Hi. My airport doesn't seem to be working. It's completely connected--I even ran through the diagnostics and it said nothing can be done for it--but it won't pull up a Safari page, let me log into AIM, or check my Mail. It works fine when I plug an ethernet into it, and I've tried restarting my computer multiple times, and I reset the DHCP, too, and nothing... Anybody know how to fix this?
