I'm running Ubuntu 9.10 and after a recent reboot, I'm now unable to authenticate to wireless networks using WEP encryption.

I can connect fine to open networks (no idea about WPA).

When trying to connect via WEP, I'm continually prompted for the network key, which I know I have entered correctly (and should have been/is saved in my keyring anyway).

Everything had been working fine until the reboot. No updates had been installed or configuration changes made.

Hardware-wise, everything looks fine (http://pastebin.org/113777), and the fact that connecting to an open network works just fine leads me to think this is a software issue.

I just don't know where to begin fixing it.

Any insights would be greatly appreciated.
