Just got my brand new Powerbook. Figured I'd go to campus, try out this wireless connection and do my homework amongst the peoples of my university instead of my room (aka eternal prision). Problem is I can't even detect a connection. My friend's PC can do it, but Apple's internet connection program can't pick up anything. It can pick up my home wireless connection supplied by my Extreme Basestation. But nothing else. Any clues as to what could be wrong? Are there any programs that can detect signals better than Apple's?
