Unable to connect to Wireless Network after Sleep/Hibernate

    I recently bought a HP laptop with Windows Vista Home Premium installed and
    inbuilt wireless. I was successfully able to establish a wireless network
    with my linksys router. The problem is whenever I hibernate my machine or use
    the sleep option, after starting up its not able to find any wireless
    networks and therefore cannot connect. If I shutdown and then restart, its
    able to detect wireless networks again and connects automatically to my
    default network. My wireless is being managed by inbuilt HP utility. It has
    to be a Windows issue as one of friends is also facing similar problems with
    a different brand laptop.
    Is that a known issue or any setting I can change to resolve.
    Any help is greatly appreciated.

    Thanks

  4. I was having hte same problem and just fixed it tonight.

    Get properties on your network connection and click on Configure...
    Then click on the Power Management tab. Uncheck "Allow this computer
    to turn of this device to save power". Click Ok.

    Now it should be fine. At least mine was fine after I did this. I
    think what happens is that Vista somehow disables the adapter (in some
    kind of behind the scenes way that you don't see) and doesn't turn it
    back on until you disable/re-enable the adapter or reboot the machine.

    I changed the power settings to not turn off the wireless adapter. I also
    disabled IPv6. Sometimes it works and sometimes it does not. Yesterday, it
    started fine after Sleep but then got disconnected after 15-20 minutes all of
    a sudden. The machine was not even idle and I was online. Then I hibernated
    it for a while and after that it didn't work. I had to reboot twice to get it
    to work.
    Once it gets disconnected, only option after that is to reboot. Nothing else
    fixes it.
    Any more ideas guys !! I cannot believe Microsoft hasn't released a patch yet.

    Romil,

    If you're getting kicked off the wireless network periodically, then you
    might be having a mismatch between your client security settings and the AP.
    Check to make sure both are the same, and let me know.

    Hi,
    I have the same problem with my newly bought HP Tablet PC. But when I open
    the "properties" box of my wireless connection and then click on
    "configure..." there is no "Power Management" tab. I looked for a similar
    option in other parts of this box but found nothing. Does anyone have any
    idea what can be my problem?
    Thanks,
    Hamid

    You can't find the tab because the Power Management is only in the wired
    properties, its not for wireless. I am still having the same problem with my
    wireless internet still disconnecting all the time, so other than that I have
    no idea what to do. I just have to keep restarting my computer to get it back
    online.

    I am having the same problem on a Toshiba Satellite. At night, i
    hibernates, and in the morning refuses to connect to the internet. I
    finds the AP and indicates local connection only. Rebooting generall
    does not help. Sometimes the repair function will allow it to get a ne
    IP address and then it will be ok. Sometimes it just quits for n
    reason. All the other machines in the house run XP and are fine
    I have updated the wireless driver, put on service pack 1, set th
    wireless router to factory settings, deinstalled Norton and still th
    problem persists

    I don't get it.
    The thing worked fine for months... I am thinking its time to get
    copy of XP and be done with all this hastle. All I use the computer fo
    is surfing the net and it basically does not work most of the time

    and update the firmware on the router. look for a newer driver for
    your wireless card.

    please post your problem in a NEW thread. you are replying to a
    thread almost a year old.
