This was a problem in dapper for me, in edgy it is working fine. Sometimes I need to rmmod/modprobe again the ipw3945 driver, in that case the old trick to disable/enable networking from the nm-applet does not work. I have now set that driver to the MODULES list in /etc/default /acpi-support, and that seems to work so far.
