I'm definitely interested in the "why."  Btw, I gave it a shot.  I'm
still getting a bit of loss (about 35% right now, but I'm a bit
further away than earlier).  I think overall the results are on par
with using a "free" channel that is two away from any nearby broadcaster.

It's possible that this isn't an interference issue, but that seems
to be the most logical explanation so far (unless someone knows of
interop issues between dlink and various laptop builtin drivers,
such as intel 3945abg).
