Hi, Some time (usually soon after connect) to AP (ar9102, client - Intel 5300) link experiences extreme delays. Pings take several seconds to return. Once link went into this state it stays there, and only disconnection/reconnection helps. I'm using Trendnet TEW632 with latest openwrt on router and latest compat-wireless on client. Problem persists for quite a long time without any real success fixing it. Or maybe those are different problems over time which just happen to manifest themselves in same way - huge link delays.
At those moments in router's logs I see lots of these messages: Nov 15 23:25:37 router kern.debug kernel: ieee80211 phy0: dropped TX filtered frame, queue_len=0 PS=0 @4302349 Nov 15 23:25:39 router kern.debug kernel: ieee80211 phy0: dropped TX filtered frame, queue_len=0 PS=0 @4302599 Nov 15 23:26:27 router kern.debug kernel: ieee80211 phy0: dropped TX filtered frame, queue_len=0 PS=0 @4307418 Nov 15 23:26:33 router kern.debug kernel: ieee80211 phy0: dropped TX filtered frame, queue_len=0 PS=0 @4307954 Brief look at the code gave me an impression that TX filtering normally occurs when client's card goes to power saving state. I have power saving option turned off on my Intel card. Are there any other cases when hardware can filter TX packets with such message? I would really appreciate any help or information. Als, if there is any interest I can provide more details about setup and describe problem in more detail. Thanks. -- Truthfully yours, Martynov Nikolay.
