Hi, I use a 4306 (core rev 5) with compat-wireless-2009-05-08 as wireless driver and 4.150.10.5 firmware. My station is an airo card in wpa-psk mode (802.11b). After resolving my beacon problem [1], when I download at max speed my station disconnect from AP because "LostSync-MaxRetry". After looking in my station statistic it seems the retry (RetryLong) are due to noack received from the AP. Who is responsible to generate ack ? The firmware or the mac80211 stack ? Any idea to investigate this ?
