Check Power

Check Connection


Make sure the AirTV device is connected to the internet and that your internet connection is active. Either the WiFi or Ethernet indicator light should be on.


Check Firewall


Check your firewall/NAT settings to ensure the device is not being blocked. Note: Customers using firewalls may be required to enable port forwarding. The TCP port is 5401. It is the standard SBSDK port. If the MAC address, the WiFi (active MAC) is found in the app, in the settings, and the Ethernet MAC is on the label.
