In Description, you said: "The WM6.1 device recv ps-poll's for packets every 20 seconds ..." AFAIK, STA sends ps-poll to AP; AP does not send ps-poll to STA. Why did your windows STA receive ps-poll from freebsd AP? Did you capture it by using 802.11 tap? And which freebsd driver were you using? Your problem looks like: - Either freebsd AP did not properly configure TIM in beacons, which could be easily found out by using 802.11 tap. But I highly suspect if you were using ath(4), TIM would be misconfigured. - Or your windows STA didn't process TIM according to 802.11 standard. Best Regards, sephe -- Live Free or Die
