Intermitten ethernet drop outs on Linux

[Arika]

I recently distro hopped from pop OS on my laptop to manjaro, because i kept having stupid little issues popping up that i just no longer wanted to put up with.

However i'm now having maybe a even more frustration issue with my ethernet dropping out for about 5 seconds completely at random. it could be fine all day and then dropping out every few hours the next. Thinking it was maybe Manjaro/Arch, i switched to kubuntu and have the exact same issue. I know it's not my adapter or my dock since this does not happen while booted into windows (dual boot).

 

here's the information from journalctl

set-link: failure to reset link negotiation

I've tried having the Link Negotiation on the wired connection set to

• Ignored
• automatic
• manual

but none of them seem to matter.

I'm currently running Kubuntu 21.10

tried Manjaro 21.1.3

 

Also switched out the Ethernet cable for a different one.

the only thing i haven't really tried is going back to an LTS with an older kernal, but would really prefer not having to do this and set everything up again.

On Linux Kernel updates sometimes break stuff.

What Ethernet chipset do you have and what is the kernel version?

And what version of Pop! OS did you use?

I was using pop 21.04

Kernal is 5.13.

No idea what chipset it is as its part of my dock, any way to find this out from terminal?

chipset appears to be ASIX AX88179

Try updating to Manjaro 21.2.2,

If that doesn't fix the issue then try older versions.

 

Unfortunately i didn't find any info on the internet about the issue,

probably because that adapter isn't widely used among Linux users.
