I have a d-link d-604 wired router and for 2 months it worked fine. 3 computers are connected(My PC, one in my mom's office, and a laptop). Just recently there was internet no connection. I opened the network connections (Vista) and it won't detect my router but we can detect the other computers. Also no Internet. I connected directly to the dsl and internet worked fine.But now we can't use the net at the same time. Pls help. Is my router busted or should i do something?
