Control an Xfinity X1 Cable Box and Other RF Devices with a Samsung Smart One Remote

Normally I would not write a post about something so mundane as configuring a remote for a TV, but this was difficult to figure out. There appear to be quite a few people searching and posting on the Xfinity and Samsung forums, Reddit, and other places, but I wasn’t able to find the actual answer anywhere. Once I figured it out, I thought it would be nice to share how it is done.

The newer Xfinity cable boxes have the X1 voice remote and these controllers are radio frequency (RF) based rather than IR (Infra-red). Most of the various models of Xfinity cable boxes do still have traditional IR ports, but the target window is extremely small and hard to hit. If your model has one, it is located in the bottom right hand corner. Even if you do have an IR port, the functionality isn’t very good. Your Samsung smart TV’s hub and universal guide will struggle to control the X1 media options. Many of the proposed solutions on-line involved purchasing an IR relay, but you don’t need to.

The Samsung Smart One remotes are RF capable. The option isn’t enabled and doesn’t show up in any of the menus by default. Not only that, the setting is buried in the network menu for your TV of all places. To get there turn on your TV and hit the Home button on your Samsung remote. Scroll all the way to the left and select Settings.

Go to General, then pick Network.

Finally, click on the Expert Settings option and enable Power On with Mobile and IP Remotes.

Assuming that you’ve already got your cable box plugged in and setup as a device, use the back button on your remote to return to your home screen. Now hit the home button on your remote again to bring up the menu. Scroll to the left until you get to Source and go up to that menu. Scroll all the way to the right until you get to Universal Remote and select it. Select your Comcast device and at the top of it’s menu you will see an option to Enable RF Remote now. Click it and follow the instructions to pair your remote.

If you haven’t already configured your Comcast Xfinity cable box as a device, follow the same path except click the New Device option in the last menu to start a wizard that helps you choose your provider, enter your zip code, pick your HDMI input and so on. Skip the channel test. Say OK on the first option even if the channel doesn’t change. Then use the Universal Remote menu again (as described above) to get to the Enable RF Remote option.

Once you have it setup the Samsung One Remote should be able to control all of the functions of your Xfinity X1 device. You can even setup Google or Alexa and use it to operate your cable TV system instead of the voice remote itself.

  1. Hi, thank you so much for making this really helpful guide! I’m having this exact problem with my Comcast box and my smart tv. However after following the directions, when I go to the universal remote setup and select the Comcast box, no RF remote option shows up. Do you have a possible idea of this problem? Keep in mind my TV is a 2020 Samsung 7 Series. If you don’t have a solution, that’s fine too, just asking. Thank you 🙂
