[Solved] Network ports stop working

I have a system that sat unused for a very long time. It's a custom built (not by me) system with several graphics cards and a decent amount of memory, but at some point in the past the network ports (x2) stopped working - when connecting the ethernet cables, no link lights appear. The fact that there are 2 physical ports and they both stopped working leads me to think that the problem is not with the physical hardware, but maybe with drivers, or OS configuration.

When I use the desktop GUI "network" under "settings" I get a pop-up saying:

"Oops, something has gone wrong. Please contact your software vendor"
          "NetworkManager needs to be running"

likewise if I use the command line "nmcli", it says:
          "NetworkManager is not running"

since I have no connectivity, using pacman just errors out.
can this "NetworkManager" be downloaded and installed offline?

Re: [Solved] Network ports stop working

if you can run nmcli then its already installed, enable the service

systemctl enable --now NetworkManager
