The network came right up on the next boot, but all isn't good. The network performance is about 1/20th of what it normally is.
I had the same experience with the ath9k-driver since kernel 2.6.29 (ath9k-driver in kernel .28 worked perfectly and in .29 ndiswrapper helped me out). Several other people have asked questions about this (ath5k and ath9k) in the forum. Shortly after kernel .30 came out, my laptop died on me and my new laptop has another chipset, so I couldn't test kernel .31. I never tested the madwifi-drivers.
My symptoms were: very weak signal strength, breaking connections and connection speeds that made me cry for ndiswrapper... I never got around to finding the culprit, so filing a bugreport was impossible.

Vincent, Thank you for the information. At least I know I'm not going crazy... It looks like I will have to downgrade the kernel to test the older madwifi package: 08:30 alchemy:~/archlinux/config/wireless/madwifi-good> sudo pacman -U madwifi-* loading package data... checking dependencies... error: failed to prepare transaction (could not satisfy dependencies) :: madwifi: requires kernel26<2.6.31 There is a huge problem with this kernel/madwifi combination. To test the speed, I pulled a 25M test file from the server which usually takes well less than 10 seconds. Now, with the new kernel/madwifi driver: 08:25 alchemy:~/archlinux/config/wireless> rsync -uav --progress archangel:~/dsj.wav . receiving incremental file list dsj.wav 23578844 100% 201.77kB/s 0:01:54 (xfer#1, to-check=0/1) sent 30 bytes received 23581816 bytes 204171.83 bytes/sec total size is 23578844 speedup is 1.00 Now it takes OVER 114 seconds. This is a 10-20 fold increase in time. I used to regularly transfer 500-800M files across the wireless connection. Now, that is out of the question. I admit, I'm not very good at troubleshooting wireless driver issues. How would I start trying to figure out what is causing the poor wireless performance. I do have a spare laptop drive with SuSE on it that I can pop in to compare things if that would help. I just need to know what I would need to start looking at. Which files/logs may hold the clue?
