OK. Better leave it out from now on, it's not a good idea to use random
workarounds for old issues on a different wifi chip :)

I think you should start by using more recent drivers, Linux 3.2 is a
bit old. Pick up a recent compat-drivers release -

Also, how exactly are you measuring performance?

Once you have the new release installed and are running some performance
tests, it would be helpful to post the contents of
/sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/stations/*/rc_stats

It'll show how well the individual 802.11n rates are working.
