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? ---------------------------------- 2.6.27-r6 kernel: wlan1 IEEE 802.11bgn ESSID:"xxxxx" Mode:Managed Frequency:2.462 GHz Access Point: 00:22:6B:68:B0:5C Bit
