But I'm not getting anywhere this device! While it may be apples vs oranges comparison but I have identical - "No probe response" with my TL-WN821N V3 (AR9287+AR7010) USB device using recent wireless testing (at 1e4541b73b33f9918255f36a60bdeacfae4fdb9d + htc_7010.fw 1.3 firmware). On disconnect - no attempt to recover (my net.wlan script needs to be restarted manually, maybe I jsut takes some time?) : wlan0: detected beacon loss from AP - sending probe request ieee80211 phy0: wlan0: No probe response from AP 68:7f:74:77:36:bc after 500ms, try 1/5 ieee80211 phy0: wlan0: No probe response from AP 68:7f:74:77:36:bc after 500ms, try 2/5 ieee80211 phy0: wlan0: No probe response from AP 68:7f:74:77:36:bc after 500ms, try 3/5 ieee80211 phy0: wlan0: No probe response from AP 68:7f:74:77:36:bc after 500ms, try 4/5 ieee80211 phy0: wlan0: No probe response from AP 68:7f:74:77:36:bc after 500ms, disconnecting.

Or maybe some test scenario? Also some other strange issue I observed with ath9k_htc (just for record, I'll report details them when I run on them again): - occasionally it happens I need to change USB port in order to get driver re- initialized (as it occasionally happens that device enters some locked state - 'net.wlan stop' hangs waiting for it and it needs to be removed from USB port to go further. Also after such operation sometimes this USB port appears to be useless and even rmmod && modprobe (also on mac80211 and cfg80211 just in any case) + reinserting USB stick doesn't help (error loading firmware), but plugging to a different USB port works. A bit earlier (before a set of driver and firmware patches was applied by Sujith last week) driver was "broken" to the point that it was actually causing my WiFi router Cisco LinkSys WRT120N to freeze completely (router cold reset was required in order to restore router operability) - this one is fixed so don't bother - just for reference. -- regards MM -------------- next part -------------- A non-text attachment was scrubbed...
