oh ok so I shouldn't disbale it then ?
I fully understand you I am in germany too .

You just have to try it. I have a local provider who has already upgraded more or less everything with fiber and IPv6 and as soon as I disable the IPv6 support in the FritzBox my ping goes through the roof.

IPv6 is prioritized and the IPv4 only is converted to IPv6 via a tunnel. Therefore then the high ping with disabled IPv6 support in the FritzBox.

Same problem, Mikrotik router, WPA2 AES.
As work around I've created hotspot without encryption and add Mac address filtering only for phone. no problems with WiFi connection about a day

The same problem with me
also from Germany, with a FritzBox 7490.
With the FritzBox I unfortunately cannot filter the MAC address in the unsecured guest network, so the problem cannot be solved with me.
What I also noticed when the device is connected to the power supply is that this error does not happen.

I would have tested another router if I have but I only have FritzBox just like most people in Germany and buying a router just to test the problem is a bit stupid to be honest

Another observation I made today in my home office is that when I have an active upstream, the bug is not triggered. I streamed hours of music over Poweramp (Local saved music over the network. No stream from the internet) to my Google Home Mini and had no interruptions.

but every other device I have/had was working without a problem with my 7590. I have even tested my old OnePlus 2 in the last few day. It had no problems and all my other devices too. I can even reconnect me manually to my second SSID of the 7590 without restarting the WiFi of the Note. It has to be a problem with the software of the Note.

It does not even notice that the internet connection of a WiFi network is down. I tested it with my router. Dialed into Wi-Fi. Disconnected the Internet on the router and there was no message that the Note wants to switch to the mobile data because the WiFi connection has no Internet access anymore. This should be the default behaviour of an Android system when this happens, but the Note does nothing in this case.
