Hi Lorenzo, Since friday I enable dynack on an AP who serve 35 sta (on 2 MIMO 2x2 5ghz wireless cards 12&23) in outdoor (up to 8 kms) results are good. latency is good for all sta I’ll take your new patches and make one for openwrt and, recompile Thanks; Philippe Le 20 juil. 2014 à 14:31, Lorenzo Bianconi <lorenzo.bianconi83@xxxxxxxxx> a écrit : > This patchset adds support for estimation of the ack timeout (dynack) in ath9k > driver.
