Hi wwp!

For your sake I hope others better than this beaten up "mature" man.
This is a hobby for me.

What I have found is that if you Google "kernel: ipw2200: Firmware
error detected. Restarting" you get a lot of bug hits. One tutorial
I ran into doing some "additional parameter Googlling" (added "fedora"
to the search) is:

http://www.ces.clemson.edu/linux/fc2-ipw2200.shtml

Which seems to bring up most issues I hit and some ways to find and
manage them. It is a bit dated however.

Good Hunting!

Tod
