Miracast does not connect

This article applies to the following products:

Issue

Windows sporadically create multiple profiles per Miracast target device.

In our case, multiple profiles are created for a single Base Unit.

Solution

Run through this process to check if this clears your issue:

Check the registry for this entry, back up the entries and then delete them all, profiles will be recreated on the next connection.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SWD\WiFiDirect

If you have administrator rights on the PC also check and delete this entry if present.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Device Association Framework\Store

There are two more possibilities we have discovered:

  • FIPS 140-2 enabled in the wireless GPO profile may cause issues
  • Active Directory may block WIFI Direct. WIFI direct is used by Miracast
    • Run this OS command at a DOS prompt: gpresult /h c:\reports.html
    • Next, open c:\reports.html, then click show all at the top of the report
    • A search for WIFI direct will display what policy Active Directory is setting.
