That "without a video subscription" phrase seems to imply that you don't have a video subscription with Xfinity, or that you're not successfully logging into it. Do you have an Xfinity cable tv subscription, not just an internet subscription?
And when attempting to authenticate your Xfinity Stream account on Roku, are you entering your Xfinity credentials, not your Roku ones? Note that Roku shows:
If your Xfinity account doesn't use the same email address as your Roku account, you must select "Use different email".
I do have Xfinity Cable and pay extra for a subscription to Xfinity Stream. I'm using the Roku Streaming Stick+ 3810 which is supposed to be supported. I am able to install the Xfinity Stream app onto my Roku stick. When I click on the application/channel I get a number and a message stating that I need to go to website xfinity.com/authorize. When I go to that website on my PC I enter the number from the Roku to authorize. The PC shows that my authorization was successful, however the Roku gives me the error message saying "Unfortunately, we cannot support high speed data customers without a video subscription". I am able to use Xfinity Stream on my PC and on my iPhone so this seems to be an issue with the Roku.
Hi anderfam,
Sorry to hear about the issue. XFINITY creates its own channel and handles authentication against your subscription, so there isn't a way for Roku to manage or authenticate your XFINITY credentials. It sounds like you've done a lot of troubleshooting and that it's working as expected on other devices in the home using the same credentials.
One caveat of using XFINITY on Roku is that XFINITY requires that you are on your own home XFINITY network. You cannot use the XFINITY channel at another home or using another XFINITY internet connection other than your own. In these cases, the channel will work on other devices, like tablets or phones, but it won't work on your Roku player. Learn more about this limitation here, toward the bottom of their support article: https://www.xfinity.com/support/articles/activate-xfinity-tv-app-on-roku
Keep in mind using an extender in the home or any networking VPNs, proxies, ad blockers or anything else that could be segmenting traffic could throw the same error. Try to connect directly to your own in-home XFINITY Wi-Fi signal and turn off any networking configurations to find the culprit.
Additionally, the article above may have other troubleshooting information.
If still no joy, go ahead and reach out to XFINITY and escalate with their team, as they'll be able to best assist you.
I'm going to mark this post as solved as we've come to the end of our troubleshooting options but I hope the information above is helpful, and please follow up here if you find any other solution so that others could benefit.
i have experienced teh same error. but what's odd it is worked like a champ for the past six months or so and then just this past wednesday, I got the authentification error. had not for months. But only on Roku, not on any other device ... in fact the xfinity tech told me to ditch Roku and get a fire stick, he's so many intermittent issues .... About to return my brand new Roku Express to Walmart that I was hoping would fix the issue as I had a Roku 3 from 2014, but alas, it was not fixed.
had multiple tickets open with Xfinity and Roku - no resolution. Seems like instead of pointing fingers at each other, they should talk. In the meantime, ditching the Roku which hurts as that's what we used in 2014 to originally 'cut the cord'
Today, browsing the Xfinity forum, I see someone complaining that Xfinity Stream is not working on his Fire device, but is working fine on his Rokus.
Also, on the first page I see other posts complaining that Xfinity Stream doesn’t work on IPhone, Firestick, Chrome, Firefox, Samsung TV, LG TV, Android devices, and Apple devices. One guy has had several Xfinity tech visits and replaced his modem twice, replaced outside wiring, and after all that, the latest tech said the problem was “the app”.
So… if you change platforms, don’t be too surprised if Xfinity’s app remains glitchy on the next platform as well.
I'm having the same problem.
