Hi, I was to fast when saying in September that I do not have any issue with this NIC: under havy SCP traffic (let's say some GByte) the connection locks and I have to run 'netif restart' to wake it up; it seems that powersave is off: # ifconfig wlan0 list sta ADDR AID CHAN RATE RSSI IDLE TXSEQ RXSEQ CAPS FLAG 00:13:f7:0d:08:48 2 7 54M 35.5 0 1219 64016 EPS AE RSN the kernel is 11-CURRENT (r269739) and I have IEEE80211_DEBUG enabled: # fgrep IEEE80211_DEBUG sys/i386/conf/GENERIC options IEEE80211_DEBUG # enable debug msgs # wlandebug -i wlan0 +state +power net.wlan.0.debug: 0x0 => 0xc0000<state,power> In /var/log/messages I see now lines like this: # fgrep kernel /var/log/messages Oct 26 08:22:44 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode on Oct 26 08:22:46 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode off Oct 26 08:27:46 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode on Oct 26 08:27:48 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode off Oct 26 08:32:48 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode on Oct 26 08:32:50 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode off every 5 minutes...
