I have a 2-week old 12' ibook. It's been working on the wireless networks at home and at school without a problem, but today it won't connect at school. I haven't changed any settings, and other people around me are connecting without a problem.. I can only get the little picture of the computer in the airport part, which is computer to computer I think.. which won't help me get on the internet, right? The weird thing is that this computer to computer network is called the same thing as my regular school network. I tried reconfiguring everything, didn't help. Any suggestions?
