Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
Can you confirm that the Advanced Wireless Receiver (AWR) is plugged into the Roku devices? Have you tried disconnecting everything and plugging it back in to make sure the connections are firm?
If you are still unable to resolve the issue, please send me a PM (private message) with your Roku account email address, and include the serial number of the Roku device from Settings>System>About along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
