    Hi everyone, I am working on a friends HP laptop that suddenly lost it's ability to see any networks at all. When I try to enable it in network and sharing it stays disabled. Just to be sure it wasn't hardware related I ran a ubuntu live cd and was able to connect with no problems. I tried updating the drivers,installing and reinstalling the network card with no luck. I also tried letting windows repair it but it says there may be driver problems. Any ideas?

    Thanks,
    Larry

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Trying to use an integrated wireless adapter or external? You have installed, or tried to install, the latest driver from HP's web site (if integrated) or the external card manufacturer's site?

    What is listed in Device Manager under Network Adapters? What, if any, warnings or errors are anywhere in Device Manager?

    If there is any evidence of an ethernet adapter or controller can it be enabled?

    I just tried to use a wireless usb adapter that I know works but that cannot be enabled either. This systems has webroot security on it could this be causing a problem? I turned it off but it didn't help. I will uninstall it if necessary. I won't work without a Internet connection anyway. I have installed the latest drivers I found but not from HP. I'll do that. No warnings or errors but it does state that there may be a driver problem.

    Seems like it's a hardware (motherboard) or Webroot problem. So, uninstall Webroot (and it they have a Removal Tool to clean up junk left behind run that also) and try to install the drivers from HP's site--I'd start with the chipset drivers if supplied and then the networking. Those actions should take care of any software issues.

    I had no problem connecting with the ubuntu live CD so the hardware should be ok,No? I just installed the drivers from HP and still no connection. Three kids play on this pc, who knows what happened.

    I had forgotten the Ubuntu results.

    You got rid of Webroot, right? Try the following repairs. After that I'd be losing patience and reinstall (or "Recover to factory defaults") Windows.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Vista or 7.

    Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.

    Yes I got rid of Webroot
    TCP/IP repair options didn't work (reset ipv6 said there was nothing to reset)

    wireless config already set to automatic

    Recover to factory defaults?
    Will I loose data and programs that I installed?

    My patience is gone and so is my hair..
    Maybe I'll let him take it to geek squad.

    I will get that screenshot from Xirrus Wi-Fi Inspector when I get home

    Forget the Xirrus screen shot. That was just in case I was misunderstanding whether the wireless adapter was working at all.

    Windows updates will need to be reapplied. Programs will need to be installed. Data will need to be restored from a backup source.
