I'm not sure if I'm missing something here.  We purchased a Microsoft Wireless Display Adapter, and it appears to be working.  The issue we are having is when my laptop is connected to the wifi network (LAN), it doesn't find the wireless adapter.  If I disconnect from the wifi network, it finds the wireless adapter and connects fine.  It appears that my laptop isn't creating a Wifi Direct connection when searching for the Adapter and therefore can't connect to the wireless adapter unless the wifi is disconnected and therefore available.  Does anyone have experience with this, and ideas?

I haven't yet tried other laptops, but we did test with an Andriod phone, and that connected fine, and was also connected to the Wifi (LAN) at the same time. The laptop is Windows 8.1, and appears to be miracast compliant. (the search for wireless display button is available)

Thank you!

can't connect to the wireless adapter unless the wifi is disconnected and therefore available.

What about after it is connected, are you saying that you can resume Wi-Fi then?  If not I would suspect interference from the two sources of wireless packets.  Supposedly there are some "channel" changes you can try on the Wi-Fi side but I haven't seen any such flexibility on the WiDi side.

Good luck

Hi russds,

Is the machine up to date? Have you tried to plug in with different USB ports to have a check?
We can test the Microsoft Wireless Display Adapter device with another machine to have a check if it is possible.

In addition, we can take the following steps to have a troubleshoot.
1.Reinstall the Microsoft Wireless Display Adapter driver from the device manager.
2.Run the built-in troubelshoot tool to have a diagnostic.

Have you removed and reinstalled the wireless adapter driver? Your wireless adapter and the adapters support for Wi-Fi Direct are highly suspect from the description youve provided. It is although your wireless adapter is unable to make simultaneous connections to Wi-Fi Direct and your wireless network.

As you suspect there is something specific to your notebook, you may want to provide the make/model of your notebook and the wireless adapter so that the community can potentially respond to device specific considerations.

Yes, this is where I'm headed.  I've now tried other laptops, and it works fine.  There seems to be something with my laptop/wireless card which doesn't allow for simultaneous Wifi connections (one regular wifi connection and one wifi-direct connection).  

Device Manager says my wireless card is a "Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC".  

Would there be any settings in the Wifi card properties, or anywhere else I might start looking for why my card doesn't seem able to do simultaneous connections?

Thanks!

That chipset is unfortunately not certified for Miracast as far as I can tell... https://www.wi-fi.org/product-finder-results?sort_by=default&sort_order=desc&keywords=RTL8723AE the Miracast spec doesn't require a simultaneous Internet connection as far as I know -     I'd be interested, just as a sanity check, what the results might be in a location other than your office. I would expect it to fail.      If you have a USB wifi adapter around, you MIGHT be able to experiment with having two wifi adapters connected. I have not done this so don't know for sure what the results might be.
