I recently established a home network with a cable modem and a wireless router. I have two desktop computers connected to the router with ethernet cables. My problem is that when I turn everything on using a single switch from my powerstrip, I connect to the modem but have no internet. This happens with both computers, one is Windows XP and one is Windows 7. Windows suggests to turn off the modem and turn it back on. It works and I am connected to the internet. As long as one computer is connected, another can then be turned on and has no problem. Laptops can access the internet via wireless with no problem. Is this normal? Why do I have to have a computer turned on before the modem? Is there a way to fix this?
