The Microsoft Wireless Display Adapter can communicate with devices on either the 2.4GHz or 5GHz wireless frequency bands, but you must have the 2.4GHz band enabled on your device when you’re pairing your device with the adapter.
Here’s how to enable the 2.4GHz or 5GHz band:
In the search box on the taskbar, enter device manager, then select Device Manager from the list of results.
Expand Network adapters, then right-click your device's network adapter. For example, either Marvell AVASTAR adapter or Qualcomm Atheros QCA61x4A Wireless Network Adapter.
Select Properties > Advanced.
Note: If you don’t see the Advanced tab, you aren't logged in as an administrator. If this is the case, select Change Settings, type your administrator password, and select Yes. Then you'll be able to select Advanced. If you're an administrator on your device, the password should be the same as the password you used to set up your device.
Under Property, select Band.
Under Value, select the arrow and select Auto > OK.
