    I am having trouble keeping an internet connection on (1) computer on my home network (using a Microsoft Wireless Router). I run (3) other computers on the same network with no problems. The problem computer will only keep a connection for a few minutes normally, and the problem occurs whether using the wired or wireless network adaptor. I did pick up and connect to a unsecured wireless connection of a neighbors, and everything works flawlessly. Therefore I'm fairly certain the problem lies with either the router, my ISP, or both. The problem computer worked fine for the past 3 months, and stopped working out of the blue. Any ideas or suggestions?

    Internet stops working
    Only happens on 1 PC when connected wireless or wired
    and that PC works on another wireless network without error.

    does sound like a router/ISP error

    but lets try this

    first we need to do an IPCONFIG /ALL on that machine and post back {but also can be on any machine as we are trying to find the router IP }
    then we can see if we can ping the router from the faulty PC - that will tell us if the PC can at least still see the router,
    next we will ping a domain name to see if we can get out ontothe web with a name
    then ping the number to see if its a DNS issue
    We can also try reneing the IP - but will do that later

    Sounds more like wireless interference. I don't see how it could be the ISP, since they're on the other side of the router, and other machines using the router don't exhibit the problem.

    I think i have found another issue. My NetBios on the problem machine keeps disabling itself. I found a process to reset:

    TCP/IP stack repair options for use with Windows XP with SP2.

    For these commands, Start, Run, CMD to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset [log_file_name]

    Note: the log_file_name needs to be specified, e.g. netsh int ip reset reset.log

    I do this and it works for awhile before disabling itself again.

    You have either a corrupt installation or spyware/malware. I'd suggest you post a HijackThis log and let the security folks take a look.
