I recently installed Arch linux and everything is working just fine, except for the internet. After booting I always have to enter the following commands to make it work:
sudo ip link set enp3s0 up
sudo dhcpcd enp3s0
After that the internet connection works just fine.
I know I could just create a script that runs automatically after booting up, but I would like to know what the "nice" way is to fix this and why this is happening in the first place, maybe I did something wrong during the installation?
In case it's helpful, here's some info: (gathered after running said commands)
