Clients unable to connect to WiFi 2,4GHz and/or 5GHz

Description

Hi

I'm having issues with connecting to my router with WiFi.
After some days working fine suddenly clients become unable to connect.
Does not matter which client OS is running (Win,Android,iOS,OSX,Linux).
This affects both, 2,4GHz and 5GHz bands. Sometimes both, sometimes just one.

My hardware/software is

Hostname	OpenWrt
Model	Linksys WRT1900ACv2
Firmware Version	OpenWrt Chaos Calmer 15.05 / LuCI (git-15.248.30277-3836b45)
Kernel Version	3.18.20

Running mwlwifi driver.

While clients are unable to connect I'll get this logentries:

Restarting hostapd doesn't help, simple /etc/init.d/network restart doesn't help too...
After reboot it works for a while as mentioned before.

The temporary solution found so far is a reboot.

Please reply if I can provide any other data/info needed.

Please test if openwrt trunk is affected by the same issue

comment:2 Changed 2 years ago by jnko

Ok, I will test it. Will take some time since I do not know how to force this issue.
Will reply in any case.

Ok, I'm back with some news.

This morning my Nexus5 was able to connect to 5GHz network.

Later on I tried to connect a Nexus 10 to the same 5GHz Network which failed:

Interestingly the Nexus5 was still connected and the connection worked.
After disconnecting the Nexus5 the reconnection failed too:

Well I can leave the router "as it is" in fail state for a while. Is there anything I can provide for further information?
(Logs, dmesg ect...)

Another update. After peeking around a little bit I found that the connection with my Nexus10 *sometimes* work - but unstable.

The 5GHz band never gets a connection, but on 2.4GHz connection succeeded sometimes.However it is very unstable though.

Here is the log:

I can reproduce this bug also on my Linksys WRT1900ACS, which uses mwlwifi as well. Same effect, same error messages.

DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='Bleeding Edge'
DISTRIB_REVISION='r47811'
DISTRIB_CODENAME='designated_driver'
DISTRIB_TARGET='mvebu/generic'
DISTRIB_DESCRIPTION='OpenWrt Designated Driver r47811'

I have been losing the 5 GHZ radio here on a WRT1900ACS with the 15.05.01 release.

This only happens after all clients have disconnected from the 5 GHz AP. (Devices turned on 24/7 keep the 2.4 GHz AP active.)

The front panel LED for the 5 GHz channel turns off when this happens, and will not turn on again without a hard reboot.

If something keeps the 5 GHz channel active then devices are able to reconnect.

The deauth message I have seen is:
Thu Apr 14 19:20:00 2016 daemon.info hostapd: wlan1-1: STA 44:80:eb:11:aa:bb IEEE 802.11: disassociated
Thu Apr 14 19:20:01 2016 daemon.info hostapd: wlan1-1: STA 44:80:eb:11:aa:bb IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)

In addition, the following has been seen repetitively logged in dmesg:
[143357.290955] ieee80211 phy1: check ba result error 1
[143357.295941] ieee80211 phy1: ampdu start error code: -22

I have similar problem with Linksys WRT1200AC and OpenWrt Chaos Calmer 15.05.1. After two days after reboot the connection becomes unstable. ping -c 1000 -f 192.168.1.1 reports 79% packet loss and the router kernel log reports several times:

[204038.741512] ieee80211 phy1: check ba result error 1
[204038.746512] ieee80211 phy1: ampdu start error code: -22

Now had to add reboot every night to the router crontab...

I can't reproduce this bug anymore. It seems to me it was somehow related to "Wifi performance" bug with the mwlwifi module (https://github.com/kaloz/mwlwifi/issues/63). Since I upgraded to the lastest mwlwifi version also that "unable to connet" bug didn't occur anymore.

My wild guess: When the mwlwifi drop the connection speed to a really low value, the connecting process got so slow, that it produced a time-out.

Anybody else can verify this? Can this bug get closed?

It would be great if someone could compile the latest 10.3.0.17 version of mwlwifi as a module for 15.05.1 release.

I have upgraded the WRT1200AC router with 10.3.0.17 version of mwlwifi from mrfreeze distribution and it seems that all issues are gone. Uptime is about 9 days now, no reboots required, no lost packets from ping:
