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.
Netflix stuck at buffering since I connected to new smart TV. Internet provider and Netflix say it's not a problem on their ends. Netflix works great if I unplug Roku or restart router but the problem returns next day.
We'd also recommend following up with your ISP again to see if they can investigate the device's connection inside your wireless router, and see if something may be amiss with your DHCP settings, etc. that is causing the device to lose it's connection, etc. after a period of time.
