    I have a desktop and 2 laptops connected to a wireless router on my home network. I used to be able to get internet access on all 3 computers, but suddenly one day I can't get on the internet on my desktop. The 2 laptops have no problem getting on. I am at a total loss as to what to do. I am really good with computers, but networking is all new to me. Any help would be greatly appreciated.

    Pulling my hair out!!! :confused:

    Thanks,
    Bob

    Open Internet Explorer. Click Tools > Internet Options > Connections > Lan settings > Proxy server > Advanced > delete proxy server settings > click OK > uncheck all boxes > click OK.

    In Firefox, click Tools > Options... > General > Advanced > Network > Settings > delete proxy settings > select No proxy > click OK.

    Well, I did what you suggested above. It didn't show that a proxy server was being used. Everything was blank. Any other suggestions. I am at home now and can supply you with additional info if needed.

    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.

    you can double click the local area connection icon next to the time (if it's visible) and then click the properties button > select Internet Protocol (TCP/IP) and click properties

    then set "Obtain an IP address automatically" and "Obtain DNS server address automatically"
    click ok and ok

    wait 1-2 mins and do another ip config and post it back here

    if you don't have that icon
    click start > right click on Network Places > click properties
    right click on "Local Area Connection 3" click properties > select Internet Protocol (TCP/IP) and click properties

    then set "Obtain an IP address automatically" and "Obtain DNS server address automatically"
    click ok > click ok

    wait 1-2 mins and do another ip config and post it back here

    Another ipconfig /all please. If it is back to the previous static IP configuration you may have an anti-spyware application that is "restoring" it when you shut the system down.
