Here is Comcast’s most advanced modem/router which promises speed as well as ease of use.


After realizing the challenges people face with their existing modems, Comcast established a goal to make their xFi modem/router easy to setup, easy to use, and easy to connect to the internet.

Fraser Stirling, Comcast's SVP of Hardware Development, had this to say. "I want your parents to stop phoning you about their internet connection."

And it seems that they may have accomplished just that with the interface of the xFi app. The app allows you to set up your WiFi, customize settings, create individual profiles and much more. You can even setup schedules to turn Wifi connection on and off all through the xFi app.

This xFi Advanced Gateway modem really excels in the speed department. The real trick was to create WiFi speeds comparable to or exceeding wired Ethernet connections.


The result is an XFi Advanced Gateway modem that utilizes an 802.11ac Wave 2 Wi-Fi standard, which allows for the possibility of gigabit WiFi. The problem with this working properly is obstructions like walls and floors. 

This Gateway is designed to work across large areas via the 8x8 antenna array, which consists of eight antennas to transmit WiFi signals and another eight to receive them.

The development team was able to achieve 1.2 to 1.3 GB per second speeds over WiFi in tests. These standards also support MU-MIMO (multiple input, multiple output), which provides connections for a larger number of devices more efficiently to a single network.

To increase coverage for large homes, Comcast is working on a mesh WiFi system for early next year. As of today, Comcast is making the xFi Advanced Gateway modem/router available in every market where they offer gigabit internet.
