You can try this first and see if it helps. Turn of power saving in Network Manager, you do that by opening the file manager and navigating to /etc/NetworkManager/
once there right click on conf.d and open as administrator change the wifi.powersave = 3 line to wifi.powersave=2 then reboot. If it does not help you can change it back. Good luck.

I discovered that my new phone kills the wifi for few seconds.
I switched the phone to 4G and that's stopped killing the wifi signal.
