Beyond the TV, Xfinity Flex customers can also use the system for unique services like finding the Wi-Fi password, checking what devices are connected to the network, set parental controls, pause Wi-Fi access on the home network and automation tasks for checking and activating home security protocols.

How to set up the Xfinity Flex

First, make sure your TV has an HDMI port. Unpack the Flex and follow the steps. You can also watch the video below from CollectorKev explaining the procedure.

  1. Plug the the box into your TV’s HDMI port on the back or side of your TV using the HDMI cable that came in the box. 
  2. Note the HDMI port’s number., because if your TV has more then one HDMI ports you will have to select it. If you plan to stream movies and TV shows in 4K UHD or HDR, remember to select an HDMI 2.0 port that supports HDCP 2.2.
  3. Plugin the Xfinity Flex’s power cord to a power source.
  4. Flex will connect automatically to your Xfinity Wi-Fi 
  5. Follow the screen to set your Xfinity Flex installation.

If you plan to stream movies and TV shows in 4K UHD or HDR, remember to select an HDMI 2.0 port that supports HDCP 2.2. 

A great overview of CollectorKev. If you like the video don’t forget to subscribe to his channel.

Of course if your TV doesn’t support 4K you may not see all the benefits of using it. 4K TVs are really affordable and the price is down to $500 average for a good 4K TV.

At the Glance…

The deal includes an Flex box and Voice Remote at no additional cost of the Xfinity Internet service. It required that you use Comcast’s own modem/router combination, and it didn’t offer apps for services designed to replace the cable bundle.

If your TV support 4K and want to watch 4K content, but you are not an Xfinity customer you may look at this Roku Streaming Stick+ as the most affordable low-end Roku so far as you may concern. 



Xfinity Flex offers broadband customers something they can’t get from other wireline internet suppliers and the platform can be used to rent movies and TV shows. And users can also access Amazon Music, Pandora, iHeartRadio and XITE.
