I have the same problem as many others here, in short the problem is the same as in this thread.
Specifically, I have the problem that I am connected via cable, but always after about 10-60 minutes the cable connection is disconnected and from that point on I work on Wi-Fi.
I have tried everything that was in the mentioned thread, also tips from here, but nothing really help.
I am using CAT 5e cable (which I tried to replace), I have a laptop Dell 5511, this USB hub through which I am connected to ethernet (also tried to insert ethernet cable directly in laptop, but the problem still occured).
I've tried also this: "We replace the r8169 driver by installing dkms and r8168-dkms and rebooting. We then observe to see if the problem is fixed." - did not help.

When ethernet disconnects, wlo1 interface jumps on te 1st place in the table.
I can share additional logs if needed.
Thank you in advance :)
