[SOLVED] Losing connection on all devices connected to router

[phool]

Hello there,

my problem is kind of weird which makes me believe I must have done something terribly wrong!

Currently I have two computers connected to my router. One of them is my desktop pc, the other one is being used for proxmox ve (6.4).

As I just started out using proxmox ve I followed this guide to setup proxmox + home-assistant: https://community.home-assistant.io/t/installing-home-assistant-using-proxmox/201835

But when I started the vm I noticed that can't access any website on my desktop pc anymore. It's not exactly disconnected from the internet since I still am online on discord or youtube continues to load the current video. But if I refresh any website or restart discord it will behave as if I'm offline. The server on the opposite is still online (tried to ping different adresses). After that I re-installed proxmox multiple times with no change. I always lose my internet upon starting a vm (with no media, bios set to ovmf).

I can only assume it has to be something with dns/gateway? I use 192.168.0.1 for both (same ip as my router).

Hopefully someone can tell me what to do.

I found the issue. When I first tried proxmox on v6.3 everything was fine, but then v6.4 came out and I figured i could just start from scratch with v6.4 since I haven't done anything important, yet. But I just figured the boot order on new vms puts net0 instead of scsi0. I don't exactly know why net0 would make my router crash, but everything works now! I would still be interested in an explanation if possible on why this might have happened on net0 though.
