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
