dns probe finished no internet on all my devices

[pambroise]

So basically I have this problem where every 20mins, hour or sometimes more I get disconnected on all my devices, but only the dns, so I can't open a new tab but if I'm in a discord call it might still work for a few minutes before it crashes.

I can solve the problem by disconnecting and reconnecting to my wifi or unplugging replugging ethernet

I thought it came from my router so I made my provider change it, but it's the same.

Also, my pc doesnt connect automatically to the wifi for some reason.

Sometimes when I restart the router it works better for a few hours, sometimes not.

I tried using different dns but it doesnt seem to do anything.
