STA not found?

[Michael]

The problem:

I have a WinXP Home laptop that has difficulties connecting to my WLAN at
home, but only with WEP enabled and requiring shared authentication - open
system authentication is fine.  Interestingly, several other computers with
WinXP Pro (and tested with Knoppix 3.4) have no such difficulties.  If you
had any ideas of what the problem is, *please* respond - I've been at it for
a while now trying to work it out myself and am at a complete loss.
