Back Story: I built a new computer, using the MSI Z490 A Pro motherboard. It comes with a RTL8125 2.5G Ethernet Controller. I decided to install Ubuntu 20.04 for this build. This distro doesn't seem to come with necesssary driver for this controller. I don't have wifi either. If part of solution is tethering with bluetooth I could give that a shot, but I would prefer to learn with driver from usb stick if possible.
I have no Linux or programming experience, except a bit of front-end web dev., so you're dealing with a novice, but I started to read and learn about Ubuntu and linux, so far I got the thing installed and I'm getting to know commands, command prompt, terminal in general. I believe I would know how to get it going with clear step-by-step instructions, I have a generally good grasp of the basics of how its structured (if I qualify to say that, lol).
Typing in terminal
lspci -knn | grep Eth -A3
I get the name of my Ethernet controller, RTL8125 2.5G ...and also it shows at bottom: kernel modules: r8169.
Typing in terminal:
sudo lshw -C network
says:
network unclaimed
and shows Ethernet Controller RTL8125 info.
Here is the link to realtek website: https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software
On the Realtek website there is a driver for RTL8125 for linux. I tried following instructions, however they assume people are experts, or info ommited. But I got stuck on third step..
First step: unpack the tarball,
Second step: "Change to the directory: # cd r8125-8.aaa.bb"
Third step:
If you are running the target kernel, then you should be able to do: # ./autorun.sh
So I decided to make a new directory and put all content of driver(r8125-8.aaa.bb) in it.
New directory path: ~/Downloads/Drivers
Then I used chmod 777 in terminal to give executive permissions to all files from driver folder. Then I tried to do third step and didn't seem to work.
Is there something I need to do with NetworkManager directory? Should I make a new kernel module somehow? What about dkms? What does that have to do with this problem?
