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.
This worked for me as well. What was key though was re-booting the Xfinity Modem, not necessarily the router as that did not fix for me. It’s key that you re-activate the Xfinity account through the xfinity site with the code as part of the process. All other attempts without that step failed for me.
I tried this (sort of). I uninstalled the xfinity stream beta app from all of the TVs. I did a reset of the modem by holding in the reset button on the back. Waited until it came back up. Reinstalled the app on one of the tvs. Still not working!!! I am now on hold with xfinity again for the 3rdtime in 2 days. Should I have unplugged it? Would that make a difference rather than just resetting? All my other apps (Netflix, Prime video, etc.) are all working. Please help! I am beyond frustrated with this issue.
