This Tutorial is meant for everyone, but realistically I will need to refer back to this in the future since I spend a day missing around with this card.

1. Install your NIC and boot up the server
2. Type lspic | grep Realtek. (Make sure the system detects the NIC)
3. apt install build-essential && apt install pve-headers-$(uname –r)

4. Go to Realtek's website and download driver version 9.011.00 and move it to your server
5. Type tar -xvf r8125-9.009.02.tar.bz2 (or whatever the name is for you)
6. cd r8125-9.009.02/ (make sure the autorun.sh is executable)
7. ./autorun.sh
8. Reboot and enjoy

Wow, you just saved me a bunch of time and effort (put the quad-port version of the same IOCrest card in mine today) :)
 
Hi everyone,

Can I still use the driver for Proxmox VE 8.1 (due in the 4th quarter of 2023), which is based on the 6.5 kernel? I've been having trouble getting my RTL8125B to work. It keeps showing that the link is down.
