Realtek NIC (r8169 driver loaded) terrible speeds

So I've jsut installed proxmox 9.0.3 on my HP Elitedesk hp 705 g4.

Hardware:
  • CPU: Ryzen 5 2400GE
  • NIC: Realtek RTL8111/8168/8211 (onboard, PCIe)
ProxMox host loads r8169 driver and with this driver I barely get speeds up to 42 KB/s.
If I use USB NIC (which is Realtek RTL8153) everything works perfect. But I kinda want to use onboard NIC anyways.

Ethernet port worked perfectly fine before when this machine was running Ubuntu.

I've tried to install r8168-dkms from debian non-free bookworm repo, but install fails. DKMS fails with status 10. I've disabled secure boot, but still cant install it.

Is there any workarounds or solutions to this problem?
