Good afternoon, Mike
From which package have you installed the yt6801 driver? We currently have an Arch repository that have these packages, if you still have the yt6801 AUR package, you might want to switch to our repositories instead, I will link you to our tutorial to add the repositories: https://slimbook.com/en/blog/guides-2/post/add-the-slimbook-repositories-on-linux-71

In any case, if you still have the older kernel after the update (assuming your kernel was updated with the update), you can try reverting to it and check if the ethernet adapter still works

If that solves it, you have to wait for a newer kernel update to check if that issue gets fixed/have to put the interface up after booting

Regards,

Hola Samanta,

Gracias. I already have the slimbook repositories in the pacman.conf and the slimbook driver for yt6801 is not working any more.

Hello, Mike
Is this a clean installation?
If you bring up the interface with `sudo ifconfig enp2s0 up` does the ethernet work? 
As mentioned, if you have updated and if you still are able to boot in your older kernel (if the kernel has been updated), then you can see if it a kernel issue
If not, then it might just be a network configuration issue on your end

Regards,

Hola Samanta,

Gracias. What do you mean with clean installlation?

sudo ifconfig enp2s0 up 

is old.

sudo ip link set enp2s0 up 

Does not change the device status.

And I definitely donot have a network configuration issue because it was working yesterday after the upgrade. It started to fail this morning after regular updates.

Hello Mike,
I was unsure when you mentioned update if you meant an OS upgrade (from last Endeavour release to Titan) or if you meant just updating the packages
Any package update that involved networking (eg, netctl, systemd-networkd) could've changed things from the network configuration

Check your configuration to see if it is correctly done. Does dmesg/journal show anything helpful regarding this other than the few lines you sent?

Regards,

Hola Samanta,

Gracias. I already attached in my question-mail the dmesg info about enp2s0. I am with the ugreen-dock in the network and it works fine with wlan0, too.

Only the enp2s0/yt6801 is not working, respectivly not stable, because it is up, down up and then final down...

Saludos

Hello, Mike
As mentioned, if the kernel has been updated in your last updates, you should try to revert to the older kernel and see if that fixes the issues

Regards,

Hola Samanta,

unfortunately this is not an option...

saludos, Mike

Hello, Mike
You can try installing an older kernel(if your kernel was updated when updating the other day! if it didn't then this might not be needed) if you can't select an option to downgrade properly, I will link you how to downgrade the kernel from the arch wiki: https://wiki.archlinux.org/title/Downgrading_packages

You can check your pacman logs in `/var/log/pacman.log` and see what was installed/updated and figure out if any package was the issue, if that was the issue

You can check with `ethtool enp2s0` what is the current configuration of the interface, and it will tell you if you need any extra network configuration for that interface

Regards,

Hola Samantha,

Gracias, That would be a big effort for a small driver-issue.

Strangely enough after de- and reinstalling the LTS-Kernel it looks like the DKMS Headers where rebuild correctly and anp2s0 is now working again. (with exactly the same network-configuration). It was a DKMS-Driver-Issue....

“When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.”

Thank you for your support. By the way it is running with 

 yt6801-dkms 1.0.31-2 from AUR

Hello, Mike
Glad to hear you got it working
That driver from AUR is not supported by us, so it will not get any updates from us, we recommend using the slimbook-yt6801-dkms package instead
In any case, when Linux 7.0 releases, this driver won't be needed as it is built-in within the kernel

Regards,

Hola Samantha,

Gracias for the hint, however:

That driver from AUR is not supported by us, so it will not get any updates from us, we recommend using the slimbook-yt6801-dkms package instead

is not working in the current configuration with the 6.19.8-arch1-1 (64-bit) Kernel.
