OK, heres the story. I have called my ISP, they directed me to Apple, but none of my computers have the APP. My iBook can see the airpirt network and i can transfer files between computers, but it won't go on the internet. When I plug the ethernet directley from the modem to my iBook, it can go onlin so its obviously trhe AirPort Extreme that is the issue. ANyone know what to do?
