Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.

Talk to your TV provider about their timeout settings. Same as you get logging into websites and checking the "remember me" button. Has nothing to do with the Roku itself. Mine stays activated much longer. Same model as OP.
