yeaah i had this issue, i think its the intel tech that forces your pc to update or whatever it wakes up your pc from sleep or even from full shutdown its wierd, try this:
go to Computer -> properties -> device manager -> check on network adapters
find your adapter wireless/ethernet
go to its properties and check power managment and uncheck anything under Wake on Lan
and see how this works out
i know its weird but it happened to me once i upgraded my PSU idk why xD
hope this helps it fixed it for me
