    Hello, I have problem. I have several computers connected through a Linksys WRT54G router and they all connect fine. However, I have one computer that can't connect through the router. It connects fine when I plug it in directly to the modem but that's the only way that I'm able to get it online. Are there any settings I should change to get it to connect through the router? I'm desperate. Please help me out!

    On the problem computer, with it connected to the router, do this:

    For 98 or ME, Start, Run, COMMAND to open a DOS window:
    --- or ---
    For 2K or XP, Start, Run, CMD to open a DOS window:

    Type the following command:


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

    you may just have to do a release and renew in the cmd window johnwill suggested.
    Type ipconfig /release
    wait for results
    type ipconfig /renew

    you may also want to check the properties of your network card , tcp ip settings and make sure they are set to obtain an ip address automatically.

    Does that one computer have any type of "connection manager" software installed that was provided by your ISP? You may have to uninstall it to restore normal operation of your network interface card. I had that problem on my father-in-law's PC running some SBC/Ameritech software but the uninstaller did not work right. It turned into a real nightmare.
