LAN keeps disconnecting

For the last week my internet keeps randomly disconnecting. Only reconnects if i reboot multiple times.
I am completely lost on why this is happening. The only thing I changed was i added a linux server to the network. My downloading has also significantly increased.

In sys logs i usually see this before it disconnects. Never had this problem before. The addesses are my devolos.

I am using Zyxel 5g outdoor router for internet
Nano pi r4s running openwrt/friendlywrt
devolo mesh wifi for access

I have tried different firmware and meddled with all kinds of settings. No luck. Im a noob and would appreciated any help i get.

So I have come to you guys for help as my last hope :sweat_smile:

This isn't however the WAN port, and wouldn't have anything to do with the internet disconnecting ...

Question is, does internet go down, or is it your (W)LAN that's the issue ?
Try taking the Devolos out of the equation..

Yes the internet is there, I just lose connection to it by lan.

I have a straight eth cable connection from my pc to a switch to openwrt. Bypassing the devolos. It loses connection as well.

I wish I could take the devolos out and test it. But I don’t know how long to wait for a possible disconnect and my family will throw a tantrum.

Is there something I can check for more detailed logs of what’s going on?

on the wired PC, try running a constant ping to the LAN IP of your router, and 8.8.8.8 in parallell.
see what dmesg reports after a network hick-up.
