Why are keys on a Logitech Advanced MK540 wireless keyboard under Windows 11 temporarily not working?
Why might the keys on a newish Logitech Advanced MK540 wireless keyboard (with mouse and USB dongle supplied) suddenly become highly unreliable/ineffective, sometimes for about half an hour, even after switching it off and on, changing batteries, removing and replacing the USB dongle, checking wifi to whole of Windows 11 PC's area (still showing all 5 indicator levels)? (And there is no microwave working anywhere nearby — I've seen this other Super User question as well…) Sometimes the problem starts gradually, with some keys failing to be registered on screen and subsequently all keys becomin
