I did everything as in the tutorial but I still have trouble connecting to wired on archlinux.
As you can see the connection is unavailable:
[isaac@dog ~]$ nmcli device
DEVICE         TYPE      STATE                   CONNECTION
lo             loopback  connected (externally)  lo        
wlan0          wifi      disconnected            --        
p2p-dev-wlan0  wifi-p2p  disconnected            --        
enp4s0         ethernet  unavailable             --    

also, the link is not detected, even though the ethernet cable is working and it was tested:
[isaac@dog ~]$ sudo ethtool enp4s0
Settings for enp4s0:
