Reason for the ? is because I'm not sure if this is really a problem or not. Whenever I'm at school there are certain places (inside classrooms mostly) I get either of these scenarios: 1. I get no signal whatsoever and my AirPort doesn't even detect the network 2. My AirPort will be able to detect the school's network but when I try to connect it says "<Network name> cannot be found" 3. If I do connect I'll get such terrible 1 bar signal that it's impossible for me to do anything. Some key facts that you must know: -EVERYONE else is able to connect! i.e. A student to my left, with the newer MacBook, will have a strong connectivity, and to my right will be student to my right with a Dell and has full strength connectivity. What is the deal here? -I have a wireless router that I use at home and it connects to it no problems at all for the entire time I've had it. Full strength connectivity. I have the last generation of the 12" PB 1.5.
