@akorolyov I have rolled back to Chaos Calmer in the meantime, it works smoothly. Stable versions are stable ;)

[akorolyov]

@yonyonson Model: Linksys WRT3200ACM current firmware: OpenWrt Chaos Calmer 15.05.1 r49389 / LuCI for-15.05 branch (git-16.206.66468-6f5c466)

It downs a few times per day and only wifi.

Hmm, I am runinng on r48532, hardware is WRT1900ACS.

I can see that I have older drivers

Here are some relevant packages installed:

PS: I can see that current version of kmod-mwlwifi that is available here ( https://downloads.openwrt.org/chaos_calmer/15.05.1/mvebu/generic/packages/base/ ) is 3.18.23+10.3.0.16-20160105-1

WRT3200ACM has problem. I close this issue. If you still encounter this kind of problem on devices other than WRT3200ACM, please let me know.

[akorolyov]

@yuhhaurlin does it mean that WRT3200ACM has hardware issues instead of software issue?

[kevle]

@yuhhaurlin The Problem is also still present on the 1200AC and 1900ACS. I can share an abundance of log files as we have 14 devices frequently crashing. Is there anything we can do to help debugging it? We will try the old kernel that was almost stable until then.

[Chadster766]

@kevle I haven't see this issue with the WRT1200AC or WRT1900ACS with the latest mwlwifi driver.

Please run the below command so we can see which driver version you have in use:

cat /sys/kernel/debug/ieee80211/phy0/mwlwifi/info

[yuhhaurlin]

@akorolyou The problem of WRT3200ACM is related to firmware of chip.

[kevle]

@Chadster766 Currently I have reverted to the stable version of OpenWRT which seems to be more ...stable.

[Chadster766]

I've never run that driver version.

I recommend using drivers versions 10.3.0.17-20160531-1 or 10.3.2.0-20170110.

[jklap]

10.3.0.17 shows this problem for me.

[Chadster766]

@jklap is the driver version you are using between 10.3.0.17 and 10.3.0.17-20160531-1?

[woody77]

I'm reproducing this on a WRT1900AC (v1), with 10.3.2.0-20170110

(two laptops on the same radio playing minecraft over wifi and it crashes regularly)

Does it have a new mwlwifi only or some debug turned on? Thanks

[yuhhaurlin]

It is the last version of driver. If you can reproduce this problem and let me know the way. I can try to reproduce the problem here and check it.
