So I've done pretty good with my mac book for the last few months! Till today I bought and set up a new Belkin "N" wireless router. It tells me it is B&G capable as well as mac. I have two windows machines working just fine. The mac book airport signal shows full strength sitting right next to the router. I move away and the bar drops by one. Anytime I open safari, and try to open a site. I get the "not connected" box. But again air port shows I am. I tried all the various settings and assistants in the O/S without any result. The net work is unsecured for the moment as well. What could be the problem?
