Dragon RTL8125BG Ethernet port not working

So I bought a new ASRock B550 Extreme4 that has this ethernet port “Dragon RTL8125BG” which is Dragon 2.5G

Does not work whatsoever.

Seems there is no driver loaded.

you could try

sudo insmod /usr/lib/modules/5.8.11-1-MANJARO/kernel/drivers/net/ethernet/realtek/r8169.ko.xz

it says “could not insert, file exists”

Please try:

sudo mhwd -i pci network-r8168
sudo modprobe -r r8169
sudo modprobe r8168

nothing happens, it just says that the modure is not in directory im running manjaro on a live thumb drive at the moment.

Oke the r8169 should support this card (see: here ) could be that it also needs a the firmware file for that you could try.

pamac build realtek-firmware

should provide the correct firmware.

In the future, when providing code/output, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text so that the output looks like this:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

instead of like this:

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

(as that makes our life much easier so you get helped more quickly and efficiently)
