Sometimes the network gets this. This happens after Stable Update 08-09 and Testing Update 08-13. I don’t know if it’s the kernel’s fault or some applications.

Host: FIRESTAR 
Kernel: 5.13.10-1-MANJARO x86_64 
bits: 64 
Desktop: KDE Plasma 5.22.4 
Distro: Manjaro 21.1.0 Pahvo 
Branch: Testing

When using Manjaro’s rolling release model, Kernel management becomes a thing, so please install both 5.4 and 5.10 LTS (Long Time Support) and see which one of the two troubles you least.

On both 5.4 LTS and 5.10 LTS?

:thinking:

5

No. I only use 5.13 because 5.4 and 5.10 cannot recognize my surface pro’s battery. See:

6

I understand, but have you tried???

If the network doesn’t fail on 5.10 or 5.4, it’s a regression and the solution is known, otherwise you need to try 5.14 and if it fails there too, raise a bug.

:thinking:

7

SP6 uses Marvell (mwifiex).

Also the mwifiex driver is known to have some… issues. So please do try the Surface kernel, we have a bunch of patches addressing various stability issues for that driver, which unfortunately haven’t made it upstream yet. The iwlwifi driver should be maintained fairly well as far as I can tell, so if you think this is a kernel bug you might have better luck checking in upstream.

8

Which means you’ll have to get your support from the Surface team as the Manjaro team doesn’t support custom kernels.

:sob:
