Comcast Rolls Out of New Supersonic WiFi

Comcast has announced that Supersonic WiFi, enabled by its newest WiFi 6E gateway, is now available to Xfinity Internet Gigabit and Ultrafast customers across the U.S.

Supersonic WiFi is capable of delivering speeds faster than 1 Gbps, 3X more capacity, and the speeds of the future – symmetrical Gigabit speeds – to support hundreds of connected devices simultaneously.

"Our Supersonic WiFi is made to do anything so our customers can do everything they want online, and our latest gateway enables key features like speeds faster than a gig to power a house full of devices – all at once," commented, Sophia Ahmad, EVP and CMO, Comcast Cable.

Xfinity Internet customers connected nearly 1 billion devices in their homes in 2021 alone, a 12X increase from just a few years ago, increasing the need for faster speeds and more capacity.

Comcast’s most powerful device to date, the new gateway is a giant leap forward in both key connectivity areas, with three WiFi bands – 2.4 GHz, 5 GHz, and a new, 6 GHz band. Together, these WiFi bands reduce interference and increase bandwidth in the home by 3X to support the massive influx of connected devices used by consumers today.

Xfinity’s Internet also features xFi Complete, which provides customers access to a new Tech Upgrade program that will provide them with an updated gateway after three years and Advanced Security on the Go that protects customers’ mobile devices anywhere, anytime.
