Network Issues after updating

[Kaoplo]

Hello Proxmox Community,

I have recently updated Proxmox VE from version 7, to 8, I performed a clean install, and did not retain any previous applications, configs, etc. I am now running into an issue where the system drops the connection to my network every 30 minutes or so. The only fix I know of right now is restarting the node or waiting ~30 minutes, none of which are ideal. This has to be an issue with my network configuration or Proxmox VE 8, since I am unable to replicate this issue on other distributions.
I have looked at dmesg, journalctl logs, but none of them give any hints to why this could be happening, If requested, I can post them here, along with any other files that could help solve the issue.

My system is a Mac Mini late 2012, it's a weird machine to run proxmox on, but it has been working fine up until now.

Hi,

Could you please post the network configuration `cat /etc/network/interfaces` and the output of `ip a` and `lspci` commands?

Sounds like a sleep/power-save problem.

Hey there,

Here's the contents of `/etc/network/interfaces`:

auto lo
iface lo inet loopback

iface enp1s0f0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.11/24
        gateway 192.168.1.1
        bridge-ports enp1s0f0
        bridge-stp off
        bridge-fd 0


source /etc/network/interfaces.d/*
