I just got my MBP 15',SR, Lep, etc. I'm at my GF's store and I cannot connect via airport. She has a Macbook w/ Tiger and has no problems. I've seemingly gone through all the utilities and such and it connects sort of System Pref.->Network->Airport..Status: Connected...But nothing. Network Diagnostics, Network Setup Assistant... nothing works. It's an open wireless connection (ie the coffee shop next door). Any help out there?
