Fairphone3+ wifi problems

Hello Fairphone3+ wifi problems

Now the wifi connection is also starting to interfere, I thought it was the router, but that’s not the case.

I have a connection for a while and then no more later I have to manually
reconnect to the WiFi network.

This is a well-known network by the way.

A new motherboard came in a few months ago
because the phone was also malfunctioning and then hung in
Fatbood Mode

I’ve had the Fairphone for six months now.

what could i do? send again? Guarantee?
who can give me advice?
