I'm following this guide

https://github.com/awesometic/realtek-r8126-dkms

when i lunch command "sudo dpkg -i realtek-r8126-dkms_10.014.01-1_amd64.deb"

I get this

The Kernel headers are not installed. Install them with apt install proxmox-headers-6.11

SOLVED!! (tested with kernel 6.8.12-6)

I have ATOMMAN X7 Ti with 2x 5gb Realtek 8126 card

procedure step by step:

1) wget https://github.com/awesometic/realt...01-1/realtek-r8126-dkms_10.014.01-1_amd64.deb

2) apt install sudo

3) sudo apt install --fix-broken

4) sudo apt-get install build-essential

5) sudo apt-get update

6) sudo apt-get install dkms

7) apt install proxmox-headers-6.8.12-6-pve

8) sudo dpkg -i realtek-r8126-dkms_10.014.01-1_amd64.deb



9) echo "blacklist r8169" | sudo tee /etc/modprobe.d/blacklist-r8169.conf

10) sudo update-initramfs-u

11) type "dkms status" for check if the driver 8126 has been installed correctly



12) apt install net-tools and type ifconfig -a for check that the network cards are correctly recognized



13) type "lspci" on shell for for check that the network cards are correctly recognized and driver 8126 has been installed correctly

14) go to proxmox -> network -> vmbr0 and add the name of the two network cards to "bridge ports" section (they should be enp86s0 e enp87s0)





15) apply configuration in the tab and reboot

HAVE FUN


IMPORTANT !! remember that if you update the kernel you will also have to update proxmox-headers-6.8.xx-x-pve

Thanks mate you solved my issue.

This line was not needed for me: sudo update-initramfs-u

As you mentioned I had to use: apt install proxmox-headers-6.8.12-8-pve

I seem to still have an issue with this nic even though it works. Testing from the proxmox host with RTL8126 with iperf3 to my nas and windows machine i get a solid 4.7Gbits in one direction and between 400-500Mbits in the other direction. Anyone have a clue? It seems to have single RX/TX queue, incomplete RSS support
