Hello @xalexander
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.
