Comcast Xfinity on Monday announced a new modem-router, called the xFi Advanced Gateway, which supports Wi-Fi 6E, the latest generation of Wi-Fi that can take advantage of the 6GHz spectrum band.
That said, no-one can change the laws of physics, and some houses may be too big, or have a particular design, meaning they can’t be perfectly blanketed in Wi-Fi from one single point.
