WiFI does not work on Windows 10 BootCamp - Drops in and out
Answer: Set the Power Output of the Broadcom 802.11ac Network Adapter to 25%



The solution was found with a Google search for "macbook pro wireless disconnects randomly bootcamp windows 10" which returned the following video as result 2 Fix APPLE bootcamp wifi drop out

My System: 


Macbook Pro 10,1 (Early 2013)
Broadcom 802.11n Network Adapter
Driver Version: 7.35.118.73


I have been suffering with slowly degrading WiFi connection over the last couple of months (approximately).  Recently, it has got the the point where the connection will drop out and reconnect 2 or 3 times per minute.  That was really only noticeable when using a VPN connection over Cisco AnyConnect - otherwise browsing just appeared to be very slow at times.  I found that disabling the WiFi and re-enabling it would provide relief for a few minutes.

Things I tried that did not work:


Installing later drivers (not signed by Microsoft) Broadcom_BCM43xx_7.35.317.3-Win10 accessed from Search for Broadcom 43XX drivers - result 1
Unchecking the "Allow the computer to turn off this device to save power" option on the Power Management tab of the Device Properties Dialog.


I hope this works as well for others as it has for me...
