I am trying to connect to a wireless network with WEP protection. When I enter the wep code (28 keys), I always get an invalid password message. There is a good strong signal. I am using this network via ground wire to write this thread. I use the same password for 4 other computers (all PC's) on this network, all wireless. I have been on the phone with Apple Care and they can't seem to help. I know the Airport is working because I can connect wirelessly to other networks. The routher is a Netopia Cayman 3374W Any thoughts?
