Ethernet not connecting even though plugged in

Hello, I just installed manjaro and the wifi works but the ethernet does not. I’m very new to linux so I may need a more in depth explanation. I’ve tried to install the e1000e solution I found from a post from 2022 but it didn’t work. This also happened when I installed Linux Mint. I have the Realtek RTL8125 2.5GbE network card.

… and what would that have been?
(a link to what you refer to?)

The output of:

inxi -zv8

could be a good start as well.

So not uncommon…

If I recall correct - this is an onboard chip, often used on AMD based systems.

Please see this search - I believe you can find a solution
