What’s Wrong With Your Xfinity App On Roku?

Q. I just signed up for Comcast’s TV service and the customer service guy said I could start watching my channels before the installer came, using the Xfinity app on my Roku. But I keep getting an error message when I try to watch one of the channels on the app. Can you help me? — Burke, Boston.

Burke, as you note, Comcast has an app on Roku called Xfinity Stream that allows you to watch the same channels that you subscribe to via your set-top. For example, if have the set-top connected to a living room TV, you could watch your Comcast programming lineup on another TV by simply connecting the Roku to the second set.

This a nice feature for Comcast subscribers who want TV in multiple rooms without paying for additional set-tops. The Xfinity app does not require an additional fee. (Note: The Xfinity Stream app is also available on smart phones and tablets.)

However, Xfinity Stream requires two things to work to watch live channels:

1. Internet service from Comcast;
2. One Comcast TV set-top installed and connected in the house.

You didn’t mention if you subscribe to an Xfinity Internet plan, but it’s needed to send the signals from the set-top to your Roku box, using your home wireless network.

On point #2, it sounds like the Comcast customer service representative got a bit ahead of himself. You can’t start watching live channels on the Xfinity app as soon as you sign up for TV service. You actually have to have the service (and set-top) installed. After that, you should have no trouble accessing your subscription channels on Roku.

Last point: The Xfinity app is available on the following Roku devices:

Ultra (4660), Ultra (4640), Premiere + 4630, Premiere (4620), Express + (3710 and 3910), Express (3700, 3900), Roku TV (5XXX, 6XXX: Models within the 5000 and 6000 range), Streaming Stick + (3810), Streaming Stick (3600 and 3800), Roku 4 (4400), Roku 3 (4200, 4230), and Roku 2 (4210).

  1. Comcast is going to charge the same fee as a cable card if you use this app on (Roku) once the beta test is over so just a way to make us pay for each tv you connect.

    • Can you expound on this?
      If using Beta, its ‘free’, if eventually using released version, comcast will be charging?

      If true, do you have any details on pricing, etc.

      Note: I am a full Xfinity customer and am trying to save some $$$ on HD DTA rentals/mo.

    The app is only free during its beta. Once released they’ll be a charge .no advantage to app if you have to pay.

    I never had a problem streaming on the Xfinity Beta Stream app with my Roku stick 3600r however cannot stream any content with my new 3800 4K HDR streaming stick. Anyone else having this problem?

    having a problem today not with the roku but xfinity beta stream error code 403-102
    It is definitely xfinity error code we cannot stream xfinity. I was told by the tech they “will: be doing maintenance 11-12-18 from 1 am to 3 am

  5. I have a roku tv and a roku box and neither of them are working for me the keep giving me the same error code of 403-102. How can I fix this?

  6. The Comcast tech actually recommended getting Roku to stream to my other TVs. I’m able to download the beta app and once the code is entered it says I’m successful however only my past on demand movie purchases come up. There’s no way to exit the purchases selection. Not enough buttons on Roku app to try to exit and choose another menu. Now the Comcast techs so far are clueless as to why it’s not giving the option to stream

  7. After upgrading my modem, none of my 3 Roku’s will stream Xfinity beta. They all stream Xfinity beta just fine before I upgraded. After several tries from Xfinity tech support restarting, rebooting and the like, they told me they were having an outage in my area which I took to mean they had no idea why they weren’t working. I am getting the error code of 403-102. Its not showing the Xfinity beta app that my Roku is connected to my home network which it is.

  8. its kind of a piece of crap – no voice search – only way to use it is to save as favorites – but guess what, that doesn’t work it seems

  9. doi…..simple answer to a simple problem….of course not

  10. Jp is correct. The app is very difficult to use due, imho, lack of number pad on remote. Navigating to a channel w/o entering a channel number is extremely awkward. Plus there are other tech glitches to numeorus and difficult to describe here. Plus loading and navigating is slow.

    If the charge for this app, I will not use it.
