Make sure you are connected to your network and the Internet. From the Roku home screen, select settings > network > repeat guided setup.

If you are connecting wirelessly, you may need to disable your wireless router's firewall setting, or create a specific rule that allows the Roku player access into (and out of) your wireless network. Details on changing the firewall setting can be found in the user manual for your router.

In rare cases, the inability to play movies can be the result of a hardware problem. If you continue to experience this issue, contact Roku Customer Support at 1-888-600-ROKU (7658).
