Answer

Check the power settings of the PC. By default, Windows switches off such USB devices when they are "inactive".

Answer

I have exactly the same problem! Very irregularly, but it happens. Sometimes it doesn't find wifi after starting the PC. Unfortunately, I haven't found a solution yet.

Answer

Plug the adapter into a USB 3.0 port. Not 2.0, but really 3.0.
Also update the mainboard (especially USB) drivers of your PC.

Your data. Your choice.
