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.

But, for the most part, Xfinity's cable internet is more reliable. CenturyLink may be cheaper, but Xfinity has more plan options and faster speeds, making it better in terms of long-term value.
