hello, I can't get my airport card to work any longer on my first generation MacBook Pro. I am not sure if it is a hardware or a software issue however... ...the airport has a check next to my wireless network, however an exclamation mark in the menu bar ontop of the airport reception icon. It reads "Alert: No internet Connection" in the airport menu... ...I tried logging into a new account to see if it was a user setting, but same thing. Do i need a new airport card? Where do I get one? thanks, r.
