[SOLVED]Network interface only appears (and works) in usb installation
I have installed arch without issue, however my network interface (enp3s0) only appears while booting from the USB drive and therefore ethernet only works there. When I run ip a from within the usb installer it shows both lo (loopback) and enp3s0. However when I run it from the arch shell itself only lo appears. Any ping commands give me a connect:Network is unreachable. I cannot install anything via pacman.
My /etc/hostname and /etc/hosts are formatted according the installation guide, using 127.0.1.1 as my ip address. I am unsure of how to find my permenent ip address.
I have installed NetworkManager via chroot to /mnt, although it does not allow me to start it using systemctl start NetworkManager.service. (Failed to start NetworkManager.service: Unit NetworkManager.service not found.) I may have installed it wrong, I am not sure. I can't install anything directly to the arch filesystem due to the connection not working.
My ethernet controller is a Realtek RTL811/8168/8411 controller, with kernel modules r8169.
Are there any fixes, and is there anything I may have done wrong?

Did you install linux-firmware?

Re: [SOLVED]Network interface only appears (and works) in usb installation
A solution I am thinking of is reformatting all the drives but it might not change anything. In addition I could load a fresh install of arch onto my usb drive. Would that have a chance of fixing anything?

Reformatting the drives is not a solution.
See what the journal has to say.

I didn't mention it in my previous post, but I also planned on doing a fresh install after I reformatted everything. I did all that and now the network interface appears. Unfortunately I'm not sure what caused it in the first place, but it works now.
