hi @yfanthenial, @jayeff
i have suffered from this problem after some windows update. this issue irritate me when i play the game. i have applied the tons of the solutions but any kind of solution not working.
one day i decided to check the physical connection of the drivers.
i changed the location of my SSD to second slot of the motherboard.
i dismantled the WIFI & BT driver, and cleaned the connections of the driver, after that i have again installed the physical diver to the mother board.
guess what i got the permanent solution.
after that WIFI & BT never disappear again.
