 Yet another "me too". I'm compiling "Openwrt Reboots" latest trunk to see
 if NBD's fix works. I'll send ath9k debug logs and keep you posted.

 After 21 hours and a lot of traffic (streaming by WLAN 2.4G movies in Full
 HD), the router crash again :(

 Im running now 12 hours without any problem with the r48239 (
 
http://git.openwrt.org/openwrt.git?p=openwrt.git;a=commit;h=8ec3f0b98716a01ef8a174f90851e8ce6ea6df9c
 ). Choose this release without a specific reason, just to try some release
 with kernel 4.3.3.

 If I update to the last trunk 2.4G stop working.

 If you want to I make a test with some specific release, please comment.

Comment (by gazambuja):

 Some more info and test:

 - CC 15.05.01 work fine.
 - This revision (with kernel 4.3) work fine:
 
http://git.openwrt.org/openwrt.git?p=openwrt.git;a=commit;h=8ec3f0b98716a01ef8a174f90851e8ce6ea6df9c

 In all testes, when fail, is when more than 3 devices use 2.4G or when one
 of this put a lot of traffic, for example, streaming some video to other
 device.

 oka, this is great! some light to this issue.

 One more test: connect 3 iPhones to wlan1 (without encryptation: open
 system) and the interface crash. After few seconds we have no more access
 to router using radio1.

Comment (by anonymous):

 these two messages
 {{{
 Wed Apr  6 01:25:31 2016 daemon.debug hostapd: wlan1: STA
 0c:41:3e:4a:f5:44 IEEE 802.11: hostapd_public_action - action=0

 or invalid frame

 }}}

 indicate public action frame which is used in wifi direct is causing this.

 if you google this few results show up from sophos community where they
 had the same issue. the interesting one:
 https://community.sophos.com/products/unified-threat-
 management/f/60/t/56369

 on page 5 there is a mention of their fw release 9.104 that fixed the
 issue.

 on this link fw release summary can be found:
 https://blogs.sophos.com/2013/08/08/utm-up2date-9-104-released-2/

 this could be the bug that's affecting our devices: 25766 RED 50
 connection is permanently dropped after HA takeover

 HA takeover probably stands for handle_action takeover.

Comment (by gazambuja):

 I try connect 4 devices to 5G, and: download torrents, share screen, and
 copy some big file over ssh.
 Without any problem, the wlan0 never fail. All work just fine.

 After this try, I change all devices to 2G... and just 2 minutes after,
 wlan1 stop working.

Comment (by gazambuja):

 I'm doing some more testing, but the 2.4GHz issue appear to be some issue
 when this interface have some traffic adove some line...

 For example:
 - One phone using youtube: no problem.
 - Two phones using youtube: no problem.
 - One phone sharing screen to the TV (android -> chromecast): wlan1 crash.

 I put some traffic over 2.4GHz (copy some big file and start to download
 torrents...) and some minutes after that, interface stop working, here you
 have the logread from the last seconds of wlan1 working:

Comment (by anonymous):

 i've experienced similar on 5G and figured it happens on newer
 distributions, for example wifi would freeze on ubuntu 15.04 but on 10.04
 with some v3 kernel and wireless backports 3.18 works without
 interruptions. maybe you should try that first?

Comment (by gazambuja@…):

 I start a bounty (USD 250) for this bug, this way we can get full Openwrt
 working over Xiaomi Mini: ​https://www.bountysource.com/issues/32309542
 -no-connection-on-wlan-in-2-4g
 If any can help (with more money or solving this issue) I would
 appreciate.
