The USR is WiFi certified, so I don't think that is the problem.

I can't check for the Orinocco card without opening the laptop up (which I'm not going to do for warranty purposes), but I haven't read anything in any document about it being WiFi compatible.

I hope it is though, because that would mean there's another reason why I'm not able to keep a WEP key-enabled connection going. OTOH, I have absolutely no idea what it could be then.
