I hooked up my airport express to the ethernet network at my school, and at first it worked fine. but then the I.T. guy came along and took the thing because it wasn't set up to be encrypted. i got it back and tried to set it up to be 128 whatever encryption, and now i can't get it to find the network. it just blinks amber. i reset it completely by pushing on the little button on the express, i redo everything, i set it up without encryption just like before... i can't get it to work at all with the internet! everything else seems fine, but i can't get online with it anymore! the ethernet cable and connection is fine, i hook the cable up to the port on my ibook and i get on just fine. but no luck through airport express. what happened? thanks, r.
