Yes, I have the same adapters that you have - theWUSB54G.
It's just really perplexing because when I had the router on this machine
and the second adapter on a different XP machine, everything worked
perfectly - never once had a problem with this - so there must exist SOME
settings out there that actually work (but I never changed a thing on their
PC - my only thought is that they have a newer computer, which probably came
with an updated version of XP or something, but I really do not see what the
issue can be)...... it's not a MAJOR problem, but it's not fun when you are
playing an online game or something
