I have a iMac, MacBook and PowerBook G4. They were always able to connect wirelessly until today using my Airport Extreme. I reset the router. I shut off my Comcast router and then turned on the AE. It gets connected to the wireless connection and gives me an IP address of 10.0.1.x. Signal strength is excellent but I can't get any web pages to come up. I connect an Ethernet cable from the Comcast router to my iMac and I get online w/o any problems. The same result happens on the MacBook and PB G4. When I put in the router address when connected wirelessly I cannot access the router. I've never setup a Airport Extreme before. Any hints on this is done would also be appreciated. What can I do so I get my wireless connection working properly again?
