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.
Did you restart your Roku device before re-installing the channel? That step is crucial when performing the troubleshooting. If you haven't tried the suggested order (remove > restart > re-install), we would recommend giving it a shot once again. We also suggest doing the restart from the Settings menu by navigating to Settings> System> System restart.
If you are still experiencing an issue with channel playback, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Re: Xfinity buffering and stoppage (and other channels too)
OK, I finally after many hours/DAYS of doing this and doing that and replacing equipment got the fix. Home mesh system did it. I purchased (not to advertise) the Netgear Orbi home Mesh system as suggested by the comcast Tech that came to my house and replaced all the cable and connectors. Good Luck everyone.....this was the best one I had yet. I just get the impression it's all about how can we find ways for the consumer to spend more money.
