I used my aiport express at home to play music and it worked great. But now I'm at school and when I plug it in with the ethernet cable in, the light is green but when I connect to it I can't view the internet at all. Using the Express Assistant I can configure the password for the network and change its name, but at the end of it, it says it cannot find a base station... yet just seconds earlier a notification will come up saying the wireless network i just configured is available... when I connect to it I can't view the interenet though... I'm totally lost... I've tried the reset button and all that, does anyone have any suggestions?
