Windows Server 2016 TP5 which appeared at the end of April has a major flaw. It doesn’t work with wireless cards!
I use a relatively high-spec laptop as my lab machine. Not being able to get the wireless card working means no Internet access and makes activation a lot more difficult.
The June Cumulative Update KB3163016 appears to fix the issue. https://support.microsoft.com/en-gb/kb/3163016
Install Windows 2016 TP5. Then immediately install KB3163016. Install the Wireless LAN Service (needs a reboot) through Add Roles and features or
Add-WindowsFeature –Name Wireless-Networking
The Wireless LAN Service defaults to disabled so you’ll need to change the start type to automatic and start the service.
Then you can install whatever Windows features you need.
One thing I’ve noticed is that the wireless card doesn’t seem to keep its connection to the wireless network between reboots. Its an annoyance in a TP would be beyond aggravating in final version
