Reformatted for mobile users:

Had the same problem with Raspi 4B. Problem was dependent on screen resolution (!!). With 1920x1080, wlan0 became disconnected after it was ok at lower screen resolutions. Was in 2.4GHz band. After turning on 5GHz in the router and going into the network preferences (right click the network icon top right on screen) and SSID ... and checking "automatically configure options" the connection remains stable (so far :D ).

This is a good reminder that every digital circuit is really a fancy analog circuit. Your program may be perfectly correct, but when it runs on faulty hardware, you are hosed no matter how many times you’ve formally proven it.

or even a perfectly functional hardware in presence of EM noise.
