Wifi unreliable

ARM Technical Assistance

Hello, since recent update (6.0.13-1-MANJARO-ARM-AML) I have been noticing that my wifi network is almost unusable, it seems to de-associate or similar, I’m not sure but i looks like it happen as soon as there’s some load.

What I was able to get from dmesg was:

How could I debug it further? if I disconnect and reconnect it works again for a while and then same issue.

This sounds like the same as @JFL and one other user was experiencing.

@spikerguy Maybe it’s a firmware issue or a brcm driver update in the kernel?

It’s too early but so far it seems that sudo iw dev wlan0 set power_save off is helping…

There is a slight difference. In my case WIFI is only available for a minute or two, load or NO load. After that WIFI and Network is no logner available and if you close Chromium and try to relaunch Chromium or other applications, most of the time it will NOT launch anymore. The system basically become unstable – this is with 6.1.y. It might be mainline upstream 6.1.y issue as I had also tried 2 other kernels 6.1.y (build by ophub/unifreq and Armbian 6.1.0-meson64) and both also had the same issue.

On linux-6.0.y the last i tried the earlier version, I did not face any WIFI issue.
