MacBook Air only connects to my wifi at home - not public wifi
I'm using a MacBook Air 3,2 (processor speed 1.86GHz, memory 2G with OS X 10.6.8) and it will connect to my wifi at home but won't connect anywhere else. I've tried at multiple Starbucks, libraries and coffee shops. My phone will connect to the wifi there but not my Mac.
Any idea what the problem could be or how I could troubleshoot?
MacBook Air, Mac OS X (10.6.8)
