Hello, Adrian. You wrote 26 =E0=EF=F0=E5=EB=FF 2013 =E3., 4:11:44: AC> Ok. Next time it happens, force a stuck beacon: AC> sysctl dev.ath.X.forcebstuck=3D1 AC> That will cause the right kind of reset in order to log the frames in AC> the TX queue. AC> Make sure you have the right debug mask though! Without reboot (iface dow/up) it showed very low speed (~30Mbit UDP) with clear environment (RSSI 28, RATE 270M according to list sta). After router reboot it is 140-160Mbit/s UDP (2x2 MIMO, HT40 channel), but with drops to 20-50M for 1-2 seconds. But I cannot repeat previous hang in this "clean" conditions :) It looks like I need wait night :) --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
