Freebsd 7 release wireless problem

[Jie Ouyang]

Hi list:

I have Freebsd 7 Release installed on my laptop and the dhcp client works
unstably with WIRELESS connection. It does not get IP unless the DHCP server
on the router is restarted. I am kind of sure this is the problem with
freebsd as I installed ubuntu and windows xp on the same laptop with no
problem with dhcp. Any hints to work around this issue? Here is some
information

System:
Dell Inspiron 600m
PM 1.5 G. 512m
Intel Pro 2100 802.11b.
FreeBSD 7 release generic kernel .


I have
if_ipw_load ="YES"
legal.intel_ipw.license_ack=1
in /boot/loader.conf

Run "ifconfig ipw0 up scan " gives
