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?
Thanks.
