Unable to connect to school WEP network on Intel 4965
I am having some trouble with connecting to the Georgia Tech wireless network. I have an intel 4965 wireless chip, on a Thinkpad T61, running Arch Linux. I can connect to several unsecured networks just fine. The problem seems to be with the WEP password. In Knetworkmanager, I tried all the options, and none of them worked. I am certain I have the right password. I tried connecting using both ndiswrapper and the proper windows passwords, and with the "experimental" iwlwifi driver. Both worked fine with any other network (they were all unsecured) so I don't think it is a driver problem, but who knows.
I believe the culprit is the encryption itself. The network uses 128bit hexadecimal, and Knetworkmanager only has a Passphrase and 40/104bit HEX option. Could that be the problem, and if so, what do I need to do to connect?
