Hi all,

I started having the same problem after upgrading to Jaunty. When the card disconnects the only way to reconnect is to either reboot or do
rmmod ipw2200 && modprobe ipw2200
however the rmmod command completely hangs the laptop in about 20% of the cases.

I will try Steven's suggestion.

I sometimes get "Firmware error detected" in isolation, but it doesn't cause any disconnect that I'm aware of. When I'm disconnected I get the below in /var/log/messages:
