HELP! Its been a long 3 weeks of continual re-boots and Ethernet wires... For some reason, my MBP (version 4,1)'s Airport began with refusing to reconnect with the WiFI network @ home or work without rebooting. Even if I go to the airport tab, and click turn on airport.. nothing happens... Now, (as of last night) the airport appears to identify the WiFI network, shows signal strength, but doesn't acquire a IP address or connect to the network. Is this a symptom of the WIFI card going south? how long does it take to get this repaired? I can't be without my computer longer than 2 days right now...aarrggh.
