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?
