    Hi everyone,

    I have been using my WRT54GS router for 3 years without issue, but recently, I added a new PC to my network (running XP) and now my laptop only has intermittent connectivity.

    The internet will basically go up and down every few minutes. I am wondering why the router (or laptop) is all of a sudden having issues. I have verified that the two machines have different IPs, and I verified that the laptop works fine when hard-wired into the router. The PC is hardwired into the router at all times.

    The info for the router is:
    Model #: WRT54GS v.2
    Serial: CGN30E...

    Any ideas?

    How may IP Addresses is the DHCP server on your routers is providing? Are you running a P2P?

    My first thought is that your router's UPnP is on, and your "new" PC is screwing with that. I have had reports where XP/Vista/7 screws with routers - especially with the DHCP setup. Turn off UPnP on the router and see if that helps. If not, also give the "new" PC a static (non-DHCP) address.

    Hi everyone,

    Just so everyone knows, I ran this setup (1 PC (XP) and 1 LAPTOP (Vista Business Ed) for around a year. The motherboard died and I took a few months to replace it.

    I only use these two machines on the network. I sometimes use my work laptop (XP), but that has not experienced any issues. I do not network the computers for any P2P networking. I probably should, but I am lazy and transfer files via USB HDD.

    The two current IP's for the machines are and

    I will try turning off the UPnP setting, but I am not sure how to give the PC a static IP.
