Internet works on wifi, live ISO and Windows laptop but wont work on ethernet on current system

Hello @xalexander :wink:

What makes you believe that it is not working? According to your inxi output it is correctly detected…

Worth a try would be installing r8168 and blacklist r8169.

pamac build r8168-dkms

and create blacklist.conf at /etc/modprobe.d/ wiith the content:

blacklist r8169

After reboot, check again with which driver is in use with inxi and if it is working.
