Hello, I am pretty new to the N under linux thing, so any guidance would be great.
I have the equipment in the subject, and under the stock 2.6.27-r6 gentoo
kernel I get a transfer speed of 2MB/s as reported by rsync -ahP with a 100Mb
file (across nfs). I am using WPA2 tkip.
I get the same results with the compat-wireless-2.6 tarball.
With the latest wireless-testing git, plus wireless-compat (both from
yesterday), I get around 100Kb/s transfer! Not really heading in the right
direction.
Below is the dmesg on the ath9k load with debug enabled (with the latest
wireless-testing and compat). I have the AP set to N-Only on both 5Ghz and
2.6Ghz channels. Any tips on getting this up to speed?
