I can't be of much help, I abondoned WEP a long time ago because it is insecure (paradoxically so) and the key entering was a big problem. I usually copied it in a document and sent it to the computers.
I had a laptop that would show it being disconnected under WEP, but it was connected, weird stuff happens.
