Wireless network not working after Sleep

    General discussion

  • Hi All,

    My wireless network does not work and even the worse, it does not even get listed in the Available Networks after a Sleep. I have to restart my computer to get connected to my wireless network. I am not sure how to troubleshoot this issue.

    May be its my nVidia Video Card creating problems? - My video card -  NVidia GeForce 9800 GT (Prerelease - WDDM 1.1)

  • Windows always had problems with sleep, mostly with nvidia drivers, i have the same as you in a Dell XPS 630i and my mouse was froxen most of the time after i got out of sleep caused by the nvidia drivers.

    With windows 7 i put it to sleep 4 times without problems, if you do a "sigverif" it will give you the drivers causing problems.

  • Your video card has nothing to do with this.  It is likely your network card drivers that are having a tizzy fit when windows comes back from stand by mode.  My daughter has a Dell Inspiron 1525 and the Dell wireless card every since I updated my router's firmware to support WPA2, will now lose it's connection after returning from stand by or hibernation. 

    My other two notebooks are running Windows 7, one has a Linksys Wireless WPC54G card and it does not have the issue, the other is and HP notebook with a Intel  Wireless WiFi Link 4965AG, and it does not have any issues with the stand by recovery or hibernation as well.

    I would check to make sure you have a current driver for the wireless card, or at least check through the change logs or release notes on other releases of drivers for your card to see if anything like that is mentioned.

  • I have the same problem on an Alienware 5900.  It also occurs on the Vista install I had on there previously (even though Alienware claims it's "Certified for Vista" - that's a farce).

    I have the latest network drivers installed.  I'm not sure where the problem lies (though my guess is Alienware/Dell's lack of driver support), but one thing is clear - the upgrade to Windows 7 didn't solve any issues I have with the laptop (if anything, the upgrade has introduced more problems).

  • Having the same problem on my home-built tower, but with ethernet connection, not wireless. And when I try to restart, the computer hangs at "Shutting Down" message, so that I have to manually press the restart button on my box. Once restarted, all is well until next standby.

    My machine:

    M/board; Asus P5KPL-CM
    2GIGs DDR800 ram
    Nvidia 8600 Graphic card
    CPU:Intel E8400.
    Dual-boot system with Windows XP Service Pack 3.

  • Please run Windows Update and confirm that you are running the latest updates for your wireless network adapters. If you have the latest updates and you are still seeing problems, please reply with:

         --- make/model of the Wi-Fi card. You can get this by typing "netsh wlan sho dr" on the command prompt
         ----make/model of your Wi-Fi router
         --- problem symptoms
         --- reproduction steps for problem to happen

  • Hi Alok,

    I have the same problem on a wired connection. Here's my details:

    NIC card is: Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller (NDIS6.20)
    This is the onboard NIC for my ASUS M4A78-E Motherboard

    Router is: DLINK DIR-628

    Symptoms and how to re-produce: When I let my PC go to sleep from Inactivity or Hibernate, the network connection shows a red X. When I try to re-enable, it shows limited connectivity and a PC restart does not fix this. I have to manually disable and re-enable the NIC card to allow this to work.

    Thanks for your help.

  • Hi Alok,

    Same problem on a wired and wireless connection. Installed the latest updates from Microsoft.

    Intel Pro/Wireless 3945ABG Network connection
    Linksys G ADSL Gateway 
    Model: WAG5AG V3

    Preety much close lid, turn computer on sleep and it will not connect to my wireless network. I have changed power management settings in network driver, i have ensured I have the latest software and it still keeps happening. I use to be able to re-start my computer and have the internet working again (until I put it to sleep or close the lid) however it will not even connect at all. When I try to connect and use troubleshoot it identifies it as a "Network Adaptor" issue. 

    Currently using the RC version of Windows 7. On Beta I was able to disable my wireless when it went to sleep and be able to re-enable the wireless and connect to the internet -No Probs- but RC doesnt even work at all.  

    Thanks for your help!

  • Hey everyone!
    I have the same problem. My computer is a notebook Dell XPS 1530, my wlan is a Mini-PCI 1395 Dell, Windows7 Ultimate 64bits, and the router i think is not important because i had the same problem with a least 3 diferents(netgear router, linksys router, linksys Acces Point), and with diferents types of security (WPa2, WPA, not at all, etc).
    I tried to update my drivers, but i got the same problem, and Windows Update is running always, and I manually check for updates but nothing really helps
    Everytime my notebook goes to sleep, i have to restart to get internet conection again...
    I hope somebody can help me
    (PS: Sorry, i'm from Costa Rica, so my english isn't good)
    Thanks in advance

  • Folks, those of you having wireless issues please cut and paste the output of the below command:
    netsh wlan show driver

    This will tell us the NIC and driver information so we can determine if you have the best driver for your device.

    For those of you having problems with Wired devices please share:
    LAN device name:
    LAN device PNPID:
    LAN device driver version:
    LAN device driver date:

    Thanks,

  • Hi,

    here's another case on Build 7100/64. CPU is Intel E8400 dual core. I'm running a brand new "Linksys Wireless-G PCI Adapter" which can't reconnect after a Sleep or Hibernate cycle. It may have started once, but on the 3 other trials I've had to restart the computer. Clicking on the WLAN bars and its sub-menus, or doing a disable-enable cycle of the board doesn't bring it back on line.

    Borge


    I hope this helps:

  • Hi, I had the same problem and tried many solutions. As a last resort I uninstalled and reinstalled my wireless adapter; strangely enough it now seems to come out of sleep (and hibernate) with working wireless connection. (Win7 RC 64). //Stefan

  • Hey folks:
    My problem with the wireless seems to be solved by some windows update i didn't remember.
    Nothing else I did, so it must be the WU.
    So guys, turn on WindowsUpdate and wait to be online again, after the sleep
    Thursday, July 02, 2009 5:31 PM
  • Windows Update didn't fix it for me so doesn't look like that's it. However, if you go into the "Wireless Network Connection Properties", click "Configure" to bring up your adapter properties, and switch to the "Power Management" tab, you can disable the option to "Allow the computer to turn off this device to save power". This fixed the issue for me. Although it would be nice to save power, it's much more of a hassle to not be able to use your wireless adapter when you return from Standby. Hope this helps someone else!

    Cheers!

  • Alok,

    I have a HP laptop - model DV6408nr running Windows 7 build 7100.
    When it goes into time-out sleep mode, it wakes up with a "Limited Access" star on my wifi connection.
    Disabling / enabling doesn't fix it. Uninstalling driver / adding new device doesn't fix it.
    Rebooting is the only way to correct the problem, until it wakes from sleep mode again....  Might as well
    just shut itself down for me at this point...

    I have a security "grace period" set between screen-off and password wake requirement. If it wakes up before
    it needs a password entered, wifi works. If I have to enter a password, it doesn't work.

    Updating drivers did not help. Going back to original MS autodetect-driver worked for a couple of days.
    I think it autoupdated to a newer driver, and it stopped working. Uninstalling / redetecting no longer
    fixes the problem.

  • still working after a time-out sleep mode too... This is NOT the original driver...  search for the driver # above on this site...
    Friday, August 07, 2009 8:08 PM
  • Have a similar issue with my hspa dial up,when the modem goes in stand by mode and if i try to connect to other site that is not the same im in currently,the page will not be found and the destiny is unreacheble but the trick i use every time my modem goes sleep when im reading or typing and i want to go to another web site i just use the current site to wake the modem and then i visit other sites which sucks i wish that never happened...
    Regards,

  • Old driver trick worked for coming out of sleep mode, but it started dropping my connection at random other times. So, I'm back to current driver and rebooting to get on the internet :(

    Refresh current page trick doesn't work for me either...

  • telarc,

    I don't know if you saw my post, but try disabling the option to "Allow the computer to turn off this device to save power" on your wireless network adapter. The reason why mine wasn't working is because sleep mode was turning off my device and then coming out of sleep mode wasn't properly turning the adapter back on.

  • Mine is unchecked since i installed the modem but for some reason it keeps going to a nap...
    but that in my case which im 100% sure my modem has been modified and its bugged...

  • My new Dell desktop 1545s has the exact same problem as yours. Did you ever solve the problem? It is frustrating to have to restart every time after sleep to get back on the Internet.
    Saturday, December 12, 2009 3:36 AM
  • ok everyone, stop freaking out!!! I found a solution . Anyways, this is not the problem of ur wireless card OR windows 7. Its just a feature that shouldnt rele be a feature. Anyways to fix this problem,

    Step 1: Click on Start and go to Control Panel. In the Control Panel, Click on Small Icons to VIEW.

    Step 2: Find Network and Sharing Center and open it.

    Step 3: On the left side, you will see an option that says "Change adapter settings". Open it

    Step 4: You will two connections there, local and wireless. Right Click on WIRELESS one and select properties.

    Step 5: Now Click on CONFIGURE.

    Step 6: You will see 5 tabs, click on the last one that says "power management"

    Step 7: Now simply UNCHECK the first box that says "Allow the computer to turn off this device to save power"

    Thats it, you are done. NOW you can do whatever you want, put it to sleep, stand by, hibernate ... and yea you wont have a problem anymore :)

    I bet this will fix your problem so you are WELCOME :p

  • I did what you said and my computer was already unchecked at the power mamagement box you suggested. Upon waking from sleep the adaptor was unconnected. Now I just HIBERNATE instead of sleep and no more disconnects so far. Gave up trying to fix the Sleep, At least for now, gled you got yours to work.

  • I also had this with my Centrino notebook and the Windows 7 RTM. After installing the latest updates from WU, the issue is gone.

  • Please read the entire post before commenting.  This solution has been repeated and has failed multiple times.

  • PROBLEM FIXED - for me at least. I had the same problem for some time and have tried various forums to find a fix. I am using Windows 7 Home Editon 64 bit with a Realtech RTL8191SE wireless card which would not reconnect to my wireless network after Sleep mode. My problem is now fixed by going direct to the Realtech website and downloading the latest driver, the WindowsUpdate always showed my driver as being up to date, which evidently was not the case, prior to going direct to Realtech. So my recommendation is find out exactly what wireless card you are using and then going to the OEM website and downloading the latest driver. Good luck!

  • My wife's Dell, Windows 7 OS, with a Broadcom 81xx wireless adapter, would have issues (with two different wireless routers) reconnecting with the wireless network at home after waking from 'sleep'.  I verified the wireless adapter had the most recent drivers and it's properties were set to NOT conserve power.  Even after the aforementioned, the laptop would not connect after 'sleeping'.  But her problem was an issue with 'hibernation', not 'sleep'.  Three days ago I changed the "what to do when closing the lid" from 'hibernate' to 'sleep'.  Three days later, and multiple times going into and out of 'sleep' (not hibernation), the latpop connects without issue.  I hope this simple fix helps every else who has exhausted the other possible solutions like we did.

  • This problem on a Dell Precision m4500 was (partially) solved for me by turning the wireless off and on again at the physical switch i believe most laptops have on the side of the case.

  • Hi, I have had similar problems, and I have tried all the suggestions I have found, but finally think i have sorted it out....

    I have a HP pavillion dv6 with a Ralink rt 3090 card

    I completely uninstalled my wireless card downloaded the driver direct from the HP website  and reinstalled - problem solved, im not sure why but it is!

    (make sure you download the driver before you uninstall the card!!)

    Hope this can help some of you

    The problem seems to be with Win 7's Homegroup.

  • WORK AROUND:

    I too have this problem, and only have a workaround, but at least you do not have to restart windoze.

    I created a shortcut on my desktop for the network adapter. Start -> control panel -> network sharing center(or what ever yours is titled), ->'change adapter settings. Now you will see a listing of your adapters, and can drag the appropriate one to your desktop or quick launch. I did this to save all the steps to go find it.

    When i wake from sleep, i right click this short cut, and disable the adapter. I wait about a second and then enable the adapter. The network will then reconnect.

  • My ASUS X5DIJ would loose wireless on sleep and after restart, i would have to manually turn it on every time ... I changed power saving settings, registry etc nothing worked,  and then one day i noticed a rattle in my laptop , a screw had come loose i new this sound because it had happened before ( the sweat shop workers never propperly tightened my screws.. dont blame them!) Anyway so i opened the laptop found the screw and found a screw hole with an arrow on it ( i think where the network card connects to the motherboard) so i replaced the screw and re tightened all the screws i could see , and now no problems with wireless card, this must have been the problem a loose screw...

  • Hi everyone,

    I have Hp dv6 series... I faced the same problem...Error 701 at start up and network adapter disconnecting when idle,in sleep mode and hibernation!!! I updated bios, updated network drivers and was thinking to restore windows until I found a solution which worked for me. If you have hp then go to Recovery Manager in start menu>under I need help immediately, go to hardware driver re installation and you are good to go....Solved my problem at least. Its going great for a couple of hours. Hope it doesnt get bad again. GOOD LUCK!
