Will work on this when I get home from work. Thanks for the help guys.

The setup, prior to this, was the same as now with a different router. At some point our cable company installed a modem between the wall outlet and all the peripherals so they could add the HD service and telephone service. Shortly after this, the clients on my network (another PC and a WIRED X-box 360) became unable to connect to the internet.

I know I sound completely inept, but I know the cables are installed correctly (USB cable aside) so that's not the problem. I will follow the steps outlined above this afternoon and let you know how it goes.

Again, since at times I can connect to the internet from any PC in the house (just not at the same time) I can't see the problem being modem, router or NIC. Am I wrong in making that assumption? I think it has to be in my settings somewhere.

Thanks again!
