Recommended NICS to use in proxmox

[13RodrigoM]

Good morning,

I am looking for a network card to install to my proxmox server. After investigating, the realtek NICs give a lot of problems to install in proxmox, so I don't know what network cards I could install in my server. I currently have an AMD Ryzen 5 5600G processor, running proxmox-ve: 7.3-1 (running kernel: 5.15.83-1-pve). Do you know how to check the compatibility of a network card with proxmox before buying it?
I need a 2.5 Gbit network card

thanks in advance

try kernel pve-kernel-5.19 or kernel pve-kernel-6.1

try kernel pve-kernel-5.19 or kernel pve-kernel-6.1

what improvements does it bring? My proxmox does not have a kernel to update

Its opt-in.

what improvements does it bring?

See here:

For example better support for newer hardware.

Hello!

I upgraded the kernel to 6.1. After installing a PTR-FU network card (RTL8125B) my main network card stops linking once the kernal boots and it is not reachable by the network, however it has the same IP as before. Any idea what it could be? Do you know if PTR-FU (RTL8125B) is compatible with my current kernel version?
