Ethernet connection missing with r8169

[HL77]

Sorry, forgot to reply for following ideas:

sudo ip link set enp39s0 up
This didn’t make any difference (didn’t work).

When booting to live .iso everything works as a charm.

sudo rmmod r8169
Doesn’t give any response, but when executed for second time, the reply is that module r8169 is not loaded

When executing
sudo dmesg -w
sudo rmmod r8169
there is nothing

After
sudo modprobe r8169

… and internet connection is back.

Also, I’ve installed system update this morning and it didn’t make any difference.

@HL77

sudo ip link set enp39s0 up
This didn’t make any difference (didn’t work).

Hmm, and there wasn’t any error message printed out? I’m asking because by documentation the command is silent on success but should print an error when failing.

@HL77

sudo rmmod r8169
Doesn’t give any response,

This means the module was loaded. I just don’t understand how unloading and loading it again should make any difference.

Ja!

This reminds me of this thread:

Netzwerk Interface gelöscht, wie wieder herstellen?

Ich habe nur den Eintrag in den Plasma Settings gelöscht. Aber der Grund dafür war, dass der Adapter schon vorher nicht lief und ich im Arch-Forum den Hinweis gefunden hatte, den mal in den Plasma-Settings zu löschen. Lt. dem Hinweis sollte er dann nach dem Neustart wieder neu angelegt werden. Aber scheinbar habe ich noch ein anderes Problem?

I don’t think trying r8168 is the way to go, but… I see that there is kernel module software available. Have you tried installing linux70-r8168?

Manjaro HardWare Detection command suggested in previous post would install linux70-r8168 and linux70-headers

Pacman log would show if such packages were installed or removed:

grep 'linux70-' /var/log/pacman.log

I have tried several times to install with mhwd the r8168, but it didn’t make the internet appear.
