Realtek NIC RTL8125BG driver issues

[prasadrd]

Hi everyone,


I followed all of your guides, but unfortunately, none of them solved my issue. Initially, I was facing timeouts similar to the original problem mentioned here. Eventually, my network interface started completely resetting, disabling and re-enabling within seconds. I suspected it might be an ACPI power-saving issue or something similar.


Today, I decided to reinstall Proxmox (I was using an old ISO image), and now everything works! I updated Proxmox but kept the kernel at 6.5.13-6-pve. Newer kernels might work too, but since this one works perfectly for me, I've pinned it.


Thanks to everyone for your suggestions—I've learned a lot over the past few days. I'm still a newbie, but this experience has been very educational.


My setup:
Optiplex 9020 SFF with a budget 4-Port 2.5G PCIe Network Card (RTL8125BG chip, 2.5 Gigabit Ethernet Interface Adapter)

Hey! What iso have you installed to work?
I have just bought a ASUS NUC 14 Essential Slim Kit with n150 and one 2.5Gigabit Ethernet.
After installing LTS I learned that it has this driver issue or whatnot...

Have seen so many ideas around but no clear instructions!

It's Proxmox VE 8.1-2.ISO While it's possible to install an older kernel using the latest ISO, it's generally not recommended, according to online sources.

Thanks a lot!!
Can I upgrade from 8.1-2 to LTS or should I get a new iso to upgrade it?

I'm running Proxmox VE on older hardware, so I don't plan to upgrade further unless I add new components. Since everything is working well, I've pinned the current stable kernel. I may test newer kernels as they're released, but I'll revert to the known working one if any issues arise, especially with the LAN NIC. The Proxmox VE setup itself is fully up to date, I'm just sticking with an older kernel for stability.

For your question.
I can't say that for sure. Try the kernel I used, if everything works fine, you can move on to the next kernel version. Just keep going until the NIC starts acting up.
