I have a very similar problem, not sure if it is exactly the same as described above:
My Fairphone 3+, just have it since some weeks, always disconnects from wifi for 2 or 3 seconds, then reconnects immidiately. This happens around two times per hour.
For some use cases this is not a big deal. But for me this is a huge problem:
- Disconnect and reconnect from Chromecast all the time.
- Interrupting SSH-connections and downloads.
- Streaming music is interuppted.
And much more.
Some details: I am using 2.4-GHz networks only. It happens with bluetooth turned off or on. It happens in different networks / with different routers.
Phone was shipped with Android 10 and it happens in all versions / updates since then.
I have contacted the support, but it seems like they have to deal with a lot of bug reports recently and had no time yet the answer.
But if somebody has an idea to fix it: Would be very appreciated, as this bug is driving me mad and makes the phone impossible to use (except regular phone calls).
