Does Fire TV Cube Work With Xfinity? How to Connect

The Amazon Fire TV Cube, which attempts to indulge users in the excellent Amazon Alexa ecosystem is a fantastic smart home inclusion to any home.

But its compatibility with other nonsmart home devices needs to be taken into consideration too, especially ones that can't be replaced with other products, like the Xfinity box.

This does beg the question as to whether a Fire TV Cube will work with Xfinity.

Second generation Fire TV Cube works with Xfinity TV box. Simply connect both the Fire TV Cube and the Xfinity box to the TV, and navigate to the Equipment Control option in the settings to pair both devices. First-generation Fire TV cubes don't work with Xfinity.

So with this article, I intend to find out and tell you whether one can connect their Xfinity TV box directly to their Amazon Fire TV Cube and make them work united.

Does Amazon Fire TV Cube Work With Xfinity?

The Amazon Fire TV Cube specifies a lengthy list of devices that are compatible with it.

Fire TV Cube Compatibility List

From the list, it can be derived that the 1st generation Amazon Fire TV Cube only supports traditional A/V receivers and TVs.

Amazon added support for Cable and Satellite boxes, along with soundbar support only for the 2nd generation Amazon Fire TV Cube and later.

So if one has the 1st generation Amazon Fire TV Cube, the Xfinity cable box might not be compatible working directly with the Amazon Fire TV Cube.

But the Xfinity Box is fully compatible with the 2nd generation Amazon Fire TV Cube, with full hands-free voice control support thanks to Alexa.

This compatibility criterion is one of the key differentiating factors between the 1st generation and 2nd generation Fire TV Cubes.

The Xfinity app is also available natively from the Amazon App Store on the Amazon Fire TV Cube.

That being said, since the input terminals used (HDMI specifically) are a universal standard, you can still connect the devices but it won't work integrated into the Amazon Fire TV Cube.

How To Connect the Xfinity TV Box To the Amazon Fire TV Cube?

Now that we have established that the Xfinity box is compatible with the 2nd generation Amazon Fire TV Cube, let's see how to connect them properly.

To connect the Xfinity TV box with the Amazon Fire TV Cube, follow these steps:

1. Connect both the Xfinity TV box and the 2nd generation Amazon Fire TV Cube directly to the TV, preferably using HDMI.
2. Switch the input on the TV to view the FireTV OS running on the Amazon Fire TV Cube.
3. Go to the Settings tab.
4. Select the Equipment Control option.
5. Choose the Add Equipment option.
6. Fill in the details asked by Amazon on the resultant page. These details may include the cable provider details and zip code.
7. Let Amazon do its magic and wait till the TV switches to the Xfinity box input source.
8. Confirm the switch has been made by pressing the fast forward button on the Alexa Voice Remote when prompted.

Once all is done, Alexa will confirm that the Xfinity TV Box and the Amazon Fire TV Cube are successfully paired.

This wipes out all temporary cache and user data and resets the Fire TV Cube back to when it was freshly unboxed.

One might need to pair their Amazon account again in order to use the Fire TV Cube after the factory reset.

You can invoke the voice assistant to do all tasks relating to the navigation of the Xfinity, and even seamlessly switch between input sources with just your voice.
