Same issue here. My wifi (only in bootcamp) keeps disconnecting every couple of minutes or so in BootCamp. I have had my 15" 2016 for about 2 weeks now with no issues on wifi in MacOS. I have a lot of devices in the house and have no other wifi issues. I am using a single Apple Airport Extreme 4th generation (A1354) a/b/g/n router with the latest firmware 7.6.7. I installed bootcamp this morning with the intention of setting up a few games. The bootcamp drivers were installed properly and device manager shows Broadcom 802.11ac Network adapter. The driver version is 188.8.131.52. This is on Windows 10 Professional 1607. Bootcamp shows no updates in Apple software update. Right clicking in device manager and checking for a driver also shows it is up to date as of today.
