Add A Wireless Display is Missing in Windows 8.1 and How To Get it Back


The pre-ordered Microsoft Wireless Display, a Miracast wireless receiver, finally arrived the other day. I was all excited trying to hook it up with my Surface Pro to see how it works out. I followed the instruction that tells me to:

  1. Swipe in from the right edge of the screen, and then tap Devices.
    (If you’re using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Devices.)

  2. Tap or click Project, and then tap or click Add a wireless display.

But the problem was, I don’t see the option that lets me to Add a wireless display under Project. All I see is a bunch of options to connect to the external display.

Charm - Devices - Project

So what am I missing here? Turned out, it’s one of the other network protocols bundled in Wireless adapter settings causing the problem. In my case, it’s the Deteministic Network Enhancer that’s interfering with the system.

So what is this Deteministic Network Enhancer? It’s a type of driver for supporting  VPN software’s for security and optimization of network traffic. It usually comes with the installation of Juniper and Cisco VPN client. That’s right. It’s this Cisco VPN Client I have installed on my Surface Pro that’s causing the problem.

After I deselect the protocol and hit OK in Wifi Properties, I see the Add a wireless display option appeared right away in Project Charm bar.

Things are a lot easier after that. After a few seconds, I have the new Microsoft Display Adapter showing up in my Project view waiting to be connected.

However, with Cisco VPN Client a must have on my tablet, I will have to flip the protocol option on and off every time when I need to connect to VPN or Wireless Display. I have to admit it’s annoying but unless there is a fix for it I have to live with it for the moment.

If you don’t have Cisco VPN on your computer but still don’t see the Add a wireless display option, take look the list of network protocols in your Wifi Network Property dialog box. Turning off the ones that don’t look necessary and see if it helps. As far as I know, VirtualBox is another one that’s confirmed having the same issue as well.
