could be it has an issue with current kernel.  
You could try to boot on LTS kernel and uninstall the dkms driver…

You could try increasing the grub timeout to 10 seconds from 5. It was reported on the Arch forum as possible that it needs time to power up or it doesn’t load the module.

This is done in `/etc/default/grub`

Then update grub with `sudo grub-mkconfig -o /boot/grub/grub.cfg`

This is something you can check as it should use the r8169 module i think.
