Random disconnect with Ethernet cable

General Help
1

Hi,

I'm running the last core version of Zorin and i'm experiencing troubles with random disconnections with ethernet.

The PC is setted with a dual boot, i have no trouble at all on Windows. It's not hardware, not a cable issue, not a router issue. It's only on Zorin.

When i'm using the computer, the ethernet connection is lost for 10 to 120 seconds randomly, multiples times per hour. It's really annoying when being in online meetings or uploading huge files.

Whatever if i unplug/replug the cable, i just have to wait for 10 to 120 seconds and the connection restore.

It's random, and really annoying. All external causes have been eliminated.

Help appreciated, it's ruining my work lately... And ha, i formatted PC last week for a fresh new Zorin install to try solve this, but unfortunately... The formatting didn't helped.

Cheers.

Have you disabled Fast Startup in Windows?
Run these commands and post the output

sudo dmesg --level=err,warn

journalctl -p err --since "2 days ago"

I'll check but i think my windows have fast startup disabled for years.

Your command is not working, it returns error :
dmesg: bad usage

4

There are two different commands, run them separately.

5

i'll try the two commands later, but i'm on windows right now and checked : the fast startup is off as expected.

Did you enable the system option Power Save or changed the Ethernet settings?

@Luca_Pavan:

  • Ethernet Settings are basic, DHCP, no proxy, local router DNS
  • Power setting : "Balanced"

Up ? I'm really annoyed by this issue and can't figure out why..
