If you are on a corporate network or in a "group policy"-controlled environment and were unable to find a solution after reading our Miracast troubleshooting articles for AirServer Universal and AirServer Windows 10 Desktop Edition, there can be additional causes for Miracast discovery or connection problems specific to your environment:


  • Check if you are able to mirror via Miracast on a Windows 10 computer while the sending device is not connected to any Wi-Fi network. If this works fine, there is a problem with Miracast-over-Infrastructure and your network will need additional configuration. Please check the required port openings for Miracast (AirServer Universal or AirServer Windows 10 Desktop Edition).


  • Make sure that the CastSrv.exe and WUDFHost.exe¬†Windows applications are allowed to pass through any firewall that might be installed on the client- and server-side. These are required for Miracast.


  • If you manage your environment using group policies, there is a policy that could prevent Miracast from working properly:
    • Go to "Computer Configuration > Windows Settings > Security Settings > Wireless Network (IEEE 802.11) Policies".
    • Open the setting for wireless policies.
    • In the dialog box, choose "Network Permissions"-tab and select "Allow everyone to create all user profiles".
