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.
