    Today, while surfing the web my internet connection on my PC just randomly shuts off. I go check on my laptop and its normal. My WiFi says that I am connected to an Unidentified network with no internet access. So i got frustrated and checked all the forums and nothing seemed to work. So i restored my computer to factory settings and I still got this problem. Does this mean my Wifi Card is bad? Is it a virus? as you can tell i'm not too computer savvy. I can see other networks fine but i just cant connect to mine! If anyone knows any solutions please help

    Can you connect successfully by ethernet?

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.

    Identify your network, and also show ...

    Open a (black) Command Prompt window:
    Hold the Windows logo key and press r; in the Run box type cmd and click on OK.


    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.

    DO NOT uncheck IPv6. It will accomplish nothing and will affect your present or future connectivity.

    Please ignore the previous post and follow the advice from TerryNet. "Shotgun" approaches to problems are rarely successful and are not taylored to the problem at hand.

    Do you have anything in the house that could interfere? Wireless cameras, phone equipment, other wireless devices?

    Is something using a lot of CPU in your Task Manager?

    I am using my cellphone that is connected to the router, I also have a laptop connected. Everything but the PC seems to be fine. As I said before, i restored my computer to factory settings as a final solution. Even then it still wont connect. That is what led me to believe that there is something wrong with my wireless card. I have not changed the settings before today

    All those network signals are too weak for a reliable connection. Make sure you have the latest wireless driver from the laptop manufacturer's web site (because it may be only a driver issue).
