If you configure your kernel to include multiple rate control algorithms then you can use the 'ieee80211_default_rc_algo' module option for mac80211. Of course, changing that only works if you rmmod/insmod mac80211. John -- John W. Linville Someday the world will need a hero, and you linville@xxxxxxxxxxxxx might be all we have.
