I have an ipw2200 too and the disconnections disappeared since I use
WPA2. Before I had a router with WEP only. The new router runs with the
Linux-based open-source firmware Tomato. I don't know if WPA2 or the
firmware fixed it. Testing WPA2 is not a big effort, but the reporter of
this bug wrote that he is affected using WPA2.
It's not completely solved for me, but disconnections are very rare now.
My investigations of this bug let me think that it's a kind of buffer
overflow in the firmware or driver for ipw2200 adapters (or similar).
The more data I sent or received, the more often it got disconnected
(try "cp /mnt/nfs-server/bigfile /dev/null"!). Switching speed did not
help. I think a high relation of "currently used bandwidth" against
"theoretical maximum" is what triggers this bug.
