(AirMedia 2.0 only) Ensure the Wi-Fi adapter is enabled on the client device and that the
latest drivers are installed for that adapter.

Ensure the network is not blocking any of the Miracast related ports (7236, 7250) listed in
the
Firewall Settings & Port Table (on page 26)

Check for Miracast support on the client device:
1. Press

2. Select Save All information….
3. Open the saved DxDiag.txt and find Miracast. It should say Available, with HDCP.

Check the group policy settings on the client device. On domain-joined devices, Group
Policy can also block Miracast.
