Hi! this is because we don't have A-MPDU RX aging on by default. So, if there are holes in the sequence number space, FreeBSD's reordering logic doesn't flush frames up until it's received /all/ the traffic. I've just enabled it by default in -HEAD now. That should fix it. Otacilio, you should be able to fix it locally by adding options IEEE80211_AMPDU_AGE to your kernel config file and recompiling. Sorry! -adrian
