reconnecting issues with Dell Axim x3i

Has anyone else had problems with reconnecting a Dell
Axim x3i through a Microsoft wireless router?

Sometimes I can connect fine through the Axim but often
after a power-off or wireless
disable/enable (or even just a period of inactivity) a
couple of soft-resets are the only way to reconnect. The
WLAN seems to get stuck in a state of perpetual
rescanning where it goes right by the correct channel and
doesn't connect. The site survey screen shows my network
with 100% signal but can't access. reset a couple of
times and it works again.

Seems like there must be a setting on my router that's
wrong because I haven't seen the problem with other
wireless networks (public hotspots). I should also note
that my notebook and tivo (which are on the same network)
can reconnect without problem. I have a posting in a
pocket pc group as well, but thought someone here might
know what's wrong.

Any tips?

thanks
