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:
Could you try to recompile the older madwifi from svn using the latest kernel and see if that works? Also testing previous kernel with latest madwifi would be good. I'm fairly concerned about this, as I also use the madwifi drivers, and my speed is abysmal as it is... A reduction like that would put me at dial-up speeds.
Danny, I downgraded the kernel and madwifi, by downgrading the following: kernel-headers-2.6.30.5-1-x86_64.pkg.tar.gz kernel26-2.6.30.5-1-x86_64.pkg.tar.gz kernel26-firmware-2.6.30-1-x86_64.pkg.tar.gz madwifi-0.9.4.3952-5-x86_64.pkg.tar.gz madwifi-utils-0.9.4.3952-1-x86_64.pkg.tar.gz The wireless then started as usual under wlan0/ath0 and performance is back to FANTASTIC: alchemy:~> rsync -uav --progress archangel:~/dsj.wav . receiving incremental file list dsj.wav 23578844 100% 3.10MB/s 0:00:07 (xfer#1, to-check=0/1) sent 30 bytes received 23581816 bytes 3144246.13 bytes/sec total size is 23578844 speedup is 1.00 compared to the performance with the new kernel/driver: alchemy:~> 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) That's 3.10MB/s with the old kernel/madwifi combination and only 201.7kB/s with the new.

I'll change the config to wifi0/ath0 under the old kernel, confirm performance under the setup and then I'll reinstall the new kernel and try to build madwifi from svn as you have suggested. Let me know if you have any other thoughts in the mean time. Thanks. -- David C. Rankin, J.D.,P.E.
