Comment 64 for bug 200509

I had the same issue on Jaunty with every kernel I tried (2.6.28,2.6.29,2.6.30rc3). I found a suggestion given at:

My wireless is running smoothly since then. I need to do more testing, but so far so good. To summarize, you need to do:

echo 5 > /sys/bus/pci/drivers/iwlagn/0000\:0c\:00.0/power_level

replacing 0000\:0c\:00.0 with your entry. Please see the above link for the details.
