Unidentified Network Problem

    Question

  • I recently re-located my computer from underneath my desk to on top of it.  Although it was working perfectly before, when I hooked all the cables back up again, much to my dismay, I was no longer able to connect to my home network.  I tried all of the standard renew/release IP diagnostics, and ran the configuration tests, and nothing worked.  I am baffled that simply unhooking my network cable, then re-connecting it could cause such a problem.  I will walk through the steps I have taken to try and solve the problem, and welcome any feedback or solutions on the matter.

    1.  I disconnected the ethernet cable from my PC and connected it to my laptop (which I'm using now) to make sure that the cable wasn't my problem.  I disabled the WiFi adaptor on the laptop, and was able to connect to the network and internet using the ethernet cable.  (ruling out the cable as my problem)

    2.  I reconnected the ethernet cable to my PC, disabled my LAN adaptor, re-enabled it, and watched the status go from 'Identifying. . .' to 'Unidentified Network'.  So, I ran the network diagnostic tool, and it gave me three options .  'Automatically get new IP settings' which did not solve the problem.  'Reset your router' which also did not work.  And 'reset the LAN adaptor' which didn't work either.

    3.  Used my laptop to download the new driver for my LAN adaptor, burn it to disc, install it on my PC, then update my driver.  Problem is still not solved.

    4.  Starting to get desparate, I disabled Windows Firewall, reset my LAN adaptor, and I was still receiving the 'Unidentified Network' message. 

    5.  Re-enabled firewall, changed network settings to Private, from Public (which it was defaulting me to), turned off all file sharing and reset the LAN adaptor again.  Still got the 'Unidentified Network' message.

    6.  I went into the Properties menu of my LAN adaptor, and looked at what it had for an IP address. . . To my surprize, it was getting 169.254.90.121, with a subnet mask of 255.255.0.0.  I do not know if this is window's default IP address when it can't connect to anything, but what I should have seen, had it been working properly was 192.168.1.64, subnet mask 255.255.255.0.  So now clearly, something is stopping my LAN adaptor from communicating with my router.

    7.  Call MS Tech support. . .They can't help me.  Well, they can't help me for FREE.  Turns out because I bought the OEM version of Vista I have to pay for tech support.  Fortunately, the Techie from MS was nice enough to give me this piece of free advice. . . 'call your ISP'.

    8.  Called my ISP, repeated steps 1 - 6.  Banged head on desk. 

    9.  Visually inspected my router, and noticed that the port that my PC was connected to IS indeed lit up, showing that it knew something was there.

    10.  Used the laptop to access the router's configurator, and did not see my PC as an active connection.

    11.  Lost all hope.

    This has been a really frustrating problem because everything WAS working properly until I unplugged all of the connections from the back of my computer, then re-connected them all 10 mins later.  I have read through most of the posts on networking problems, and couldn't find any answers, so I'm starting a new post in hopes of finding one.

    My vitals are:

    O/S: Windows Vista Home Premium OEM 64-bit Edition

    Processor:  AMD Athlon 64 3200+

    M/B: Gigabyte K8 Triton K8T890

    LAN Adaptor: Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller

    LAN Adaptor Driver: 9.16.2.3

    Modem/Router: 2wire 2700HG-E Gateway combo unit provided by Telus

    Any help would be greatly appreciated.  Thank you.

  • Ryan;

    I'm feeling like deleting Vista and reinstalling XP.  Whoever wrote this OS obviously never used it.  Most unproductive piece of junk that I ever brought.

    Forgive me but I'm absolutely, like you, at a loss.  This so called secruty sucks.

    My wireless router stop working.  I bought a new one.  I serves the computer I'm typing on as well as my laptop. The Vista computer, freaking clueless.  It won't accept the IP from the router.  Reset the router.  Rebooted the computer.  I tried the network  cable on another.  Cable works.  I went into the Broadband setup screen.  It wants a user ID and PASSWORD.  Earth to Microsoft, Comcast doesn't require this.  Disabled network adaptor and then re-enabled.  CMD will let me get to command prompt, but as the owner of this dam computer, I don't have the authority to use ipconfig /release & renew.

    What a waste of money.

    I'm working on it.  But dam Microsoft can take their dam software back for all I care.  This is my son World-of-Warcraft machine.  It hasn't been used in a week or since I changed the router.  Again do these morons at Microsoft actually use their software.

    If I get banned, so be it.  You know, maybe those Macintosh commercials are right!

  • Imustbecrazy,  I will give the other forum thread a shot, thanks for the advice.  Also, in regards to the command prompt not allowing you to use ipconfig /release, etc. . . because it requires you to be superuser, if you right click on the command prompt listing in the start menu, then select 'run as administrator' you can do everything you were able to do in windows XP

  • You should check to see if the RJ45 network connector on your computer might have shorted pins. I find this all the time were removing your network cable pull the pins on top of each other. If the pins are crossed you will need to replace the connector.

  • Hi Ryan:

    No fix for you, mate, but just to commiserate -- I've the same problem and have tried all the same steps as you. Oddly, I only get the problem when I try to use the wireless router -- it's OK when a connect thru the Ethernet cable.

  • Hi there,

    I work for an ISP in Canada and have dealt with multiple customers who have purchased new Vista computers and have this exact issue. The first person I spoke with had a NVIDIA NIC, and doing some research yielded results that pointed to a possibility that updating the NIC drivers solved the issue. That being said, I have spoken with others who have different NIC vendors but the same issue, and no resolution.

    It must be an issue within the Vista OS, I wouldn't think it would be a driver issue as it doesn't seem to be specific to one NIC vendor. I do find it hard to believe it is something widespread with all Vista installs, as there would be many more reported cases of this issue.

    Edit: I should also point out that the customers I have dealt with are not using routers, and the Ethernet cables are coming directly from the cable modem.

  • I've had this same issue with my machine, it is a Thinkpad R51. I used to have XP on it and everything worked great. Now that 'm on Vista I cannot connect to the company's wireless network.

    I am one of the admins so save the noob posts about SSID, WEP etc.

    I can connect just fine at home using my linksys wireless router and I can also connect at other sites of the company which are using sonicwall access points.

    Currently in this building we are using Cisco 1131 series access points.



    EDIT: After lots of frustration with this issue just now I got it running I know this isn't a good solution but it's a start.  I went to my network properties and setup a static ip address for the wireless network.  This is fine if you don't roam a lot.  I hope that helps.

  • Well, I didn't really solve my problem, but I did find a driver for my wireless adaptor, and was able to connect wirelessly to my network.  But I am still searching for solutions about my LAN adaptor.

  • It is definetely a bug in Vista. I've had the same problem.

    Simply uninstall and delete all LAN and Wireless adapter drivers and let Vista to detect and install them again. It will resolve the issue.

  • I do have exactly the same problem. Very frustrating, indeed. 

    How can I uninstall and delete all LAN and Wireless adapter drivers and let Vista detect and install them again ? I have an OEM Version Vista Home Premium on an HP-Pavilion m7770.

  • 1. Right-click on "My Computer" and click Properties

    2. Click on "Device Manager" from the left column

    3. Expand "Network Adapters" Section

    4. Right click on each network adapter and click "uninstall"

    5.Click "Action" from the toolbar and Select "Scan for hardware changes"

     

    Hope this helps

  • I had the same problem as John Fortin in that my wireless would not work the second time, but my Ethernet cable worked okay.  But one oddity of my ethernet cable was that when i plugged it in, it identified it as "Network" and not the actual name of my network. 

    I tried unistalling and reinstalling both my drivers, but to no avail.  But, while messing around in Driver Manager, I had highlighed my Wireless Device Driver and then clicked Action>Update Driver Software on the toolbar. 

    To my surprise, while it was searching for updates, my ethernet cable connection changed names to the right network name, and not the generic "Network," and when it finished updating, I was able to once again connect wirelessly. 

    Although exceedingly weary at first, considering the fact I spent 4 hours trying to fix the problem, I completely shut down my computer, and turned it back on and it was still working. 

    There will of course be different hardware in computers and updates may or may not be available.  Also, by reading the thread, and doing all the same procedures such as resetting my router and such, it seems almost certaily a Vista OS problem moreso than a hardware problem.  I am not sure why it helped, and it may only be a temporary solution, but, for now, it is working.

    Thank you for your help, and I hope this helps others.

  • Possible Solution;


    Try reseting your router to the factory settings (either with the small pinhead button on the back, or withing the routers configuration). This worked wonders for me, as the router was saving connections from XP, and assuming they would be the same for Vista. Hope this helps,

  • I have a strong suspicion that the problem is actually caused by IPv6 in conjunction with this router.

     

    Try this:

    1. Control Panel > Network and Sharking Center > Manage Network Connections > right click your Friendly Neighbourhood Network Connection > Properties

    2. Under the Networking Tab, uncheck Internet Protocol Version 6 (TCP/IPv6)

    3. Exit the dialogs.

     

    My wireless connection immediately reconfigured itself and connected to the net. I am thinking this could quite possibly affect wired connections as well.

     

    Hope this helps.

  • I've been having the same issue.  I'm so frustrated with Vista that I'm returning my new laptop and getting a refurb with XP.  I'm getting the problem when trying to connect to the wired LAN.  I have no problem connecting to wireless.  I've also gone through the thread and tried everyone's solutions and none worked.  In this internet age, a bug in connection is a huge drawback.  The Mac commercial is completely accurate.  I definitely got a taste of reality.  Microsoft, how about we test our product before releasing it.  Vista pretty much sucks.
    Wednesday, March 28, 2007 4:06 AM
  • Hi, All you have to do is to find out what the dns address is for your router, then, find out what the last allocated ip was from that router, and manually enter it into the ip settings for your network card, on the problematic network, this should solve your problems.
    Tuesday, April 03, 2007 8:20 PM
  • Great news! Marvell Yukon released a new driver for my LAN card, and it's working again.  Turns out it was out of my control the whole time. . .
    Thursday, April 05, 2007 8:49 PM
  • It is a bug in Vista.
    Vista does not preset a MAC address for the network card.
    As a result the network card identifies itself as: 00-00-00-00-00-00
    this causes problems with any standard equipment.
    To fix this go to:
    Device Manger and view driver details for the network card.
    Select MAC, you will see that the option Not Preset is ON.
    Check ON the option to set a MAC address and type in a 6 hex digits e.g.:
    001a2b3c4d5e

    Save and restart your network. It should be working now.

  • I have been having almost the same issue.  My Specs Are Below.

     

    Gigabyte Borad dual eathernet ports, dual bios, dual sli. 

    Amd x2 2.6mhz.

    Corssair XMS 2GB memory.

    Vista x64

     

    I am also trying to connect to a 2 wire network router, I took an old wirelss card that was g and b ready out of my old system that is running vista 32-bit and put it in my new system.  There were a total of 3 network cards in the system, one wireless and two wired, the only one being used was the wirelss cards.  I put the right key in the system for wep, this did not work.  Every setting I put in the system would not work.  I even went out and bought a new usb network card same thing.  But wait it gets better my old system is nothing special it barly will run windows vista.  When I took out the network card that I had swiped from the old system back in it did the same thing.  The network card made the 2wire network that it was connected to an hour before now had the unidentifed network issue with outlook not so good. I have been a tech for a number of year and I can say that this is one of the weiredist thigs I have ever com accross. 

    I removed ipv4,no go.

    Ipconfig release/renew,no go.

    changed every setting in every network property, no go.

    The only thing that I can think of is the software that normaly loads in older versions of windows is not loading in vista, I am running the driver only.

     

    If anyone can tell me whats going on that would be great thanks.

  •  

    I also have a 2Wire router. It's from AT&T/SBC Yahoo DSL service. The model # is 2700-HGB.

     

    I have the security set to WPA-PSK TKIP. The password is 26 numeric digits in length. Wireless Channel is set to 6. Power setting is at 10.  Wireless mode is 802.11 b/g.

     

    We are using a Compaq SR5050NX desktop with a Belkin USB Wireless adapter.

     

    Any suggestions or workarounds? Vista identifies my wireless network (along with the neighbors) but cannot open IE, even though it says I am connected. AT&T technical support says it's a Microsoft problem, but who do I call at Microsoft? I've tried connecting to the neighbors to see if I can open IE, but the neighbors have their security set to WEP , so I can't get in that way.

     

    Any help is appreciated! Thanks

  • That sounds like a different issue than what is discussed here, but if you can't Google it, I will post the toll free number to MS tomorrow whilst at work.
    Tuesday, May 29, 2007 5:02 AM
  • I noticed that when I disabled the tcp/ip v4 and v6, it quickly recognized multiple networks as mentioned in earlier posts. I simply went to properties of the v4 and told it to obtain ip address automatically and that fixed my problem. I experienced all the same symptoms aforementioned but made no changes until the post about disabling v4. that did not work but as I mentioned made me realize that the automatic selection would pose a possible solution and it did. hope it helps, see yah!!!

  • linuxway, Thank you so very much!  The address was exactly the problem.  I noticed that the address was blank before I read your post, but I never thought to make up an address to fix the problem.  After putting an address in, I'm back on the internet.

  • unidentified network - the (re)solution   (< this is a searchstring for many frustrated Vista users)

     

    You probably have a router that's about 3 to 4  years old, it supports 100T and you see no reason to replace it. You have upgraded the firmware to a version that officially supports XP, but there is no official Vista-supporting firmware version (yet).

    Well, that's my situation. The new firmware version shows in the settings (under the chapter NATP) a tab about uPnP that was not there before, or at least in don't remember it. These uPnP settings allow me to choose 'Full uPnP' /  'Secure uPnP'  /  'No uPnP'.  It is by default set to 'Full uPnP' and that is with high probability an XP compatible setting. The thing is that Vista apparently requires a more restricted setting, otherwise it will not allow you to connect to internet. After changing this setting to 'Secure uPnP', 90% of my problems vanished - restarting my pc brings me to the LAN and internet rightaway, though resetting my router brings me to LAN rightaway but not the internet (showing an 'X'). One repair of the internet 'X' brings me to the internet in 1 second. Wow, that's a progress really. (So, do not reset the router, no problem heh?)

     

    Moreover, my network-setting of 'private' is really remembered now, as is the 'network discovery' setting. This latter has been turned off manually all the time, because it influencs your firewall settings. I still have to test that in the new settings. Firewall is off through group policy (dos-box: secpol) because that's what my router is supposed to do and is doing very very well too.

     

    You should search for Microsoft's 'Internet Connectivity Evaluation Tool'. This tool evaluated my router as fully compatible EXCEPT for uPnP compatibility. After changing the router uPnP setting, this tool will 'Not run' the uPnP test because it thinks there's no uPnP connectivity at all. So, evaluating this all, I think the main problem is the security restriction of Vista and your router should adapt to that, but there is ALSO a little bug in Vista or at least in that evaluation tool, because 'restricted' does not mean 'not available'.

     

    It's not so easy to send flowers over the internet, but if this helped you just leave a small message and I will know I was helpful and be happy.

     

    sincere etc,

  • Well I just bought an Acer desktop with OEM Vista Home Basic.  I'm having the same problem even though my PC is brand new.  I've never been able to get online since I got it out of the box 2 days ago.  I've tried pretty much every method mentioned in this thread, i.e. updating driver, putting in MAC address, power cycling my DSL modem, connecting directly to the modem instead of the Belkin wireless router, etc.  I'm still getting "Unidentified Network Local Only."  I'm running out of ideas here guys.  Please help. TIA.
    Friday, June 15, 2007 5:20 AM
  • I had the same problem it seems many people have been having ...  connecting to my home broadband (indeed I have 2 homes with 2 broadband connections and I had the same problem): unidentified network and local only access.

    I tried everything in these fora - assigning IP, DNS, going into registry editor to change settings, changing the security type on the wireless router, turning on or off ipV4 or 6, disabling various network connections, removing the driver and letting vista reinstall it for itself, disabling power saving and auto-sleep on the wireless adapter, etc etc.  Nothing worked.

    I should mention that I know the wireless broadband works as it has throughout this time been in use by my apple iBook and a Sony vaio running XP Professional, hence why I was convinced it was a Vista-specific problem, which in a way it was, but not with the computer...

    I then tried updating the firmware on my router, a Netgear DG834G v2 - not the latest version and not wholly supported by Netgear for Vista.  However I downloaded firmware 3.02 (the most recent for v2), uploaded it, and before the router had told me it was ready, Vista had happily found my broadband and was asking if it was a home or office network.

    I am sure this won't work for everyone but it was a very quick fix in the end and certainly worth a try!

  • I reinstalled the drivers for my Linksys router and the network problem disappeared.
    Thursday, July 12, 2007 5:46 AM
  • Check it out.  (keeping it short)

     

    I installed Vista and it installed my Ethernet connection automatically.

     

    Days passed by and i bought a Wireless Linksys USB Adapter thingy majingy.  (I HAVE NOTICED THAT) After installing this adapter, my Ethernet cable connection.. well, crapped out on me (BY MY OBSERVATION; IT IS POSSIBLE THIS MIGHTA HAPPENED RANDOMLY). 

     

    So, only the Wireless one works now.. Thank you Vista for making life hard.

     

    But i searched around and foudn this thread.. i was randomly reading through and i noticed a couple options I could TRY and see if they work.  Well, i noticed the shortest and least time consuming one, hah, good ol' laziness.  That option was..... To go to the properties of Local Area Connection, and to disable Internet Protocol Version 6 (TCP/IPv6).

     

    IT WORKED. I really hope it works for you, because this IS an ANNOYING hassle.

  • I've had similar problems since updating vista.   I purchased a Sony Vaio a few weeks ago and had no problems getting connected to my wireless network on a Belkin Pre-N router - it was a totally flawless connection except that I wasn't getting the speed I had expected.  The Vaio has a wireless N card and the Pre-N rate should be 108 - I was getting 54.

     

    After the July 12 updates, the headaches began - I have uninstalled those updates, but it didn't help.   I have been able to get limited connections after disabling the autolevel - even though it cannot be done at cmd.exe as I had previously read on another forum.

     

    I'll try some of these suggestions - had I been able to choose my OS when I purchased the Vaio it certainly wouldn't have been Vista.  Everytime a new MS OS is released, the masses end up being giunea pigs.

  • I FIGURED IT OUT!  At least for me.  I don't know if the problem for anyone else is this stupid, but I was having crazy trouble getting the laptop to connect to the Internet but my XP laptop was doing just fine.  Apparently the TCP/IP Ver. 4 defaults to a static IP -- I felt really stupid not noticing it before that the IP Address was set to something that my router wasn't even close to.  So... check the TCP/IP settings for automatically detected IP addresses ^_^

  • How i wish it was that easy for me !  (IP address)
    I struggled with this for two days before relenting and finally calling Dell   :¬(  

    Same symptoms and specs as many other people here....
    New Vista PC, was working and then orange light on router and unable to get past the NIC.
    windows reported "unidentified network".  XP machine had no probs on same router either wired or wireless.  Reinstalled NIC drivers, updated firmware on router....

    Even before booting into Vista the router had an amber light, so i assume it is a NIC H/W problem (but i'm no expert).

    Dell talked me through the usual also did some NETSH command that i wasn't familiar with, so i might look into that before taking their advice and rebuilding the pc.
    http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/netsh.mspx?mfr=true

    really annoying that i don't have a solution other than rebuilding at this stage as i'm worried it may happen again!?

    Good luck to everyone else though !
    Tuesday, July 24, 2007 9:22 AM
  • ok, well i reinstalled my pc and for a time i still had the dreaded orange light on the router... but then magically when i wasn't looking and i came back to it some time later - green!

    here's a similar forum with a possible fix at the bottom - http://help.lockergnome.com/vista/DOA-Unidentified-Network-Access-Local-ftopict22152.html -  i'm going to install the same software as before and see if i can re-create the problem, as i don't want this to happen again months down the road when i have it all setup as i like it.   So annoying..... no comments from Microsoft peeps yet that i can see.  nice

    I'm sure you've googled this problem, many people point to software installations - Norton or Dreamweaver etc.... etc...
    Wednesday, July 25, 2007 1:25 PM
  • actually, i also had the same problem...

    but i also eventually got my internet back by removing/uninstalling what i had just recently put in.

    this morning, my internet worked fine, until after i installed this nortan internet security. after removing/uninstalling that, and restarting my computer, my internet came back. =D

    hope that helps...and works.

  • I had problems with the 'Unidentified Network' message with my wired LAN connection. I found that Vista was trying to use the wrong subnet mask and this was what caused my internet access to break. I manually inputted a static IP (make sure its out of the routers dhcp range), subnet mask, default gateway and DNS info and now everything works.

    hope this helps
    Thursday, August 09, 2007 2:05 PM
  • ok im a noob at this configuring the subnet mask, inputing a static IP, default gateway and dns info...could some tell me how to do it.

    I have the exact problem as everyone else so i'll appreciate any help TIA

  • I've been following this thread for a few months now to see what issues everyone else is getting and I'm just curious (as I'm not running Vista presently), does Vista have "limited or no connectivity" or is "unidentified network" the new message for the same issues as "limited"? Resetting the Winsock (netsh etc. etc.) would make sense for fixing this issue as would McAfee and other firewall's that were potentially effecting it (as stated by someone else).

    The next time I run into this, I'll be trying a Winsock reset as I had never thought to try that before.
    Sunday, August 12, 2007 3:44 AM
  • As I haven't seen the "limited or no connectivity" message yet, I bet that "unidentified network" is the vista equivalent.  Also, if you check status, you get the same frustrating bits sent recieved:  usually < 100 or 0.

     

    I doubt that firewalls are an issue here, at least in my case.  Antivirus may be a problem, but it would be Norton & not McAfee.

     

    I have same problem with an Acer laptop that worked great for 2 hours and then LAN connection died.  To the other Acer laptop user, did you get a fix?

  • ey there

     

    i just want to ask about selecting the MAC address.

    In Device Manager, view driver details for network card, you cant see any options to select MAC and set something.

     

    Can you be more specfic.

     

    Thanks

    Friday, August 17, 2007 3:04 AM
  • To set your MAC Address:

    Once on the properties page for your network controller:

    Click on the "Advanced" tab and then "Network address."

    To the right, fill in the "Value" with a unique address.

    It should be 12 characters using hexadecimal digits (0-9 and/or A-F).

    Good luck!

  • Solution that worked for me was resetting the cable modem.  Also very weird FYI, this particular cable modem had a battery backup, which made my first attempt to reset the router totally useless until I later noticed this.  Beware of this in the future.  The cable modem was finicky and would only accept the MAC address of the first computer it saw and it needs to be reset everytime a different MAC address connects to it. 

     

    Resetting the MAC also worked.

  • I have a Netgear wireless g network that connects to my computer as multiple
    networks. one - as the ssid i set my network up as, and another as an
    unidentified network. If i disconnect from one they both go away. The
    multiple network issue causes IE not to connect.
    Refreshing the IE Page Gives the required Page.
    few days bacck everything was ok on my system
    No changes to configuration is done. this problem started coming since my nephew who got his laptop and accesssed the internet through the same netgear simultaneously on his system along with me.
    I have tried removing the "Not Preset" under advanced options of my Network adapter to the mac address it actually has.
    also tried disabling the McAfee Completely.
    The Netgear firmware should not be a problem as this is the issue which came up jest 2 days back and i ve been using netgear on my laptop with vista since 4 months now.
    it should also not be a problem with the IPv4 Address or IPv6 being enabled etc as in the threads above.
    i have not tried resetting the Netgear yet (Hardware reset)
    Wondering why microsoft is not having any solution on this forum yet. is this the issue with Vista ?

    Strangely, i was able to solve the problem. hope it doesnt re occur.

    i reset the ipaddress to get automatically in IPv4 of my wireless, but it didnt instead again gave a static ip to the adapter without a gateway address. but this solved the problem. of multiple network. but i was still not able to browse the internet so i manually inserted the ip address of my netgear wireless as the gateway to my wireless network adapter and i was able to surf the net and there is only one (the right setting) network displayed in the taskbar area.

    The problem is considered to be solved until it reouccurs (YN)

    So the solution is reset the IP Address in the IPv4 of ur wireless and set the Gateway to the IP Address of the Wireless rrouter also set the same IPaddress (IP Address of the router) as the DNS address of your Wireless network adapter. This should solve the problem.

    i spent 2 weeks to get this sorted out so just wanna share my solution with those who r really frustrated:-

     

    Dell Notebook on Vista Home premium

    2WIRE 2700HGV access point

     

    1. unable to connect or intermittent connection with the default 802.11n intel wireless adaptor

    2. ISP advised that n card might not work with the AP

    3. called Dell to replace it with a regular ABG intel card

    4. connected to wireless network but get the red X to internet. network appears as unidentified

    5. called Dell and install a patch and BAM... works

     

    did not mess with any settings, except for unchecking the IPv6 under adaptor properties and made sure the wireless channel key on the adaptor is the same as the channel on the AP. IP addresses are defaulted to automatic.

     

    note that although the n card is suppose to be downward compatible, it somehow refuse to communicate with the AP

     

    hope this helps some people out there and i will post the link to the patch soon

  • I had this happen to me on my ethernet nic, not wireless that is. It was a card on my motherboard, the solution for me after trying every other possible means was to plug in a pci nic. That sorted it out, the mb card is still useless but my other nic works fine.

  • The Only Solution that worked for me on multiple instances was resetting the Router..

    Saturday, September 08, 2007 9:59 PM
  • Try this:

     

    1. Go to Control Panel >> Network and Internet >> Network and Sharing Center

     

    2. Click 'View Status' next to the connection name.

     

    3. Clicks the 'Properties' button at the bottom.

     

    4. Highlight 'Internet Protocol Version 4 (TCP/IPv4)' and clicks 'Properties'

     

    5. In the properties dialog click 'Advanced'

     

    6. Under 'Default gateways' there will probably be a entry for '0.0.0.0'. Remove this entry.

     

    7. 'OK' out of all the property dialogs until you are at the 'Network and Sharing Center' again. The adapter will attempt to reconnect again, when it does your problem will hopefully be resolved.

     

    Cheers!

  • If what the very last person suggested doesn't work and forgive me if I haven't read every single response, you may want to turn off Windows Firewall, at least until you get connected.  I have noticed on so many occasions that Windows Firewall can keep from connecting to the Internet, at least until it is trained properly.

     

    Hope this helps.  I am speaking from personal experiences, not so much on a technical level.

  • I am using Vista Home x86. I have tried just about everything posted on various forums to try to stay connected to the network/internet, which goes out within an hour or so usually--sometimes longer. You name it, I probably tried it--including a complete factory roll-back/reinstall of Vista OS. The last one I tried a few days ago was the hotfix (KB Article Number(s): 937168) which did ziltch.

    I am reduced to shuting down, physically pulling the power cord out of the power supply for 5 seconds and restarting. Simply shutting down doesn't do it. That is the only thing that will reset the system, flush out whatever is causing it, and reconnect to my simple home network and internet (DSL modem, netgear router and Powerbook)

    I am posting this so that my "pulling the power" solution (not much of) might help someone or narrow down whats going on.

    Come on, MS!! Get your s#!t together!...Please?

    It's unbeleivable how many people have this issue, and have had for such a long time. Despite countless forums discussing this issue, I have yet to find a solution, or even seen a response from anyone at Microsoft!

     

    It is absolutely ridiculous.

  • linuxway you are a genius! You solved my problem.
    I also tried to reinstall Vista, but somehow it didn't help with the sudden Unidentified Network problem I started to experience.
    It is strange that the first time I installed Vista the network worked. Since then I upgraded the memory to 8GB and added a second CPU. It might be that having memory > 4GB caused the problem. Strange but the only explaination I can say.
    Anyway when I was ready to send the motherboard back for an alleged blown network port, your solution worked perfectly.
    Thanks!

    2. Under the Networking Tab, uncheck Internet Protocol Version 6 (TCP/IPv6)

    My wireless connection immediately reconfigured itself and connected to the net. I am thinking this could quite possibly affect wired connections as well.

    This fix worked for me.

     

    Brand new HP laptop with Vista Home installed. Out of the box refused to connect to a well used and tested network. Even Vista PC's have been connected to this network already without issue.

     

    Bit dissapointed that HP are releasing gear with this bug.

    Unplug Your Ethernet Cable From Your PC, Then Disable ALL FIREWALLS on Your PC!!!!!!!!!!!!

    DISABLE ALL FIREWALLS!!!


    Then Plug back in the ethernet cable..... and turn back on the firewalls once you are enabled on the internet Smile

    Hope I have helped anyone with future problems in this issue.

  • Hey Ryan,
    I'm also running Windows Vista Home Premium OEM 64-bit Edition and (suprise suprise) having the same problem.  The differences tho are that the onset of the problem for me was when I upgraded from 32-bit and
    its not a permanent condition, retarting the system fixes the problem for a while but long periods of inactivity (I have sleep & hybernation turned off) the problem returns.
    I just ran across these 2 links that may help, but since my computer is active athe the moment, will have to wait and see if they helped in the long run.  good luck ~@

  • Hi

    Had the same problem with the unidentified network. I was working on a public access in a small hotel. Everything worked fine so far but then we had to change one wireless router and this is where the problem started. Tried everything mentioned in this forum but no chance including all Microsoft hints and as well the hotfix. All the time unidentified network and the ip-address was always the 169.xxx.xxx.xxx. This problem tooks me hours and I am getting rid of it.

    Looking to the event viewer / windows log / system I found the error ID 1001 DHCP-Client with the following error message: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 000E2EDE6500.  The following error occurred:The object already exists.. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
    Tried to find any solution for this but no chance again.

    Back to Switzerland I tried to connect to my router and suddenly I got the same problem as I encountered in the Philippines.

    So to resume, I tried to connect to different Access Points or Wireless Routers using the network address 192.168.0.0 and I always got the DHCP-Client Error. So I changed in my router the ip address from 192.168.0.1 to 192.168.10.1 and suddenly everything works again?!?. Got a valid IP address and Windows Vista could also identifiy the network. So far no problems.

    Maybe this helps but for sure Microsoft has to work on this issue.

  • Hello,

     

    in my case, I finally resolved the problem by changing the DHCP BROADCAST flag, as described here:

     

    http://support.microsoft.com/kb/928233/en-us

     

    This resolved the problem on two brand new Vista Home Premium machines, one an HP-Pavilion m7770, the other one a Dell Inspiron 1720. The router and DCHP-server is a Zyxel Prestige 650hw.

     

    !!! Shame over Microsoft, HP, Dell and my ISP service provider !!! 

     

    I surfed in all their forums, using the key word "Unidentified Network" and "nicht identifiziertes Netwerk Vista".  I got hundreds of posts and replies with users getting crazy about this error message. Not a single of the entries contained the right link to what finally resolved my problem. It took me about a day to figure out the solution.

     

    Even the link above is not quite clear. Apart from not containing any link to the error message "Unidentified Network", it's not describing what the negative impacts of setting the flags are, nor is it clear which of the two flags should be set and how they are connected to each other. I personally set the second one only. So far everthing worked fine except that I got an error message "Duplicate IP address" on one of my DHCP clients (which disappeared after rebooting).

     

    Is this the new user-friendlyness of Vista ? It's like buying a new car, you start the engine, but it' not driving. In order to drive, you have to open the engine and fix some screws yourself, but nowhere any obvious documentation about this, unless you know the correct technical terms (in this case DHCP BROADCAST). Grrrr.... Simply terrible.

  • I had the same problem connecting wirelessly so I changed my wireless cards IP address from a fixed one to automatically and it worked.

    to do this go to Network and Sharing center then Manage wireless networks on the left panel ,select the network the click on Adapter properties followed by selecting TCP entries and make sure IP is set to automatically.

     

    Hope this helps

  • I found the resolution and it was very simple. After numerous tries and nothing working with a variety of tips, I decided to try something and it worked. I am also using calbe internet via ethernet cable. This was where my problem lied. The wireless part worked fine through my Netgear router. Resetting IP and default gateways did nothing so I decided to uninstall the driver for my ethernet adapter, rebooted and installed the driver again. Then it was able to identify my router and connected right away. Uninstall the drivers for you network adapters, reboot and re-install them again.

  • I was having this EXACT same problem... Unidentified Network, Local Access Only.

    I had purchased a new PC on Monday, and it worked fine up until Tuesday night, when it asked me to restart my computer in order to finalize the install of an automatic Windows update.  As soon as the computer had finished restarting, my internet was disabled, with the above mentioned problem.  So, after about an hour of messing with it, I turned to Google on my other PC, and found threads like this one.  I tried a lot, and nothing seemed to work, so I tried this solution posted here.

    To set your MAC Address:

    It should be 12 characters using hexadecimal digits (0-9 and/or A-F).

    Good luck!

     

    Amazingly enough, this worked for me... at first.  I just typed a random address, based on the above info, using only hexidecimal digits.  When I clicked OK, or Apply, or whatever, it said it was reidentifying my network, and boom, it was still just "Network" instead of 'HOME' (which is my workgroup's real name), but at least it now had Local and Internet access.  This worked for a while, until I was away from my computer long enough for it to go into sleep mode.

     

    As soon as I woke the computer up from sleep, it was back to "Unidentified Network, Local Access Only."  Flustered, I went back into the driver properties, and undid what I had done above, unchecking VALUE, and rechecking "Not Present."

    After I clicked apply, it reset the device, and then boom--I had Network with Local and Interent again (so here I am).

     

    This tells me one thing... the above solution was not really what fixed the problem.. it was simply the act of... resetting the network card?  This seems wrong... there's no reason this should be.  Vista has me extremely frustrated and I've only owned this PC for three days now.  I'm very close to simply reformatting, and reinstalling XP.  It seems any solution to this problem is only a temporary solution.

     

    I was also told by my brother, who setup our network in the first place, that just putting "Any 12 digit hexidecimal code for a random MAC address is not a fix of any sort, that it technically shouldn't even work, and that I shouldn't have followed that advice."

     

    Again, this only SEEMED to work, but it actually was only a temp fix, if at all.  If you ask me, and someone feel free to prove me wrong by displaying an actual CONFIRMED solution to this problem--this is Microsoft's way to get everyone to buy Vista... that Vista is simply not going to function properly on an XP Network...and that is very frustrating to myself, and I'm certain; many others.

     

    Does anyone have any response to what I posted here?  Any of the info about when the problem started, what "fixed" it, what made it come back?  It seems to be the network card is the root issue here?  Why would simply disabling it and bringing it back online, temporarily fix it?  My machine is an E-Machine model: T5246, the 2.2ghz machine.  The Network card that came preinstalled is NVIDIA nForce Networking Controller.  If I have to do something crazy like this every time I boot up my computer, just to use the internet... then I'd much rather just go back to XP.  Disappointing, really, since I had been liking Vista a lot until this problem cropped up...

    Friday, January 25, 2008 12:23 AM
  • There are five solutions so far. The first four are temporary. We will see about the last one.

     

    1st: reset router

    2nd: Change network to Private

    3rd: Re-install Nic driver

    4th: Set static IP Address

    5th: Got into router, change starting IP on the DHCP (make sure more address are avaialble than computers that need them).

     

     

    Sunday, January 27, 2008 7:57 PM
  • Hi, It's me again.  Returning to say that none of those above solutions helped me, as only resetting my LAN card works for me.  This should mean one obvious thing to anyone who knows a bit about computers--there are several problems which lead to "Unidentified Network: Local Access Only".  It is not just "one" problem, with one cause... it varies from machine to machine, user to user.

     

    I came back to follow up on what I had posted earlier, and my suspcions have been confirmed.  For me, the solution is as simple as doing this.  (This may work for you, if it all worked fine at one point, and then stopped working without warning one day.  For those who's network NEVER worked in the first place, you may want to try the other solutions)

     

    1. Start -> Control Panel

    2. Device Manager

    3. Network Adaptors

    4. Right click on your LAN Card (Mine is called NVIDA nForce Networking Controller)

    5. Pick Disable

    6. Right click on it again, and pick Enable

    7. it reidentifies the network, and gives me internet access.

     

    When the problem pops up for me.  ONLY when I allow my computer to go into sleep mode.  If I keep my computer active while I'm on it, and shut it down, I will still have internet when I turn it back on the next day.  If I leave my computer long enough to go into sleep mode, I lose internet, and have to follow the above steps.

     

    This is the solution for me, it may not be the solution to you..because as I've suggested earlier, it's becoming increasingly obvious to me that it's not just ONE simple problem that is causing this mess for everyone.  It may be a number of different things for a number of different people.  In my case, resetting the router does NOTHING, but resetting my own LAN Card fixes everything... this means for me the problem is an internal one (Very likely to be a problem with the hardware, but also just as likely to just be a problem with Vista)  For those who resetting the router works, the problem is far more likely to be of an external source, in my own opinion.  I may be wrong about this, but this is just how it feels to me.

     

    I'm very curious if anyone who has the problem crop up for them when it does for me, if my very simple and fast solution works for them.  Part of solving the problem, is indentifying where and why it came from.

  • Well, I share the pain of all involved here as I spent 8 hours over 2 days trying every one of these suggestions with negative results. One user suggested installing a new PCI ethernet card as opposed to using your cheap built in on board card. I spent $12 on a new ethernet card and in 5 minutes was RECONNECTED to my internet without fail. An easy and cheap solution. I'm not sure what the issue is, but I can tell you my Windows XP laptop worked fine compared to the Vista desktop with the problems. Lets hope the first service pack for Vista addresses this and many other issues.

  • My PC had the same problem 'Unidentified Network' just wouldn't connect to my router unless I used a WiFi Adaptor. I use a duel boot for Vista & XP & both operating systems were affected so I was able to rule those out though I did try all the usual things like deleting the network adaptors reinsalling the latest drivers. Checked the ethernet motherboard setting, tried a different router, different cable, differnt ports & much much more. It had to be a problem with motherboard or the way it was responding to the windows inviorment when it booted. After three days I got so frustrated I decided to stick an old nic card (Network interface card) into a pci slot figured it was better than using a wireless adaptor. I disabled the network adaptors in device manager before installing the nic wdows found its own drivers & I was back on line but i couldn't resist trying one more time so i pluged the cable back into the boards socket & to my surprise it identified my router straight away. So out came the nick card & restarted it & everything was working fine again.

     

    I guess the short answer is try pluging a network interface card (if you have one) into a pci slot & fire it up, once the drivers are loaded & its connected try going back to onboard devices, all I can say is it worked for me.

    Good luck!

    I honestly think this is the only TRUE solution, also.  This problem (local only) cropped up on me again last night.  My previously posted solution (Disable network adaptor, enable it) did nothing this time.  Flustered, I looked back at all the other solutions I had printed out from this thread, this time having NO luck at all.  No matter what I did, I could not get this to function.  THe best I could do was cause it to say I was connected to two networks (this is impossible, I'm only on one, and I have no wireless).

     

    Finally I gave up for the night, shut down and went to bed.  I woke up this morning intent on giving it another go, groaning and saying "here comes Local Acces annoyance again"--but to my astonishment, when I started my PC up, I saw the little blue globe that indicated I had internet access...  This flustered me, as last night I indeed tried restarting and even completly powering down my computer, neither of which worked then.

     

    It's obvious this probably isn't a Vista problem like I originally thought.  It's all NVidia Nforce Adaptor's fault... this is probably a hardware problem, a buggy network card that was likely cheaply made.  I updated the driver for my card, and now I will see how long it holds out.  If i get this problem again, I'm just going to do what Peter L C did, and replace the card itself.  Any solution here seems to be temporary at best, except doing that.. we'll see if an updated driver keeps things in order for a bit longer this time...

  • I have the exact same problem on my laptop and my desktop. My desktop is wired. My laptop is wireless and gives me the same problem at home and at school. When they wake up from sleep mode I don't have internet. There are times though when it wakes up and I have internet, but I lose it after a minute. I always see the "unidentified network" under network status. I do the same thing you do, disable the network device, wait 30 seconds, and then enable again. After that the internet is fine in all my computers.

    If someone knows a solution that would help me avoid resetting the device every time, please let me know. It is getting annoying. It is not an NVidia issue because my laptop has an intel motherboard with wireless.

  • well, as far as my problem was concerned, i did a few of things, and im not quite sure which was the solution.. but, after unchecking IPv6 from my connection, uninstalling net card drivers, reinstalling them, then a cold boot (unplug computer or remove battery, hold down power botton until all the power is drained for the 'puter, then power up) my problems have been solved.. It also seemed to me that the issue involved my computer going into hybernation mode, since this is what first caused my problems.. so under device manager, i went into my net card properties under the power management section, and unchecked "allow this computer to turn off this device to save power".. hopefully this will prevent it from happening again..
    hope this helps some of you, even though im sure it wont help you all.

  • I appear to have a simular issue.  A brand new dell XPS 420 with Trend Micro PC-cillin, Vista Home Premium and the latest Windows patches.

    From what I can tell the issue is with Toredo creating a Tunnel adapter which seems to set a default gateway that only has access to the local network.  (netstat -rn in my case shows:
    0.0.0.0 0.0.0.0 on-link 192.168.1.4 20
    0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.2 20

    Running the command (right click cmd and choose "run as administrator":
    route delete 0.0.0.0 mask 0.0.0.0  0.0.0.0

    Now in Network and Sharing Center I only see a single "Network (Private Network)" and "Unidentified Network" is gone.

    Unfortunately, after a reboot it came back.  It's at least a quick short term work-around.  Still digging....

    This is sad that a modern OS has this kind of issue out of the box.  I prefer Ubuntu (great free Linux desktop) and Mac more and more.

  • im not going to lie i just logged on here to post my problem (same as everyone else) i had tried for almost 30 hours to fix this thing including a complete reformat, changing every setting u could imagine even installing a new net work card. in the end the thing that worked for me was pulling the power cord while the computer was running, then removing the battery, and pushing the power button to free all power from the system. i put the battery back and pluged it back into the wall and then booted. i was actually happy to see the windows registration window come up because i knew that meant i was online!!! i had spent $4000 on all these parts while i was deployed and was about to set it on fire, it was my first water cooled build and i had ran into problem after problem, im glad i can finally use the computer in the full capacity.

     

    i hope this helps cause i know how horrible this problem is.

    Hi, It's me again.  Returning to say that none of those above solutions helped me, as only resetting my LAN card works for me.  This should mean one obvious thing to anyone who knows a bit about computers--there are several problems which lead to "Unidentified Network: Local Access Only".  It is not just "one" problem, with one cause... it varies from machine to machine, user to user.

     

    I came back to follow up on what I had posted earlier, and my suspcions have been confirmed.  For me, the solution is as simple as doing this.  (This may work for you, if it all worked fine at one point, and then stopped working without warning one day.  For those who's network NEVER worked in the first place, you may want to try the other solutions)

     

    1. Start -> Control Panel

    2. Device Manager

    3. Network Adaptors

    4. Right click on your LAN Card (Mine is called NVIDA nForce Networking Controller)

    5. Pick Disable

    6. Right click on it again, and pick Enable

    7. it reidentifies the network, and gives me internet access.

     

     

    VistaNetworkProblem, this worked for me too. Thanks a lot for posting it, this "unidentified network" *** was driving me absolutely crazy.

    Thanks again! as well as to the others contributing to solve this annoying problem.

  • im have a very similar problem...New Acer desktop and network dramas.....but i have sometimes have 2 networks. local and unidentified.(dont know where the 2nd one is from. Just popped up 1 day) im think my problem could be caused by driver. but really unsure and dont wanna fiddle 2much and kill computer more!
    if u find any good info can u pass it on2 me and i will do the same....

  • I'm having the same problem with Vista Ultimate x64 SP1 and a Dynex DX-E401 wired router.  I can get it to work eventually, but unfortunately the jack in my wall is acting up and the slightest bump disconnects it, so then when I unplug it and plug it back in to get it back, I have to go through this whole damn process all over again.  I would imagine the official cause of the problem is the DHCP Broadcast Flag defaulting to being set in Vista and some older routers not supporting this, however even setting DhcpConnForceBroadcastFlag to 0 in the registry for my network adapter GUID has not fixed this problem consistently, so I don't know what else to try.  I usually have to unplug and plug back in the cable about 10-20 times, getting the unidentified network message every time, before getting a successful connection once.  So it's not even consistent, it just doesn't work for about 90% of connection attempts.  But once it's connected it's fine until it gets disconnected for some other reason (in my case, the stupid wall jack).  It also seems that "reasserting" the broadcast flag to 0 helps, i.e., going into the registry, changing it to 1, and then changing it back to 0, increases the chances it'll work on my next attempt.

     

    This is so freaking aggravating and this ALONE is making me hate Vista.

  • K guys seriously.
    You're gonna kick yourselves, hopefully it works all around.

    Working for tech support I have found multiple times this solution has worked:

    Shut down the computer.
    Unplug the power cable (even on laptops this should work)
    Leave your computer for 5 minutes (no less!)
    Turn it back on
    Enjoy the internet!



    We have used this many times over, haven't heard of it failing yet (no guarentees though, of course).

  • Hi all,

     

    Sorry for the lengthy post, but just wanted to add my experience of these issues...

     

    I work for a small company and last year we bought 6 new Dell laptops with Vista Business 32-bit. All have been experiencing the problem where the network (LAN or WAN) shows as "unidentified network" after waking from Sleep mode.

     

    This can be at home, in work, or out at client sites. So it's not an issue with a particular type of router or hub. As I said all the laptops show the same issue, so surely it can't be faulty hardware? The wireless adapter is an Intel-4965AGN, and the LAN adapter is a Broadcom-NetXtreme, so it's not an issue with a particular chip manufacturer.

     

    I agree with an earlier post that the "unidentified network" is just an all too common symptom of various problems between Vista / NIC drivers / external network devices, and therefore probably won't have a single solution. For us, the only work-around is to disable then re-enable the adapter. Obviously rebooting the laptop, removing the cable for 5 mins, changing adapter settings etc will have the same effect. However as well as being a total pain, this is a WORK-AROUND, not a solution as some people seem to think. Typical helpdesk mentality - rebooting may restore connectivity, but it doesn't resolve the issue! This is basic functionality for a PC or laptop, and we simply shouldn't have to do this.

     

    We've tried new NIC drivers from MS, Dell, Intel and Broadcom. We've tried various Vista patches & tweaks - most of which have been mentioned above already. We've even tried some suggestions that were obviously not relevant to us, for example the DHCP Broadcast setting (Note: this can't be a DHCP issue for us, since an adapter doesn't stop working just because it can't speak to its DHCP server - it just continues to use it's allocated address). DHCP errors are symptoms rather than the underlying issue, since we get the same with static, DHCP, or reserved DHCP addresses. Some of us have upgraded to Vista SP1 (resulting in several new issues e.g. with VPN access), but all to no avail.

     

    I've now rebuilt my laptop dual-boot XP and Vista. I've been using XP on it for about 2 weeks now, with no sign of the problem. Unfortunately, this isn't an option for some of my colleagues. However, I think it does point to the probable culprit being Vista itself, or the combination of Vista on a Dell laptop.

     

    IMHO, if you want a single "solution" to these issues - go back to XP, and let others pay for the privilege of doing live Beta testing for MS.

  • I have has this same problem with my Acer Laptop and I have figured out the solution.

    This only happens when I bring my system back from "Sleep" or "Standby" mode. My remedy used to be doing a "route delete 0.0.0.0" then a release and renew of my IP address.

    However, I found that if you add a DWORD key it solves the problem.
    HKLM\System\CurrentControlSet\Services\CSC\parameters
    Create a DWord Key called "FormatDatabase"
    Set value to "0x00000001"

    being in the it world getting a 169 ip is common... try this,

     

    unplug the coax cable, repair the connection if it pulls 192.168.100.x replug the coax and repair the connection again, you should be able to get online after that

  • Hi, Yesterday i woke my computer from sleep mode and to my surprise i had no internet connection, i checked the Network Connections and Network Sharing Center and instead of displaying my router name, it just said "Unidentified Network" and Access Local only.

    I rarely ever have my computer in sleep mode as i usually shut down if i know im away for 3 or so hours but this has never happened to me before. I did some research only but to only come up with a ton of work arounds and fixes and such which i have got lost in.

    I have Wndows Vista Ultimate 64-bit Edition OEM, i can connect fine to my router using my Netgear Wireless PCI Adapter WG311T, but when i use my Wired Connection all i get in Local Area Connection 1 & 2 is
    "Unidentified Network" i see that i am not the only person to have had this problem but i've spent the last day searching for answers to fix this problem or work around it so i can finally use my Wired Connection again.

    I have tried a couple of things that people said could work but to no avail.

    Any help would be greatly appreciated Thank You!

  • I have found the following solution to the "unidentified network" problem.  It may work for you or it may not.  I am using Vista with no other computers connected to my desktop.  Often while I am on line the "unidentified network" problem would appear out of nowhere and I would loose my connection to the internet.  After talking with my ISP and several other tech support type people, I didn't get any help.  The steps here I think may help.  I have done this and have had no problem now for over two weeks. 

    1.     Go to the control panel
    2.     Click on "network and sharing"  This will bring up a window that shows   
            your connection to the internet.  

    3       In the left pane on the window, click on "Manage Network Connections."
             This will bring up a window that show all the networks active on your
             computer.   You should see the " unidentified network" in this window.
             If there are two networks with the same name, ie "Intel(R) 655883 DC
             Gigabit Network Connection" and there should be then you should
             right click on one of them and delete it.

    4       After you have deleted the "unidentified network" then right click
             on the remaining network and RENAME THIS CONNECTION.
             You can rename it anything you want.  ie.. Bills Bedroom or Marys
             Kitchen.  
     
    5       After renaming the network connection, close and restart your
             computer.  This should solve the problem.  It has worked for me but
             I am only using one computer.  Good Luck.

  • I have been having this "unidentified network" problem for some time.  I have called everybody I could think of including president Bush.   No one seems to have the answer to this problem.  I took it upon myself to solve the problem.  I think I have found the solution that might work.  It has worked for me so maybe it will work for you too.  Here are the steps I have taken to fix this problem

    1.        Go to the control panel and click on "Network and Sharing Center".
                       (this will bring up the window that shows your network
                        connection).

    2.        In the left window pane,  click on "Manage network connections".
                   ( this will bring up a window that shows the internet connections
                      on your computer.  There should be two connections and they
                      will both say the same think.

                           Example:  "Intel(R) 785562DC 2 Gigabit Network Connection"

    3         Right click on the connection to the right and RENAME it.
                          ( you can rename it anything you want.  ie.   Bills Bedroom or
                              Marys Kitchen).  whatever.

    4.       After renaming the right one,  delete the other connection.  Then close
               everything and restart your computer.

    I have tried this and have had no problem now for over three weeks.  It seems to have solved the problem for me but I am only using one computer.  I have no other network computers with my setup.  Also it seems to me that the internet connection will not work without a name.  Good luck.

  • I tried everything posted here including a vista reinstall and switching to another hard drive. Nothing worked. Then I tried turning off the computer unplugging it and removing the motherboard battery. I plugged in all back in and it worked! This seems to be the most common working fix. I don't want to say it will work for everybody but if you haven't tried it give it a go. It worked for me. Thanks to all who posted this fix!

  • Hi,

     

    Here's a short account of my situation and problems, and then the solutions that worked for me.

     

    A few weeks ago, I bought an Acer laptop with Vista. At the start, wireless connection as well as wired internet connection at my working place functioned well, but at home (with home pna) I had no connection, 'unidentified network' on display. Then I downloaded Service Pack 1 for Vista. Result: no more internet connection and 'unidentified network' on display, now both at home and at work, both wired or wireless. I tried everything described in this forum, without positive result.

     

    Now, together with a friend, I found a solution that worked for me:

     

    1. we uninstalled vista service pack 1 (back to restore point before sp1 installation). Now I had internet connection again at work. At home still 'unidentified network'.

     

    2. we applied the advice described here, at the bottom, under 'more information' (we changed data value from 1 to 0):

    http://support.microsoft.com/kb/928233/en-us

    Now I have internet connection at home also, no more 'unidentified network'.

     

    Maybe this might help some others as well.

    Best, Freddy18

  • Lime many, I also had a Unidentified Network problem. I did not have wireless connections, they are all wired. I run 3 computers on my home network, 2 vista home premium x64, and one XP home x32. However in my case one of my vista machines was having a checksum error.

    With that, all I did was change out the checksum battery on the motherboard with an old battery from a spare computer in the closet. In my case the battery was coin shaped.

    But back to the problem. Because of this faulty battery, my computer would not run or recognize the network adapters or their services.

    So being similar, perhaps changing the battery on your motherboards will fix the problem. I don't know for sure, it just worked for me.
    Sunday, September 28, 2008 2:48 AM
  • All i can say is you ROCK!

     

    After dealing with this problem for days I was at my wits end.

     

    I uninstalled lan adapters and pull the plug on the machine.  pulled battery...

    then pulled some hair out  held power button in for a minute.

     

    rebooted in safe mode with networking.... and   and   and..........

     

    Connected to network 2 and internet

     

    Thank you, thank you thank you.

     

    I'd send you a starbucks card if I could.

     

    Thanks,

  • Many Thanks.

    I have had the same problem, My system went to sleep before I had a chance to change the power settings on a new install. The only programs I had installed was Office 2007 & Adobe Acobat Reader 9.0. I left the room and came back and the system had gone to sleep when I hit the space bar to bring it back I noticed the internet was not working.

     

     I have tried lots of basic things but what really worried me was I have this install on a new hard drive and my old install on another one so I can transfer everything accross, so one thing I tried was booting off my old working install but the problem was still present ( I had never gone into sleep mode on old install ) even though it was working the day before.

     

    Thanks to who ever found the turn off and remove the CMOS Battery as this fixed it straight away. Bringing to a close two very aggrivating days pulling my hair out.

     

    Thanks again

  • Tried various suggestions.  Simply roll back your system via System Restore to the day (or earliest date) before the issue occured.  Unable to pin point a reason as to why but it is certainly Vista related.

  • Hi,
    I had this issues too,
    and after searching for two days , finally get the solution :)
    it was a problem with Norton Anti-virus when I uninstall it, and the solution as it posted:
    "I had the same "unidentified network-local access only" problem after removing Norton Anti-virus. The issue turned out to be that the regular Windows unistall doesn't fully get rid of it. You need to run Norton's own removal utility: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2005033108162039 "


    Hope this helps,

  • Over 12 hours and have tried every thing!
    The only thing that works for me was putting a value for network card instead of "not present" but THAT VALUE WILL BE THAT COLLECTED BY USING "IPCONFIG /ALL"  WIRELESS CARD NETWORK ADDRESS AND NOT OTHER. 

    Restore all firewall settings to defaults in WINDOWS LIVE ONE  if it is installed or in Windows Firewall to factory defaults. 



    THEN I GOT THE SUCCEFULLY CONECTED HAPPY MESSAGE.
    HOPE THIS HELPS.
    THANKS.

  • unidentified network - the (re)solution   (< this is a searchstring for many frustrated Vista users)

     

    You probably have a router that's about 3 to 4  years old, it supports 100T and you see no reason to replace it. You have upgraded the firmware to a version that officially supports XP, but there is no official Vista-supporting firmware version (yet).

    Well, that's my situation. The new firmware version shows in the settings (under the chapter NATP) a tab about uPnP that was not there before, or at least in don't remember it. These uPnP settings allow me to choose 'Full uPnP' /  'Secure uPnP'  /  'No uPnP'.  It is by default set to 'Full uPnP' and that is with high probability an XP compatible setting. The thing is that Vista apparently requires a more restricted setting, otherwise it will not allow you to connect to internet. After changing this setting to 'Secure uPnP', 90% of my problems vanished - restarting my pc brings me to the LAN and internet rightaway, though resetting my router brings me to LAN rightaway but not the internet (showing an 'X'). One repair of the internet 'X' brings me to the internet in 1 second. Wow, that's a progress really. (So, do not reset the router, no problem heh?)

     

    Moreover, my network-setting of 'private' is really remembered now, as is the 'network discovery' setting. This latter has been turned off manually all the time, because it influencs your firewall settings. I still have to test that in the new settings. Firewall is off through group policy (dos-box: secpol) because that's what my router is supposed to do and is doing very very well too.

     

    You should search for Microsoft's 'Internet Connectivity Evaluation Tool'. This tool evaluated my router as fully compatible EXCEPT for uPnP compatibility. After changing the router uPnP setting, this tool will 'Not run' the uPnP test because it thinks there's no uPnP connectivity at all. So, evaluating this all, I think the main problem is the security restriction of Vista and your router should adapt to that, but there is ALSO a little bug in Vista or at least in that evaluation tool, because 'restricted' does not mean 'not available'.

     

    It's not so easy to send flowers over the internet, but if this helped you just leave a small message and I will know I was helpful and be happy.

     

    sincere etc,

    sjet

     

    Hi.. I've had LOADS of systems recently with this problem. Not an ideal sollution, but I disable uPnP in the router and this usually solves the problem.

    This post put me on the right track.. cheers.

  • Hi all - I tried everything mentioned in this post and on other forums to solve this problem.  Nothing worked.  

    In the end the thing fixed it was to disable the on-board network (nForce4 chipset). I then added another old network card in that I had spare and that worked straight away.  All "Unidentified Network" problems gone.

    I don't know what went so wrong with the nForce networking on the motherboard (A8N-E) as it had been working fine for many years. 

    The only thing that could have caused this drama was installing Apple's Airport Utility but it seemed to work OK after that was installed - for a few hours at least.  Removing Airport/Bonjour does not fix the problem anyway.

    I should mention that I am using Windows 7 RC which seems to have the same networking issues as Vista.

    Cheers

  • Well here and update. i have had this problem 2 times now and the most recent on was my Anit-virus had expired no worrys i was going to renew it. but figured i would blow the dust off the computers... disconnected the computers reconnect them  and what would you know one would connect one would not  both running vista. after countless hours of doing everything under the sun i uninstalled my anit-virus and BAM connection to the internet came up. so if you have an expired anit-virus it might be blocking you. al tho i dont know why it was doing this on on computer and not the other

  • I am using Vista Home x86. I have tried just about everything posted on various forums to try to stay connected to the network/internet, which goes out within an hour or so usually--sometimes longer. You name it, I probably tried it--including a complete factory roll-back/reinstall of Vista OS. The last one I tried a few days ago was the hotfix (KB Article Number(s): 937168) which did ziltch.

    I am reduced to shuting down, physically pulling the power cord out of the power supply for 5 seconds and restarting. Simply shutting down doesn't do it. That is the only thing that will reset the system, flush out whatever is causing it, and reconnect to my simple home network and internet (DSL modem, netgear router and Powerbook)

    I am posting this so that my "pulling the power" solution (not much of) might help someone or narrow down whats going on.

    Come on, MS!! Get your s#!t together!...Please?

    Thank you! Woke up today, on Halloween, and internet on my main computer had mysteriously stopped with the unidentified network local connection only problem.
    I tried everything listed above, was beginning to believe I'd never get it working. Was considering going back to a previous backup to see if that helped. The only thing that worked was:

    Unplug the power cable at the back of the problematic computer, and wait until all the lights are off. (I was waiting for the green light glowing from my ethernet socket especially, easy to see since its now dark and I've been trying all day to fix computer).

    I had unplugged the router for a few minutes too, but I'd done that lots of times during the day, the first time I simply tried unplugging the power cable, and it worked!


    Obviously some erroneous data was being remembered by the computer, that wasnt being removed by a simple shutdown. Definitely the computer at fault, I'd unplugged and changed to a different ethernet cable to see if that helped, and my XBOX and other computer connected to Internet fine (luckily, else I wouldn't be able to come on here and look for solutions.)

    Someone should make a short list of all the solutions that worked as above.

    The IPV6 solution, the MAC address solution, etc, and of course...

    Unplug the power cable at the back of the problematic computer, and wait until all the lights at the back are off.

    It worked for me. Thanks very much.

  • It's quite easy to fix this. 
    -Open Device Mgr
    -Disable the driver
    -uninstall it
    -Enable it and win7 will search for it and hey, the original driver is installed.

  • Solved.  "Unidentified Network" error

    Hi, thanks for this thread.. I have:

    Vista x64 ultimate
    Asus L1n64-sli ws 
    2x AMD fx-74 procs
    4gb corsair 800mhz ram
    evga 8800gtx superclocked


    I tried everything on this thread, and none of it worked.  In my frustration, I began beating my old computer and a Realtek NIC fell out.. I put it into my current pc, booted, and viola, I had network connectivity again.  It turns out that both ports for my onboard NIC were shot, or the onboard NIC itself was shot... either way, putting in a card did the trick.

    Good luck

  • This is a very simple software proble. U remove IP6 or fix it with DhcpConnEnableBcastFlagToggle.. nothing will seve u the purpose. Just diable ur firewall or remove firewall from system.. particularly mcafee firewall. it will run great.

    Donot strain urself on other installing or renwing or resetting.. just disable or uninstall mcafeee firewall.. it works with flying colours

  • I'm having the same problem with my HP Pavilion dv9000.  Unidentified Network...  Funny thing is it won't work anywhere.  I actually sold it to a friend of mine only to find out that he also could not get on the internet (was thinking it just didn't like my router).  Normally I would just format after having so much hassle but that doesn't seem to be a option as attempting to do so my computer doesn't seem to even detect a harddrive...at least not until windows start.

    I have tried everything that has been said here and nothing is working.  If it was still my laptop I would just smash it...

  • I recently re-located my computer from underneath my desk to on top of it.  Although it was working perfectly before, when I hooked all the cables back up again, much to my dismay, I was no longer able to connect to my home network.  I tried all of the standard renew/release IP diagnostics, and ran the configuration tests, and nothing worked.  I am baffled that simply unhooking my network cable, then re-connecting it could cause such a problem.  I will walk through the steps I have taken to try and solve the problem, and welcome any feedback or solutions on the matter.

    1.  I disconnected the ethernet cable from my PC and connected it to my laptop (which I'm using now) to make sure that the cable wasn't my problem.  I disabled the WiFi adaptor on the laptop, and was able to connect to the network and internet using the ethernet cable.  (ruling out the cable as my problem)

    2.  I reconnected the ethernet cable to my PC, disabled my LAN adaptor, re-enabled it, and watched the status go from 'Identifying. . .' to 'Unidentified Network'.  So, I ran the network diagnostic tool, and it gave me three options .  'Automatically get new IP settings' which did not solve the problem.  'Reset your router' which also did not work.  And 'reset the LAN adaptor' which didn't work either.

    3.  Used my laptop to download the new driver for my LAN adaptor, burn it to disc, install it on my PC, then update my driver.  Problem is still not solved.

    4.  Starting to get desparate, I disabled Windows Firewall, reset my LAN adaptor, and I was still receiving the 'Unidentified Network' message. 

    5.  Re-enabled firewall, changed network settings to Private, from Public (which it was defaulting me to), turned off all file sharing and reset the LAN adaptor again.  Still got the 'Unidentified Network' message.

    6.  I went into the Properties menu of my LAN adaptor, and looked at what it had for an IP address. . . To my surprize, it was getting 169.254.90.121, with a subnet mask of 255.255.0.0.  I do not know if this is window's default IP address when it can't connect to anything, but what I should have seen, had it been working properly was 192.168.1.64, subnet mask 255.255.255.0.  So now clearly, something is stopping my LAN adaptor from communicating with my router.

    7.  Call MS Tech support. . .They can't help me.  Well, they can't help me for FREE.  Turns out because I bought the OEM version of Vista I have to pay for tech support.  Fortunately, the Techie from MS was nice enough to give me this piece of free advice. . . 'call your ISP'.

    8.  Called my ISP, repeated steps 1 - 6.  Banged head on desk. 

    9.  Visually inspected my router, and noticed that the port that my PC was connected to IS indeed lit up, showing that it knew something was there.

    10.  Used the laptop to access the router's configurator, and did not see my PC as an active connection.

    11.  Lost all hope.

    This has been a really frustrating problem because everything WAS working properly until I unplugged all of the connections from the back of my computer, then re-connected them all 10 mins later.  I have read through most of the posts on networking problems, and couldn't find any answers, so I'm starting a new post in hopes of finding one.

    My vitals are:

    O/S: Windows Vista Home Premium OEM 64-bit Edition

    Processor:  AMD Athlon 64 3200+

    M/B: Gigabyte K8 Triton K8T890

    LAN Adaptor: Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller

    LAN Adaptor Driver: 9.16.2.3

    Modem/Router: 2wire 2700HG-E Gateway combo unit provided by Telus

    Any help would be greatly appreciated.  Thank you.


    I think an easy way is when you start up windows 7, don't log in yet, let the HD run for a while like one minutes until the light on you modem stop flashing repidly, and then log in to windows, it works for me.  I use to log in at once and always have the same problem that my network will not work and I have to disable it and enable it again to get it going.  Hope his helps.

  • I have windows vista on a HP laptop. I have windows 7 on another HP laptop. with a brand new Netgear routher. the ethernet works on both, but only the windows 7 laptop works on wireless. the one with windows vista says ( UNIDENTIFIED NETWORK ), So this is what I did...........

    Well I had the same prob, nothing worked, I tried almost all the things you all said, fanally I unpluged my brand new Netgear router I had just bought two days ago and I bought the exact same router. took it home and hooked it up and now It works well. no more unidentified network, it works through the ethernet as well as wireless. so It may be you just have a flaw in your router. mine was brand new and it still was bad, you never know.

    I hope that works for you, it is the only thing that worked for me.

  • Make sure your router firmware is up-to-date.  We upgrade all the drivers in our PC for Windows 7 but forget to upgrade the router firmware.  I upgraded my router firmware and all those unidentified network problems went away.  It is much easier than forcing windows 7 to work with an out-dated router firmware.  I wish this forgotten upgrade of the router is promulgated by Microsoft.   Consequently many of us wasted a lot of time on this one.

  • I've had this same problem and I tried everything in the world to fix this.  The easiest thing to do is upgrade to windows 7 or go to a mac.  Vista is terrible and will make you grow gray hair before you find out what is wrong.

     

    As soon as I installed windows 7 my problem was fixed.  Microsoft you did us terribly wrong by creating VISTA.

  • Before trying all this regedit changing you need to update your drivers.

    Driver for adapter is out of date on HP & Microsoft Update Pages. Finally found program that is free to use here is web site http://www.innovative-sol.com/drivermax/ for those with local only connection on wireless. Fixed my local only problem. I would just make sure you get only digitally signed drivers they worked best for me.

    I have tried every thing in almost every blog and help sites assists I have read for the last month with no luck. Removed all my security & anti virus even used the special removal tools no luck till I found this free Driver Program.  

    Give it a try and Good luck to everyone else with this same problem.

  • Tom Milligan,

    Out of the past (it's 2010 now) you rescued me.  Just bought brand new Linksys E2000 wireless/wired router, had Vista "unidentified network" problem, spent hours trying dozens of interweb suggestions.  Finally saw your post, and downloaded new firmware (on a different machine!), and updated the router.  Immediately, my desktop PC came alive with a full-speed connection.  THANK YOU!

     

    Details:

    Windows Vista (sux) latest patches

    Brand new Linksys E2000 router, connected via Ethernet cable (not wireless)

    Connection won't work, Vista networking center says "unidentified connection."  Linksys "help" people suggest that I set the connection speed to 10MBPS half-duplex (which enables the connection, but the download speed is so slow as to be unusable). 

    Upgrading firmware fixes the problem.

  • HP dv2810us

    Unidentified network issue on Ethernet only, wireless fine.

    Solution: Update BIOS to latest revision

     

    I specifically made an account just so i could post this, so many google hits on this but the solutions didn't work until I flashed the BIOS.

  • Where is firmware ie if I go into All Programs is it in a particular file with the Netgear.  I am no computor expert but this is driving me mad!  Any chance of a step by step guide?  Would be much appreciated.

  • read just about all of these options. I did the manual input of server dns and ip address, it recognised as network instead of unidentified. i disabled all firewalls, including norton. i have had trouble with norton b4, it is an absolute beast!! i downloaded norton removal tool from their website and flushed my pc completely, suprise suprise it now works!!! a lot of pcs come with free trial of norton, when you uninstall it, it never works!! have had so much trouble on other pcs with norton. go to website and get removal tool. i had a hp sr2125uk running windows vista.
