After update to kernel 5.14-18/5.15-2, my ethernet cannot be enabled. The RJ-45 line has plugged, ethernet opened in network settings but I can only connect to wifi.

I have searched for Archwiki but I use Intel, not Realtek.

After multiple reboot between windows and manjaro, installed linux-514-headers e1000e-dkms, tried solutions from here, it miraculously worked, although:

I have an Intel i210 network adapter and it works without problems.

4

I did a reboot, and it crashed again…

It cannot automatically start when booting.

@Keruskerfuerst I know, all works without problems except me

I work without problems in Linux 5.14-10 too

5

Then keep kernel 5.14 installed.
