Hi everyone,

I’m trying to install Proxmox VE 8.4 on a machine with an ASUS PRIME X870-P motherboard, which has a Realtek 2.5Gb Ethernet adapter onboard. Unfortunately, during installation, I get a “No network interface found” error.

The LAN port lights up, so the hardware is active, but Proxmox doesn’t detect it. I assume the required driver (likely r8169 or r8125) is missing from the installer.

Has anyone managed to get this NIC working on Proxmox 8.4?

Is there a custom ISO or a workaround to load the driver during installation?


Thanks in advance for any suggestions!

Hi,
you might want to try installing Proxmox VE on top of Debian then: https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm

If you would like to verify your suspicion/provide more information, you can run the installer in debug mode (select Advanced Options in the installer). After it fails, you can inspect the dmesg/kernel logs and installation logs in /tmp.
 
Thanks for the suggestion!

However, I’d prefer not to install Proxmox on top of Debian – I want a clean, native install.

Regarding debug mode:

Do you think it will show anything more than just a missing driver for the NIC? Or is it purely useful for confirming that?

How to install r8169 after proxmox started with usb Lan ?

Yeah, I ran into this same problem with the Tuf X870 Pro. The advice given to me was "just stick with Intel NICS." I think some older Realteks work but probably not 2.5Gb+. You'll have to geek out for a week trying to figure it out or "just stick with Intel NICS." I tried downloading the driver but it wouldn't install because make wasn't installed. Installed make and it still wouldn't install because the headers for the kernel don't support it. The ProArt X870E-Creator has an Intel NIC. I'm going to try that since I don't have room in my box for a separate NIC card.
