Wait . . . the new router does not work either ~ should I try the reset button on that one also?
It won’t hurt the router but reset just one thing at a time otherwise it’s hard to diagnose what’s happening. Limewire CAN create problems and has done so on my network. Could you provide a little more info on the router make and model number. As one poster mentioned earlier if you have only a switch and not a router with a built in switch THAT may be your problem.
