If you just set up your device to your DirectTV unit for On-Demand programming, you will first need to reconnect the Internet to your DirecTV Cinema Connection (even if you have had a previous Internet connection).
Press and hold INFO on your remote until the Info & Test screen appears.
Select More System Info > Scroll down the page until you see Network status.
You will then select the "Reconnect" option, or "Connect" if this is the first time.
