Oh, hurrah.  This does seem to reliably reproduce the problem
(quickly) on my machine as well.  I have seen these errors on my
DWL-650 before, but when I went to investigate, I could never
reproduce the problems.

Oddly I seem to get more errors pining the AP this way than if I ping
a machine on the wired network on the other side of the AP.

That would probably be when dhcp buts the interface into promiscuous
