How to Choose a Wi-Fi Extender for Xfinity in 2022?

You may still have some questions about choosing a WiFi extender compatible with Xfinity. What wifi extender works with Comcast products? Which features should I prioritise?

Make sure you consider all of the following factors.


Measured in square feet, the range is how much of a ‘surface area’ your extender can boost your connection by. If you live in a large space and you need a way to repeat your wireless signal to all of your rooms, you need to consider the range even more than someone who is just trying to fix a couple of small black spots.

Single or Dual Band

More and more modern WiFi extenders are dual-band. They work more efficiently by repeating signals onto two different bands, meaning less interference and usually better speeds and reliability. All three of the models on this list offer dual-band functionality.

Mbps Speeds

This is a measurement of how much data can travel the connection in a set time. Megabits per second, to be precise.

The higher the rating, the better, as it will give you a better chance of supporting the speed of your connection, but keep in mind that an extender doesn’t make the connection itself faster. It only supports and ‘relays’ the speed your network can create.

The TP-Link extender above can transfer speeds up to 1300 Mbps on 5GHz networks, more than enough for most users.

Number of Devices

Many of the WiFi extenders will limit the number of devices, or have a recommended maximum. If you’re working in an office, or you just have a home full of tech-lovers, keep in mind the fact you won’t be able to connect limitless devices.

Most of the WiFi extenders allow at least 20-30 devices, so most families will have enough capacity to use their tablets, phones, and laptops.
