1.1.11

     

    Saturday, May 26, 2007 2:24 PM
  • I have also tried that dirver version and still doing the same, with timeout message and such.

    I seriously think is the Vista Operating system clashes with the WPA encryption, since WPA is a replace of WEP before WPA2 being develop, my theory is they start to lose out the WPA since WPA2 is completed implemented, so now either intel or Vista not boring fixing this small issue with router only have WPA and WEP encryptions.
    Saturday, May 26, 2007 4:07 PM
  • I'm running WEP - happens with WPA or WEP.

     

    The failure is in NETw4v32.sys which is a device driver from Intel.  Chalk it up to bad QA by Intel and bad device driver code.  Something Microsoft can't control, but only influence. 

    Saturday, May 26, 2007 5:15 PM
  • yep. 11.1.1.11 also fails

    although I don't get the netw4v32.sys failures, mine are timeouts through either dhcp or authentications timeouts/issue, or sometimes it just works.......

     

    this thread starting on 16 June 06, nearly a year later and still problems. Wonder what the other posters did, new wifi card, new router, used wep, or got a long patch cable ?

    Saturday, May 26, 2007 6:12 PM
  • I've tried 3 routers: Belkin, Netgear, now TrendNet.

     

    I'm running WEP with same issues.  If the toshiba wasn't so hard to switch out the mini-pci I'd replace it; I'll be trying that on the dell with an atheros card (Gigabyte).

     

    Actually, when it fails, I put in an old Microsoft G PC Card for network access MN-700 I think.  It's a pain.

    Sunday, May 27, 2007 12:15 AM
  • With the latest 11.1.1.100 drivers, I now get a Error 121: "The semaphore timeout period has expired" (ERROR_SEM_TIMEOUT).

    I've rolled back to the inbox driver that came with Vista RTM. 

    My guess is, those on this thread in the past with no posting of current issues has rolled back to the inbox.
    Monday, May 28, 2007 12:25 PM
  • Is anyone using the ProSet software the Intel provides and any luck with it and the latest drivers?  I wonder if that's why some folks are no longer reporting issues.

    Another question, I'm potentially going to replace the 3945abg card, but I started down the path with a Toshiba M5 and it requires quite a bit of disassembly.  Any pointers on the level of disassembly?
    Monday, May 28, 2007 12:29 PM
  • I'm still having issues. I haven't seen anything in this thread yet that yields a stable WPA setup under Vista. I think many of the people you have not heard from on this thread are simlply enduring flaky wireless connections. Those who disagree with this statement, please post your solutions!  I certainly find it odd, with the bad behavior of these drivers that Intel, Microsoft, Dell and other hardware vendors have vague release notes that don't really mentions these common problems. They also aren't doing anything pro-actively to fix these issues or at least they are keeping a very low profile and still failing to solve the issues. As an indication, it's interesting to note how fast the Intel 11.1.1.11 drivers were released after the 11.1.0.100 drivers and they both have serious issues of dropping or disabling the wireless connections and they are no known issues or release notes that address these obvious issues. Grrr!

     

    I've had my best luck so far with the Intel 10.6.0.46 drivers. I've tried Dell 11.1.0.86, Intel 11.1.0.100, 11.1.1.11 and other versions.

     

    Currently, I'm trying to get the Intel 11.1.1.11 drivers to work reliably. Regardless of WEP or WPA encryption and network A or G  and wireless router (netgear or buffalo), I have the same problem that the Internet connection gets turned off. My laptop (Dell Precision Workstation M90 with Intel 3945ABG) has a green light that shows the WiFi is on. When the connection fails after a few hours, or minutes, the green light is off. It is on after rebooting. The adapter shows enabled, but it's quite clear that it has been powered down some how even though I'm on AC power and it's set to stay on. Once it's off, trying to access the network menu from the network Icon in the system tray takes minutes when it pops right up when the card is on.

     

    The serious problem with the Intel 11.1.1.11 drivers is that once the wireless network is turned off by the driver failure, the only I've found to get it turned on again is to restart the computer. Most Unsatisfactory!@

     

    I'm now experimenting with the Allow the computer to turn off this device to save power setting. Each test case can take hours since it fails after some minutes to hours and then you have to restart the machine. Otherwise I'd already have results for you! If I can't get the Intel 11.1.1.11 drivers working, I'll go back to the ones I've had the least serious issues with, the Intel 10.6.0.46 drivers. The Intel 10.6.0.46 still have unacceptable bugs, but I can sort of function with them by continuously re-connecting to the network. At least the 10.6.0.46 doesn't require a restart to restore the connection!!!

     

    Control Panel > Network and Sharing Center > Manage network connections

    Wireless Network Connection > Properties > Power Management
      Unselect Allow the computer to turn off this device to save power.

  • I still have problem this WPA-PSK connection timeout.

    Is anybody know howto launch Intel Wireless Proset connection utility in Vista?
    Tuesday, May 29, 2007 10:43 AM
  • I had the same problem with Windows XP but solved it installing the intel drivers AND connection utility. Now in Vista there isn't a good driver from Intel and I cannot find the custom Intel connection tool, so I can't connect to my router. I don't know if it's a driver issue or a vista fault but I can connect in XP and Ubuntu, but not in Vista.

    Using a Intel 3495 integrated wireless card (on a Sony Vaio FE31Z laptop) and a 3Com router.
    My router doesn't support wpa2 so that is not an option.

    The Intel 11.1.1.11 drivers are working for a bit over a day at home (802.11G WEP) and work (802.11G and 802.11a WPA) once I unselected (disabled) "Allow the computer to turn off this device to save power setting".

     

    Here's one way to find this setting under Windows Vista:

    Control Panel > Network and Sharing Center > Manage network connections

    Wireless Network Connection > Properties > Power Management
      Unselect Allow the computer to turn off this device to save power.

    Network connector Intel pro/wireless 3945ABG Driver 11.1.1.11 (also Acer uses eNET software, but ive disabled that for now)

     

    Ive spent hours trying to get it connected to my router with WPA PSK (Not WPA2)

    I have one laptop connected, somehow, and it seems stable (Took hours of fiddling, router firmware updates, laptop driver updates etc)

    But the exact same other laptop i cant connect i get this error (same for some other people i gather

    (Bit embarassing as im an IT tech guy, if im struggling, joe public aint got a hope!!!)

     

    EDIT:

    I need to add, ive taken the laptop to work and it connects perfectly first time, with no hassle no drops, to the wireless router, The router is also a 3Com 3crwe725075a.
    Now thats just darn fustrating, My problem MUST be the home router?

    I have exactly the same model lapop from acer 5630 with same Card

    How did you managed connect to the router with WPS-PSK for one of them, all i got still is constant connection timeout
    Monday, June 04, 2007 10:15 AM
  • hi mate,

    If i knew how i got it connected, id be able to connect the second one lol. Its not as if i a noob either, which is even more fustrating. (I am new to vista though)

    One tip i got from Acer support was disable the eNet service to stop acers wireless software and try using the microsoft service Wlan auto-config (make sure its started)

     

    Also they suggested turning off IPv6 as my router might not support it, (ill try that tonight)

    Monday, June 04, 2007 10:23 AM
  • Do Microsoft ever put help on these technets forums? If they do, why are they not commenting here?
    Monday, June 04, 2007 10:38 AM
  • update:

    Turning off eNet and IPv6 on my Acer 5630 didnt help

    Monday, June 04, 2007 2:12 PM
  • found the answer!!!

     

    Binned the 3Com router bought a Zyxel router £29 from amazon.  Worked like a dream and great range

    http://www.amazon.co.uk/ZyXEL-P660HW-54Mbps-Adapter-Bundle/dp/B000I1OA6G

     

    got three wifi's connected (inc 2 Acer aspire 5630's) and a LAN pc , all WPA-PSK

     

    dont waste your time, also comes with a USB wifi dongle, what a bargin!!

  • it's not really an ideal solution to solve problem to a IT guy like me, but when it comes to desperation, or exhausted out all possibilities then that may be a final solution
    Tuesday, June 05, 2007 10:52 PM
  • You know on a side note ive seen in the warm weather is that the intel wireless card in my pc tends to shut down in the heat of the day. It will be running and then all of a sudden loose connection and not find my wireless router.It got annoying enough i had to do wired connection. Ive ended up shutting down the computer and running the fan in my room. Nothing else is effected on pc except the wireless card.

    so could it be hardware as well giving problems.

    the main fix for future may be getting an cooler to go under neath my laptop to assist in this matter. The one store i checked had it for $30 US Dollars .
    Wednesday, June 06, 2007 2:38 AM
  • me being an IT guy too, agreed its not ideal. Also as an IT guy you have to know when to give in, way up the cost of fixing a solution with the time spent on problem solving. Learned long ago computers sometimes have wills of thier own. Exhaust all possibilities as soon as possible and move on. Believe me, it keeps you sane.

     

    If you spent 5  weeks trying to solve something that £30 would solve anyway, take te easy life. Its different if you are learning during this time of course, thats called on the job training :-)    (thats the only training i get)

  • Well here is my story.  I have a DLink Vonage Wireless Router that of course work fine with XP, I am running WPA PSK.  I did an upgrade on my home pc (Dell Dim 9100) to Vista Business.  I can not connect to the internet (wired) unless I use a Static IP.  The other day I did a clean install on my laptop (Dell Lat E1505) to Vista Ultimate.  Well samething, "Local Only" for wired connection ( I cannot use a static, due to connecting at the office also),  Unbelievabley I was able to connect via wireless "Local and Internet" however, it was not consistant.  I went to Dell's site and installed new drivers for both wired and wireless cards and I have the same issues, I have to reboot inorder to reconnect, even though I did uncheck the power setting, I unchecked IPV6, QOS and Link Layers to both NICS and still the same ***, sometimes after a reboot It will show 1 private network with both a wired and wireless connection, next reboot, wireless only.  What the hell is the deal here?  Is it Vista? or Drivers?  I keep searching and searching and cannot find an answer.  I also have many, many, many Error 5005, NETw4v32 in the system event viewer.

  • EUREKA!!! Now it works.

     

    Please check:

    "Connect automatically when this network is in range"

    "Connect even if the network is not broadcasting"

    in Wireless properties.

     

    I dechecked IPV6 too.

     

    Now my 3com router connect to Network connector Intel pro/wireless 3945ABG Driver 11.1.1.11 using WPA-PSK.

     

    I hope this suggest works for everybody

  • I am having this issue on an acer with an Atheros ar5005G.

     

    Here is what I have posted to Acer (OEM windows - pre-installed rubbish - would rather have had XP)

     

    When connecting to a linksys wireless router, the machine will not connect, the acer software actually pops up a message saying "internet disconnected" and when you diagnose, it reports as a time out. 

    This fault has occured in the last 2 hours, having previously worked all day, and previously there have been no issues connecting to this router over the last 2 months. 

    The machine will still connect to another network, and other machines can connect to this network.

    We have re-booted the machine and the router, powered off and on the W-LAN card, we have uninstalled and re-installed the network card.  We have also installed a USB wireless card to same effect.

     

    I have tried the hotfix posted earlier, and most of the other things suggested here, but to no effect.

     

    The laptop was bought just so my partner ould work from home, so it is now pretty redundant.

     

    As an aside, anyone know if I use the recovery stuff that we created when we bought the machine, will it lose all our new files.  We need this machine online!!

    Thursday, June 07, 2007 9:02 PM
  • A recovery will normally wipe the machine to the state it was in when you purchased it.

    I would have thought so, not sure if they had improved that side of Vista - I guess we may find out this weekend.

  • hello there

    I had the same problem on 2 wireless devices, and in one days I solved both problems Smile

    First device is an intel PRO Set 4965AGN with drivers version V11.1.0.86. I got
    no problem to connect to a network with no encryption and wep encryption. But no way to connect to a wpa encrypted network...
    So I upgraded to the V11.1.1.11 driver and I got it work Smile

    Second device is a Realtek RTL8187 usb adapter. At first Vista home premium didn't recognize it, so I have installed a first driver which was a V5.x one. Thus I got the device working with no encryption and wep encrypted networks, but not with a wpa ecrypted network.
    As there was very few options with this driver, I have installed an newer one (V6.x). And with it, it's working very well whith WPA encrypted network Smile

    So in my case everything was a driver-based failure...
    Friday, June 08, 2007 10:13 PM
  • Backed the machine up and restored it, and now it is working fine again.

     

    Noticed there is a new Atheros update on windows update, which I think was released just before the problem started, so I have installed the security updates and this update and see how it behaves for a week

    Saturday, June 09, 2007 10:29 AM
  • I'm reading all this trying to find help for our situation, and these symptoms are pretty close. Our newly-unpacked Dell E520 (desktop, not mobile) running Vista HB will connect to our wireless network (WPA2) for a while, then loses connection. Once lost, it will see the network, but not connect unless rebooted. Network card is Belkin F5D7000 ver. 7000, router is US Robotics USR5461. All drivers are the latest available. No connectivity problems with XP and 2000 machines on the same network. We've set global autotuning to disable, no luck.
    Saturday, June 09, 2007 10:28 PM
  • I have the same issues.  I have tried everything that everyone has submitted, but nothing is working.

     

    I do get to the point that it asks for my WPA Credentials, but after it goes through that it pretty much either times out or it asks for a Security Key/Passphrase, and this is on WPA-Enterprise.

     

    I have an Inte Pro 3945 ABG Network Connection, Vista Home Premium 32 bit.  I'm calling toshiba tonight...

     

    the Laptop otherwise works great with WEP and I can connect elsewhere.

     

    If I find anything else out i'll be sure to post it.  thanks for the help though, though here's a though, somene posted to decheck ipv6...how does one do that?

    Tuesday, June 12, 2007 11:27 PM
  • Right well for me (my boss) downloading the following driver:

    http://downloadcenter.intel.com/T8Clearance.aspx?url=/13001/eng/V11.1.1.0_VT_DRIVERS.ZIP&agr=N&ProductID=2259&DwnldID=13001&lang=eng

    disabling the power management feature of the adapter and disabling the ipv6 by doing the following:

    Disabling IPv6

    Unlike Windows XP, IPv6 in Windows Vista cannot be uninstalled. To disable IPv6 on a specific connection, you can do the following:

    In the Network Connections folder, obtain properties of the connection and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items. This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.

    (taken from techguys website)

     

    this worked on a Portege M400 with a Intel® PRO/Wireless 3945ABG wireless card connected to a 3com Officeconnect 54g wireless router using WPA TKIP encryption. Hope this helps somebody out there Smile

    Wednesday, June 13, 2007 3:26 PM
  • I tried that as well, but I still can't connect. 

    I found out more information about the wireless connection at work, it is WPA off of a radius server and it works just fine for windows xp, but not for vista.

    in the logs it states that authentication failed.

    This is what happens when I go through and try to connect, it either asks me for a passphrase/security key, it fails, or it keeps asking for credentials.

    I have verified my credentials with the supervisor and everything is fine.  The only people that are having problems is those with Vista.

    The latest firmware update that was released by Linksys has been updated on the router, so the blame has shifted again to Vista...which just doesn't seem right for an OS to have problems like that (can understand temp problems, but this looks like an ongoing issue)...anyone else with a suggestion that might help?
    Thursday, June 14, 2007 4:19 PM
  • Disabling IPv6 worked for me.
    Friday, June 15, 2007 8:15 AM
  • I have the intel 3945ABG connecting to a 3Com 3CRWDR100A-72 and still can't connect with WPA.

    Have tried the latest drivers for the intel 3945ABG as others have specified, also tried removing IPV6 etc..

    Everything was fine in XP.

    I don't particularly want to buy a new router... pretty annoyed as I can get wireless to work in linux but not in Vista!
    Sunday, June 17, 2007 1:15 AM
  • Hey

    i just had the same problem and was able to SOLVE it in this way:

     I switched the router operation mode from .11g with g protection enabled to mix mode: 802.11b + 802.11g without g protection.

    Hope it helps u in any way.

    Good luck

    Tuesday, June 19, 2007 10:14 AM
  • I thought I had solved it disabling IPv6 because it worked just one time but yesterday I started Vista and still cannot connect to my router. I'll keep waiting for a solution, I gess.
    Tuesday, June 19, 2007 11:44 AM
  • Oh....Still no body solve this problem.

     

    I think the only solution is waiting for the new patch form Microsoft.

    p

    I have the same issues with you~    The wireless in my office is use the WPA+ protected EAP properties (certificate)

     

    I use the same way in XP is OK.    so~~~I am sure the problem is caused by Vista.  

     

    Is there somebody who have contact microsoft tech department for this issue?

    Monday, June 25, 2007 4:46 AM
  • I have a similar problem to many described here: Vista Premium; 3com wireless 11g OfficeConnect firewall router; Dell XPS M1210 laptop; Intel PRO/Wireless3945ABG.

    Timeout Error when connecting using WPA-PSK

    Event log mentions: "Layer 2 security key exchange did not generate multicast keys before timeout".

    Have tried most of the solutions suggested here with no joy.

    One additional clue: I can reliably connect if I hold the laptop near (1-2 ft) from the router. Once established the connection works fine (I am using it now).
    Thursday, June 28, 2007 5:43 PM
  • Right ok,

     

    Having been on an upgrade programme at work to upgrade all our routers (upgraded to netgear dg834g from 3com office connect) I believe that one of the main causes for this problem is the officeconnect router. We had some XP laptops and a dell desktop on XP that were giving us the same error message, once I changed the router all items connected without a single glitch - I genuinely believe the 3com router is a liability and is causing all of your problems

    Friday, July 06, 2007 8:12 AM
  • It's definitively not a problem only caused by 3Com!

    I have an SMC Barricade 2804WBRP and I'm not able to connect with my Dell Inspiron (w/ Intel 3945ABG) via a WPA secured connection... I've tried all the hints posted here in this thread and none of them worked.
    Friday, July 06, 2007 5:01 PM
  • I just purchased a new Dell Inspiron 1705 with Windows Vista and I have the same issue - not being able to connect to the interent using my Belkin Router Model # F5D8230-4.  When I checked out Belkin's website regarding compability of my router with Vista - it indicated that Vista would have the driver required already included.  No luck.  Spent 2 hours last night with Dell's tech help - they are perplexed. Going to continue working with Dell to see if they can help me.  My old XL laptop works just fine!  Sigh.

  • I have a 3Com 3CRWDR100A-72 router and an Intel 4965AGN wifi card.
    I cannot connect with WPA (v1). The router doesn't have WPA2 capabilities.

    I tried some of the proposed solutions but none worked. When I came back to WEP it didn't work until I restarted the computer so, perhaps I have to try the proposed solutions and restart the computer each time.

    It is clear that it is a problem of Vista with WPA (v1). Let's see if MS address this.

  • I have had flaky connection issues with Vista with an Intel ABG, Dell 1500 (Pre-N), and Intel AGN (Draft-N) with both a Netgear and Buffalo WAP.

     

    I've made some progress though:

     

    1. To connect using WPA2, it didn't like it if I used a word as the password for the WAP. Use 10 numbers (like 1234567891) instead.

     

    2. To fix issues when moving between networks (not getting the new IP), set the DhcpConnForceBroadcastFlag to 0 per http://support.microsoft.com/kb/928233.

     

    Now if only I could stop the intermittent and random disconnects!

  • hi folks

     

    Click on the Start menu and type cmd in the search box. Type CTR+SHIFT+ENTER to tell the command prompt to open with elevated privileges.

     

    In the command prompt window, type netsh int tcp set global autotuninglevel=disable and hit Enter

     

    then restart the pc.

     

    i hope this will solve your problem.

     

    If the change doesn't help, you can always revert by going though the same process, but instead, use the command:
    netsh int tcp set global autotuninglevel=normal...

    but 11.1.1.11 but still it didnt work.. I have tried all the possibilites but still it didnt work..I think microsoft should address this issue. please help me.... it is a pian in the ***

    Saturday, July 14, 2007 8:02 PM
  • Same problem here. With one exception ...... WPA-PSK on Vista did actually work for me one time. Then the next day it was the same as everybody else here and I thought I had f*cked something up so I've wasted 2 entire days trying to solve it, which of course did not succeed. I'm the type of guy that helps everybody else with their computer problems and I usually get the job done, but not this time.

     

    What got this saga started for me was the fact that I've been using WEP-PSK for the longest time and it has always worked, even on the latest addition, my new Vista Business-preinstalled () laptop. Then one fine day I thought "well, WEP is not that safe so let's do it, let's switch to WPA".

     

    I'm glad I found this thread, so I can stop being frustrated and stop having these feelings of Computer-Directed Aggression, I know now that it's just not going to work. My router is an SMC7904WBRA (i.e., no WPA2) and the laptop's wireless is Intel PRO/Wireless 3945ABG. I've done everything that has been suggested here, the Intel driver is currently 11.1.1.11, I've upgraded the router's firmware to the latest (v0.55), tweaked all the settings I could think of and still no joy. At least I know now that Microsoft is to blame here. If this was the only thing wrong with Vista, I might consider switching back to WEP, but there are a few other things that I'm so annoyed with that I'm going to go back to XP. That has been my intention from the beginning, but I thought Vista deserved a fair chance. Well, it has had just that. Enough! Now I know. As soon as I'm able to make a full backup of this piece of junk, I'm back to installing XP. Good grief!

  • I have exactly the same problem with a new Sony laptop & a 3Com OfficeConnect 3CRWDR100A-72 router. I have tried all the work-arounds suggested in this thread with no success though, like ed1901, it mysteriously connected once whilst switched to automatic. Sony have been unable to help.

     

    I had given up hope and was about to go out and buy a new router when I had one last trawl of this forum and came upon "Vista won't Connect to Internet....".

     

    I tried JeffC69's suggestion, following Big Mak's comment re authority - and it worked! It took a couple of attempts to establish the connection initially but now, after several reboots in different locations, it seems to work every time.

     

    I shall report again tomorrow to confirm that this isn't just one of those M$ "oddities" but for now,

     

    We appear to have a solution!

     

    Thanks JeffC69 & Big Mak.

  • Same router here. But I have tried the solution reported there:

    In a command prompt with privileges run:

    netsh

    interface
    ipv6
    reset


    and I can't get my ahtec laptop with 4965AGN wifi card connected.

    I have tried both with long and short TKIP passwords.  Without success.

  • Petoro

     

    That's a blow - mine has been OK today, but we'll see what tomorrow brings.

     

    If I buy a new router, which I shall probably do anyway, as, because of this problem, I have now promised my (not very) old 3Com to someone else, and I set it up for WPA2, will it be compatible with machines running XP or older systems, which may not have a WPA2 capability? If this is a common problem (& 200 posts indicate that it is), then M$ have a real compatability problem which they don't appear to have addressed. Note that these posts go back over a year - to the early Beta days, in fact.

     

    Does anyone from M$ ever read these posts?

    Wednesday, July 25, 2007 9:37 PM
  •  

    "I shall report again tomorrow to confirm that this isn't just one of those M$ "oddities" but for now,"

     

    We probably do not have a solution!

     

    I read Petoro's comments late last night & tried again. Sure enough, as Petoro predicted, I couldn't get a connection. This morning, however, after a sticky start with an initial failure, I am able to connect. I have had several reboots, and the speed of connecting improves with the number of starts. The machine is less than 2m from the router, but this should not make any difference.

     

    My conclusions - Vista is not adequately backwards compatible with WPA or WEP (64 or128). This is a major failure on M$'s part. I accept that to make a new OS compatible with millions of items of legacy hardware is unrealistic, but WPA is not a piece of legacy hardware, it is an almost universal system.

     

    My actions - accept that, as ever, kicking against the might of M$ is a futile & timewasting exercise, & go out & buy a new router.

  • Solution:

     

    I've also been reading these posts due to the same issues with 3Com 100-A with PSK security.... Having spent hours (days!) troubleshooting, I've found that I'm able to connect if the laptop (Dell with Intel wifi)  is sat next to the router - then try to force the connection to your SSID, it connects first time, Every time.  Also moving the Laptop to a differnet room work stright away however I'm getting messages that suddenly my network key is incorrect (haven't see this problem before).  I'm wondering if we have several problems here, one being wifi environment issues and how Vista authenticates to the router.

     

    Please can you try this and let me know your outcome?

     

     

     

    Sunday, July 29, 2007 6:20 AM
  • I have never had an issue connecting - but if connected wirelessly the connection drops repeatedly and will only reconnect after system has been rebooted.  Error message is Event 5005 NETw4v32.  Works fine ONLY if physically connected to router.  Other issue in this brand new Dell Vista Business laptop is that it will not let me load Java.  Get "Failure Setting File's Time/Date Stamp" & later "Error 1722" message.  Tried all fixes as per WWW.Java.com  but to no avail.  Is there any connection between these two issues?  Is my redress against Dell, Microsoft or Intel?  Should I be patient or revert to XP?

     

    Any help, support or comfort will be much appreciated!

     

    Sunday, July 29, 2007 4:25 PM
  • No - I was wrong - I have just lost the connection despite being directly connected to the router (a BT Home Hub) rather than wirelessly.  Again all OK on rebooting until the next time.

     

    This is very exasperating!

     

    Sunday, July 29, 2007 4:43 PM
  • Not hopeful that this will get sorted, but another combination with absolutely no joy....

     

    Samsung R70, intel 3945abg v11.1.1.11, Vista premium

    Connecting to Belkin F5d7630uk4a with latest firmware

     

    Tried the power management option, disabling ipv6, and also on the router changing modes (mixed and g only)

     

    all of which make no difference what so ever when connecting using wpa

    great.

    guessing by the volume of posts and absolute stoney silence from microsoft, this isn't going to get sorted anytime soon, so its either carry on using a very long cable from work or get a wpa2 router

    oh, and keep my XP partition so I can use wireless in coffee shops / bars / thousands of other places that run wpa-psk..

Therefore, if you are not severely affected by this problem, we recommend that you wait for the next service pack that contains this hotfix. To resolve this problem immediately, contact Microsoft Customer Support Services to obtain the hotfix."

    I have the same problem. I have a Toshiba laptop with Intel 3495 ABG( driver 11.1.1)  wireless Network Adapter and US Robotics USR 9110 router with WPA TKIP encryption. I tried everything and I can only connect when I'm next to my router (in the same room) ,otherwise it takes 20-30 minutes to connect from another room (even the next room). My laptop with XP connects perfectly.

     

    The signal quality is excellent every room in the house, but can't connect with vista... Layer 2 security problems and timeout error.

     

    The drivers are updaed and IP 6 is disabled.

     

    Any solutions ?

  • <Apologies if this has already been mentioned (there's a lot of posts to look through!), but this link describes our symptoms exactly: http://support.microsoft.com/kb/935222/en-us> - Wideboy1 - 31/07/07

     

    Having read the details of this Hotfix, I agree with Wideboy1 that this would appear to be M$'s somewhat grudging acknowledgement that there is a problem. Significantly, the Hotfix is not available as a straightforward download - you have to contact M$ direct to get hold of it (or wait 'til next year for SP1). Not a very satisfactory solution, and their explanation of the problem is (deliberately?) vague. There is no mention, for instance, of incompatability with WEP 64 or 128, nor is WPA2 even mentioned.

     

    As I have bitten the bullet and, against my better judgement, bought a new router I have not tried the Hotfix. Has anybody else?

     

    Having studied this thread, and similar threads on other forums discussing the same problem (and wasted countless hours), I am now convinced that the problem is purely and simply an encryption system incompatability.  Vista is currently designed to connect wirelessly only with WPA2 encryption. It is not an IPv6 problem - if it were, there would also be problems with hard-wired LAN connections (or with encryption disabled), and everyone consistently reports that there are not. Incidentally, closing IPv6 on my machine cut off my expensive bluetooth mouse - not a good long term solution! There are consistent reports of occasional and sporadic connection with WPA, but the connections are not consistent or reliable. I am just grateful that I don't have the problem of one of the posters on another forum who is resposible for a WPA encrypted wireless network at a university with 25,000 staff & students, all logging on with laptops. Most of this year's freshmen will have Vista. Remember, too, that 40% of the PCs currently being sold are laptops, the vast majority of which will have WiFi and Vista.

     

    Mr Gates - this is a c*ck-up of major significance - accept the responsibility & get it sorted.

  • Hi,

    I have the same problem earlier described in this topic, but I don't get it solved by the hints given.
    The laptop is an Acer Aspire 9413, with Vista Home Premium running on it, and it has got the Intel Wireless 3945 ABG chipset in it. The modem is a Philips ADSL / PSTN modem/router (provided by Belgacom).
    When I try to connect to the wireless network (set as WPA with PSK, so personal WPA, with TKIP encryption) it says that it can't connect. However under windows xp there is no problem at all.
    When I set the encryption to WEP it works though, but WEP is unsecure for years already so this is not an option for me.

    In the Windows logging I can see (sorry for Dutch, translation to English at bottom)

      Beveiliging en verificatie

       Geconfigureerd beveiligingstype: WPA-PSK

       Geconfigureerd versleutelingstype: TKIP

  • BlackbirdJ71... see my post of July 31... looks like this won't be generally fixed until a Vista service pack is released. I gave up the fight and got a cheap router on Ebay that supports WPA2... problem solved.

    Hi Wideboy1,

    Thanks for your reply.
    I've seen your post too indeed, and checked your link out, it says:
    "

    SYMPTOMS

    On a Windows Vista-based computer, consider the following scenario:
    You use Wi-Fi Protected Access (WPA) together with Advanced Encryption Standard (AES) encryption to access wireless networks.
    A computer certificate is configured correctly on the computer.
    The computer has the correct permissions to access wireless networks.
    "

    So I thought it only applied to WPA-AES (not WPA-TKIP aka WPA v1 as I use), and I also don't use certificates to authenticate myself in a wireless network (just a preshared key).

    But that is just my 2 cents of course, let me know your opinion...

    Thanks & BR,
    BlackbirdJ71

  • Hi BlackbirdJ71... yes, I take your point, the wording does suggest that WPA-AES should work. I can only assume that Microsoft has for some reason omitted (or hasn't realised?) the fact that TKIP is also affected.

    Monday, August 13, 2007 3:49 PM
  • Hi Wideboy1,

     

    You probably mean, the wording does suggest that WPA-TKIP "should" work?
    Because they say there that they have a bug when u have WPA-AES (WPAv2) in combination with a certificate (= symptons).

    Or am I really misinterpreting it there??? Please reread the paragraph and tell me if u come to the same conclusion.

     

    BR,

  • I don't know how related this is but it may be the simplist fix that seemd to fix my problem.  on my network i had origionaly just wpa2 which runs on aes, and when my brother  came home i had to set it to mixed wpa and wpa2 because his older card deos not support wpa2. I did not think at first i had to change my settings on my wireless card back to psk. for a while i smacked my head from connection problems and then i turned to wpa2-psk for my wpa2 connection on vista and vua' la connects like a charm.

    the deals mixed (wpa and wpa2) runs psk and flat wpa2 runs aes.

    Just make a mention if this occurs to be the problem.

    Im sure that because Im on a microsft forum i don't have to give definistion but  Im going to put the quote from my dlink modem below.

    "Use WPA or WPA2 mode to achieve a balance of strong security and best compatibility. This mode uses WPA for legacy clients while maintaining higher security with stations that are WPA2 capable. Also the strongest cipher that the client supports will be used. For best security, use WPA2 Only mode. This mode uses AES(CCMP) cipher and legacy stations are not allowed access with WPA security. For maximum compatibility, use WPA Only. This mode uses TKIP cipher. Some gaming and legacy devices work only in this mode."

  • Sorry, BlackbirdJ71... yes I meant "WPA-TKIP 'should' work", in which case, maybe Microsoft just hasn't listed all the various permutations that this problem appears in.

    Wednesday, August 15, 2007 2:01 PM
  • On the HP DV9540 Disable the option in the power management for:  Turn this device off automatically to save power.  Did this, rebooted the machine and it was then able to connect. 

    Using the settings below on my wireless router.

    Channel: 6 (2.437 MHz)
    Authentication: WPA-PSK
    Encryption: TKIP

     

    Was able to connect fine at max speed with no issues.

    Thursday, August 16, 2007 8:58 AM
  • I have the same problem : No WPA connection under Vista.

    The strange thing is that is does connect when I hold the notebook directly next to the router (at just an inch or so), after which it stays connected anywhere around.

     

     

    Thursday, August 16, 2007 8:35 PM
  •  

    I have exactly the same problem with vista. It is so strange that it connects only when the computer is very close to the router. When I llok at the event logs I saw 'Layer 2 security problems'. I hope Microsoft will come up with a solution.

    For info my problem has now been resolved by the imstallation of the Microsoft Hotfix mentioned somewhere early in this thread. Hopefully this means that on general release it will also resolve everyone elses issues Smile

    Did you have to contact Microsoft to get the fix sent? or did you download the fix from a place?


    Thanks
    Tuesday, September 04, 2007 7:01 PM

    Could anyone please post the hotfix number ?

    Sunday, September 09, 2007 10:39 PM
  • I have also tried the hotfix, but nothing fixed fer me either.

    This hotfix probably only works for WPA AES and not with WPA TKIP as my modem uses.

     

    Monday, September 10, 2007 6:51 PM
  •  

    Not sure if this helps but since I posted on 7 June, we have reset to factory settings, and switched off auto-update for everything but critical updates.

     

    It has worked fine ever since.

    Monday, September 10, 2007 8:40 PM
  • Thx for the suggestions....this makes sense, since I installed the hotfix and it did work for a day or two and then I got the problem again...possibly due to Windows Updates. I will try your suggestion and let you know.

     

    PS : I'm using TKIP.....

  • i have read thru all message here and tried everything (it seems) but i still cant get my new Laptop (Acer) to connect to my router (3com) when encrypted.

     

    i get the 'timeout' message

     

    i have tried sucsesfully to conect to the internet when wireless not encrypted, and also direct with a lead to the router.

     

    but when i change back to encryption WPA - TKIP i cant connect

    i have downloaded the latest vista updates and the hotfix and the latest drivers. i have ticked and unticked the various setting including turning off eNet and IPv6.

     

    is there a fix, apart from spending more money and purchasing a new router!!! have i just wasted £500 on a new computer that i cant use!! (no good without the internet)

     

    Help

     

    Wednesday, September 12, 2007 7:36 PM
  • Doesn't work here either. I have installed KB935222 on my FS Amilo SI1520-23P. Router I'm using is D-Link DI-514 which doesn't support WPA2.

    Guess nobody yet has generic solution for this issue.

    Hope to have SP1 soon.

  • My combination of Win Vista Home Premium, Zyxel G1000 (V3.50(HH.7) | 05/15/2006) and Sony Vaio FZ11S (WPA-PSK+TKIP and b/g mixed mode) has the same problem, while my 'old' DELL D600 worked fine on the same G1000 with the same settings. WPA2-PSK+TKIP not working either, in this case :-(

    Contributes to the suspicion of many: WPA-PSK+TKIP problems in Vista...

  • Hi All,

    I'm running a HP Pavilion with Vista Ultimate 64bit

    Well this problem I had to and was driving me MAD!!!! anyhow after talking with "Belkin" they told me i had to set up the security settings on 64bit WEP.(in the Router setttings) Change the Name of the Connection to include both Letters and at least one numeral.

    Change wireless channel to 6

    as follows:

     

    Wirless- Security-security mode:

    Change to 64bit WEP

     

    In - Wirless- Security-WEP

    change settings to 64bit WEP

     

    "In Key 1" add two digits to each box (password)

     

     

    Wirless-Channel-SSID

    Change wireless channel to 6

     

    In-a-nutshell- Belkin were fantastic, try your Router Manufacturer, you just never know

    Hope this has been of some help Guys!!!

    Wireless wth 64 WEP never was a problem with VISTA, howere everyone seem to having problem with with WPA-TKIP, alternative at the moment is WEP, but it is very easy to crack in under 2 mins (if you know the tricks)


    Tuesday, October 09, 2007 7:59 PM
  • i have a problem that if use WPA - vista says the key is different that in router if I use WPA 2 or WEP vista says that set up in computer is difrent that set up of the network. if i make "open" network then vista says "cant connect because of unknown reason"
    Friday, October 26, 2007 10:18 AM
  • they did and it worked for me (vista ultimate connection with philiips dsl router w/ WPA/TKIP:

     

    search for KB935222 and request the patch. You'll receive it within 6 businness hours. Installed it, rebooted and everything worked!

     

    Saturday, November 10, 2007 8:49 AM

    Using WPA-PSK ( TPIK )

    I have the same error 6100: timeout

    Some Idea?

    Thanks

  • Nor do i got it work, I still getting the time out error with WPA-TKIP, but Microsoft already mention the patch is still in evaluation stage so... guess have to wait again
    Monday, November 12, 2007 3:50 PM
  •  

    Recently bought a Samsung laptop running Vista Home Premium. Got it home, installed everything and then tried the wireless LAN card to connect to my Belkin F5D7630 wireless router (which is perfectly OK and working a WPA/PSK password on an XP laptop). Initially it worked OK, but after it Vista updated itself before I could switch auto update off, it rebooted itself and then wasn't able to connect to the WPA/PSK/TKIP wireless router. It was able to connect when I made the router 'open access' and it works fine when I make the router WEP, BUT IS DOESN'T want to know about WPA!!!!!! It just says authentication time out error and I end up going round in circles trying everything I know but without success.

     

    Samsung suggested a) returning the laptop back to 'as shop bought' mode using their inbuilt recovery software, didn't work b) using a microsoft KB article to fettle the Registry!!!! no less, didn't work c) trying a hotfix patch from Micosoft, didn't work d) RE-INSTALLING Vista from the recovery CD having formatted the drive (remember this is just out of the shop!), didn't work..................so eventually I have sent them it back to the workshop and they have currently suggested it needs a new wireless LAN card????????????? I hope they haven't just assumed it is faulty without tetsing it, or that they make sure the replace it with a different make, as otherwise I can't see why I won't have the same problem. To me, it feels like a Vista glitch because for an amateur I have tried some pretty hard core telephone advice so far...................I seem unable to get any more of a Firmware update for my router, but when I rang Belkin they were ultra confident their product wasn't the problem.

     

    The wireless car is given as an Atherus brand, can't remember the model number, but I don't see how hardware can be faulty when it connects in 'open' and 'WEP' modes but not WPA???????? Unless it is the driver for the LAN card at fault, but I don't see a more recent driver for it and Samsung haven't sent or suggested I need one. Anyone taking bets on Vista? or will Samsung actually solve the problem?  

    Wednesday, November 14, 2007 11:37 PM
  • Guess what? Laptop back, supposedly a new wireless card, but same old problem. I strongly believe this is Vista related and however much I am getting told to get a new router, update the un-updateable firmwares and drivers (the hardware companies don't have updates as they say I'm up to date and they are Vista compatible!) I am looking at installing XP even though I bought this laptop in good faith with Vista pre-installed. Scandalous.

     

    Belkin have tried to help, Samsung have tried to help, but what can they do against a very poor OP and Microsofts insistance that bugs happen, we can't test them all? Well, Microsoft, I wish I could only pay you £20 for your rubbish and tell you that I can't pay you full price for 1/2 tested software...............

     

    If anyone out there has a solution other than those already posted, I'd love to hear it.

    Tuesday, November 20, 2007 2:24 PM
  • what i did to solve this incompatibilty betw vista and XP:

    1. i change my router settings to WEP-shared

    2. use a passpphrase instead of using the default(it has to be 5 ASCII or 13 depending on the key encryption)

    3.apply the same settings on the XP which is quite easy

    4.on VIsta you have to choose no authentication to be able to have the option WEP(or else you wont have it) and enter the same passphrase as on the router

    5. make sure you have DCHP enableon the router and you have enough IP @

    6. applly DCHP on the vista and XP machine

    hope that i did help

    thanks! and enjoy Vista

    Well, this solution worked for me. Thanks, Heggie.

     

    This was driving me crazy… finding out there’s 150 other folks with the same problem was a mixed blessing.

     

    It’s User Communities like this one that prevent me from turning back to a Stone Tablet with a Chisel.

     

    Thank you all for your input.

     

    Lar

     

    P.S.   After two weeks with my new HP laptop, I hate Vista. I know… Microsoft wanted an operating system that even blithering idiots could use… so now Vista “helps” me at all sorts of things… where I do not need nor want help, and such “help” has cut my productivity to a quarter of what it was under XP. I really think that Vista should come with an installation option which asks: “Are you absolutely and incorrigibly ignorant when it comes to computing? Yes or No?”  If you answer yes, it should install Vista. If you answer no, it should install XP.
    Thursday, November 22, 2007 9:29 PM
  • Thanks for the extra help about WEP, but the thing is I didn't have a problem connecting with WEP using Vista, it is a problem to connect with WPA..........which as I understand it from manufacturers advice inc Microsoft is the prefered encryption security above that of WEP.........so obviously I and many others want Vista to connect with WPA enabled.....which it doesn't do 100% all the time on every machine, whether this is an issue to do with Vista installation or router firmware compatibility or just a bug in the WPA communications.........I don't know, but so far nobody has resolved it for me, and the nice Samsung Techie bloke siad the XP option was one that most people were taking.... 

     

    My solution was to take the brand new laptop, purchased with Vista (at a cost) and trash it in favour of XP Professional. It now works a treat connecting with WPA.

    This isn't the thread to discuss why Vista? But so far I fail to see why XP is being binned as an OS when it clearly is now Microsofts premium bug freeish offering....its purely a commercial decision to force the sales over again to a new OS.

    Well after reading the posts going back over ONE YEAR to the BETA days, for the same Fing issue I am having makes those New Apple VS Vista Commericals more believable, and very accurate :-)

     

    Anyway needless to say I am running Vista 64 ultimate, using an ASUS M2n32-Sli Wireless MB, (Realtek AP Solo Wireless Chip), and Sure enough the ONLY way I can connect is with WPA off!

     

    I WILL NOT run WEP, it is a Joke for security and I have to much to lose if Hacked.

     

    You would Think By Now MS would have some sort of fix, for such a SERIOUS Problem!

     

    Will keeep checking back, and crossing fingers while I use my standard Cat5 Connection ;-(

  • I bought a new vista-notebook last week with an Intel 3945 wireless card and had the same problem with a Zyxel router with WPA TKIP encryption. It worked  with a Netgear Router, but not with the Zyxel. I always got the timeout from multicast like described before. I could solve the problem by installing the XP driver from Intel: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=N&Inst=Yes&ProductID=2259&DwnldID=13000&strOSs=44&OSFullName=Windows* XP Professional&lang=eng

     

    Hope, it stays solved...

     

    ...just for one day. Now Vista has problems with the driver...???

    Wednesday, November 28, 2007 6:18 PM
  • Same problem here with an Asus F3Sv laptop connecting via a 4965agn intel chip to a 3com OfficeConnect router with WPA/TKIP. Router works fine with 4 other wireless devices, just not with Vista yet.

     

    Intel now have a version 11.5.0.32 driver version available for my version of Vista but this hasn't worked either. Oddly, I also initially experienced two successful connections (when I wasn't trying to make it work) but since then it's not worked at all.

    Monday, December 03, 2007 1:40 PM
  • Hi ,
       Just as a mention ive had almost perfect connection on wpa2-psk running 802.11n on my schools wireless internet. The description of my card just says "11a/b/g/n/ wireless lan mini-PCI Express Adapter"(and as far as i know its draft 2.0) with an atheros driver version 7.3.1.42 with driver date 6/18/2007.

    Vista doesnt reconize 802.11 n and "N" but it deos connect nicely.

    I dont know how much help this is but I thought Id let you know its been working with the above settings.
    Monday, December 03, 2007 3:25 PM
  • WPA2 works mainly fine as well as WEP. The biggest problem is still to connect via WPA.

    My router (D-Link DI-514, also tested on DI-524) connects when I change the settings of my wireless connection from WEP to WPA and let's me work normally but after shutting down and turning on again it doesn't work anymore. There must be some hope still left we'll get this *** finally working someday.
    Friday, December 07, 2007 2:28 PM
  •  

    Finally I solved it. I have D-link DIR-655 router that is connected via LAN to my Vista 64bit computer. The wireless computer use d-link DWA-547 on a XP 32bit computer. 

     

    From start it only worked with WEP or no security. I tried both WPA and WPA 2 and it did not work. But that was when WPA2 tried to use Cipher Type TKIP. When I swithced to AES I got full speed.

     

    Hop this helps some of you!

    Saturday, December 15, 2007 7:43 PM
  • Hi have the same problem. Vista does not connect to WPA. My XP machine works fine. I am just not willing to downgrade to WEP or unsecure connection. Can not believe that Microsoft still has not fixed the problem.

     

    I use the following workaround: I boot the Laptop like 2 inches / 5 cm away from the router. Then Vista connects. As soon as it is connected I can take away the laptop from the router and it mainly stays connected.

     

    Not exactly high-tec but at least I have a secure wireless connection.

    Monday, December 17, 2007 4:36 PM
  • Yep, same problem here. Dell Inspiron with Intel wireless 3Com OfficeConnect wireless. This has to be a power issue / authentication, if I can not connect in the same room as the router it's self. I too can connect either standing 2 ins aways from the router or in the next room.

    This is plain madness....  This forum's been going for nearly a year now with no resolution.  Not evan RC1 of SP1 Vista resolves half the problems that I had....

    You guys are going to love this..... I was thinking last night about being able to connect either 2 cms from the router and another room...

     

    By putting tinfoil on the aerials of my 3Com I'm able to connect stright away! I'm amazed. really!   I'm going to burn my MCP certification.

    After much googling for this issue, this thread seemed to be the only useful place out there (even if there aren't too many answers! Smile).

     

    I've finally got my 3com router connecting to my intel wireless card (inside a Toshiba laptop). I upgraded both the wireless card driver (didn't seem to do anything), but also the firmware for the 3com router. Everything's working fantastic now. Maybe worth a try to others in the same situation?

    Thursday, January 03, 2008 4:53 PM
  • Ok, so my last post may be a bit of a red herring! I just uninstalled the trial version of Norton on this computer and now I'm back to square one with trying to get it connected tothe 3com router with WPA!! Sad

     

    The weird thing is, that before the uninstall of Norton I rebooted/turned off the laptop numerous times to check it wasn't just some fluke, it's just that after the uninstall of Norton /bang/ it didn't work anymore.

     

    I've given up now, and downgraded my router to WEP 128bit, everything seems to be working fine in this mode - although I do worry about the decreased security... Sad

     

    Friday, January 04, 2008 11:08 AM
  • Just to let you know that the decrease power output from using the foil is working really well. No way am I going to go back to WEP.

    As many others have said this seems to be a Vista-specific issue and we can only hope that Microsoft will issue an update soon for those of us who cannot use WPA2.

  • Hi all,

    I have an Acer Aspire 5315 with an Atheros wireless card that I want to connect to a SMC access point.
    I also have problems when using WPA2 and AES, but everything works fine when the Laptop power cable is connected.
    This is very strange, if I remove the power cable the laptop is unable to connect to the access point.
    I already saw the power management stuff, changed settings so the wireless card isn't turned off to save power, but it stills not working.
    Does anyone else has this particular problem? Any solution?

    Thanks.

    Hi everyone,

    I have been coping with the same problem for a while now. However lately I have noticed that if I connect the laptop with cable to my router, the computer picks up the wireless signal after a while (3-4 mins). And after that point even if I disconnect the cable I can get my Vista laptop to talk WPA to my ADSL router without a problem. I am curious if this is the case for other people here in this thread as well.

     

    Regards.

    Hello. I've also de 4965agn (11.5.0.32) and a Windows Vista Bussines 64 (HP Laptop). The router is a 3com 3CRWDR100A-72 (v 2.05). I also initially expperienced one successful conection (WPA-TKIP, NON BROADCAST SSID), but never works again. With WinXP no problem, an also with a Vista Home Edition¿?. ¿have you find any solution????

    I got exactly the same problem, I have a Belkin N wireless router hook up with cable to my desptop with XP windows without problems. My laptop (with Vista) can dectect my router, but can only connect with NO security password set. I have try to set WEP, WPA,  WPA2, my laptop can still dectect the router, but it just can't connect.  I try to download the vista patches that you guys list, but still can't connect.  What can I do now? The thing I can think of is either connect without a security password (which I think is quite dangerous), or change my newly bought laptop operating system back to XP....=(

  • Just out of curiosity are all your pcs vista and do they support all wpa2. I had the nightmare when my service provider said to run thier wireless modems and turn off my draft n router to test if it was them or me. The modem ran wpa and g. the range sucked and had comunication problems to my vista pc. As soon as they found it on them i put back on wpa/wpa2 (though if you have an n router and all people are capale of wpa2 they should since im using wpa on some my N connection sits at 54 mbs due to a sibling that refuses to be wpa2 capable)

    forget this thing called wpa1 . Crawl under your associates desk and set them up for wpa2.  As soon as my sibling leaves im going back to full wpa2 support.

  • Hello again: in my case (Vista Bussines x64, 4965AGN,  3com 3CRWDR100A-72 v 2.05) wlan works fine with WEP128 bit. No possible with WPA.

  • after hrs and hrs and trying everything on this forum and more,

     

    wpa-psk (wpa-personal) aes with passphrase as network security key worked for me.

     

    make sure under "manage wireless connections" and "profile types" choose "use all-user profiles only (recommended)".

     

    when you double click and are on properties tabs - under "connection" choose both "connect even if the network is not broadcasting" and "connect automatically when this network is in range".

     

    With this even though under "connect to a network" it says "the settings saved on this computer for the network do not match the requirements of the network"

     

    under "network and sharing center" it shows the computer connected to the access point/router and the internet. i went to a few sites and made sure the lan cable was not plugged in and it worked.

     

    thanks to all for help. i have the patch installed, every setting recommended here set up, plus what you see above. i have an on-q home wireless access point system with motorola wa840g equipment. the network always has worked with simple settings with 2 other windowsxp laptops. now the new hp pavillion windows vista finally is working too.

  • Hi all.  It seems, if im not mistaken, that most of the people who post here are using laptops with onboard wirless adapters.  I have an ASUS motherboard with onboard wifi adapter, which has the same charateristics as almost everyone else (only connects with WEP or no ecryption)  HOWEVER, i also have a linksys usb dongle adapter that connects PERFECTLY with ALL encryption methods.  My router is a Linksys WRT54GS running dd-wrt micro.  Any ideas?

  • I have the same problem as everyone else here. I have a D-Link Extreme N (Dir 655) Router... I have my PS3, PC, PSP, & Laptop all connected to the network...The PSP and Laptop are both wireless...my laptop is running vista with a Marvell Topdog Wireless N card built into the laptop. I am right now just using MAC address filtering and not broadcasting my SSID because like everyone else WPA with TKIP doesn't work properly. It connects when I first open my laptop and from there it seems like every 5-15 minutes it jumps in and out of connection. I have tried everything I know plus talked to my IT guy at work and hes given me a few ideas but nothing has helped. It has to be something with the laptop and router not communicating because I can use WPA TKIP & my SSID set to invisible and the PSP connects and runs without interuption. Hopefully a fix or something comes because I don't want to use WEP which doesn't support wireless N only G and lower. If anyone finds anything please help us all. Thanks

  • Thought I'd add my voice to the chorus. Vista with Toshiba P205-S7806 with Atheros AR5007EG drivers 7.4.2.15. No SSID, no connection. Yes, I checked the "connect even if not broadcasting ssid" thing. Yes, I've been able to connect to it randomly - and why it decides if it is going to connect or not is anyone's guess. Don't get me started on why my vpn doesn't work on the wireless when it finally decides to connect either.

     

    This is stupid. A brand new vista ultimate setup, a brand new laptop and I can't connect to a stupid wireless router. Thanks alot vista. Every other lappy I've had works fine. This most definitely is some kind of vista stupidity.

     

    Where's XP's "repair" option in vista to give the stupid wireless a swift kick in the jimmy? At least if xp got confused I could get it to restart the wireless stuff and try to reconnect.

    Well I think I figured it out...I took a few peoples advice from this thread and from doing some research I changed my security from WPA TKIP to WPA AES...Since doing this I have not had a connection problem for almost a month and also my wireless seems to be a bit faster...Hope this helps....if not google "problems with vista and wpa tkip" a lot of forums and answers came up there.

  • I'm another "me too" I'm afraid with no solution.

    Brand new HP Pavilion dv9667ea / built in wireless and running Vista Home Premium.  Can't connect reliably to my Ozenda router using WAP security, but connects quickly and every time when using WEP.
