You can use the full trunk backport by using the package from this repository: http://nbd.name/gitweb.cgi?p=aa-mac80211.git;a=summary I'd recommend comparing that with the older version. In addition to the different throughput values, please also provide rate control statistics from /sys/kernel/debug/ieee80211/phy0/netdev:wlan0/stations/*/rc_stats
