I have a wireless network setup at my apt. There are 4 other users. Everything worked fine till last night. I am still connected router and have a fairly strong signal. We have a cable modem, wireless router, and a signal expanded. When I open up explorer and try to go to any webpage it says can't find server. I tried reconnecting, restarting, and still nothing. Any ideas?
