My system, fed by a DSL modem, consists of 1 iMac, Apple TV2, iPad, and iPhones. The Mac and ATV2 are hardwired, and the rest wireless. For the past six months this worked fine using a D-Link wireless router. Recently, I lost internet. Since I can connect directly to the modem with the Mac and everything is fine, I assumed it was the router. Last night I connected my new Apple Extreme router; same problem, no internet through the router... The only thing it tells me is "No IP address", but stops short of telling me how to gain one... Shouldn't this setup by it's self?
