i'm sure that everyone is very tired of hearing about this prob - lord knows i've been reading about it for months with no end in sight. i own a macbook core duo, and somewhere between the 10.4.10 update and the purchase of my blackberry i slowly started losing the ability to connect to any unsecure / open wireless networks that i previously had no problems with. i can, however, connect at the cafe i'm sitting in right now. this is really frustrating and is becoming increasingly so. my flatmate can connect to a variety of our neighbors routers, and where i used to be able to i now cannot. please help!
