Arch linux does not bring up the network card at boot (wired)

When My machine boots, it fails to start the network, it just does not start. I [belive I] have narrowed it down to the simple fact that Arch Linux does not bring up the network card at boot.

journalctl -b -u netctl@my_network

the my_network file (has not changed since I installed arch linux)

Interface=enp3s0
Connection=ethernet
IP=dhcp 
## for DHCPv6
#IP6=dhcp
## for IPv6 autoconfiguration
#IP6=stateless

I then run$ ip link set dev enp3s0 up

and the network is up and running, I can read the news, enter this post and everything else .

It is a bit of a drag having to bring the network card up manually everytime, I even re did the install network again it worked ONCE, then back to not starting again.
The problem is that it does not bring up the card, and I do not see how to fix this. Everything that I find is for wireless, this this is for wired network.

I have been banging my head on this for days now, and I can't find a solution (maybe it passed me right by).

If there is some output missing, let me know and I will add it.

Re: Arch linux does not bring up the network card at boot (wired)

According to the Beginners Guide If you want to use the dhcpd service
through systemd you don't need a network management service, just enabling dhcpd.service should do the trick.
Also using two services at the same time for this usually will not work. Either it is dhcpd or netctl.
