Like many others, I have been struggling with WiFi dropping out on the Realtek RTL8821CE on my new HP laptop. Like others, I have played around with drivers, power management settings etc.
After I uninstalled everything and did a factory reset, I could not trigger the WiFi drops like I could before. Not until I reconnected my Technet wireless mouse, at which point it returned consistently.
Changing my wireless mouse to an old Logitech M195 seemed to solve the problem for me. I have not been able to trigger the problem all afternoon since.
Just thought I'd post this in case it is of use to others.
Update: 24 hrs later, and the problem has returned, whatever mouse I use. Another dead end :-(.
