I did not try that; but after I originally reported the
problem, Kevin Oberman suggested that it could be a routing
issue, so I flushed my routing table, and now have been
happily getting DHCP leases over wi0 whenever I need
them. When I remember to do this, I have no problems going
back and forth between Ethernet and wireless.
