    Crap. So many issues with this modem. Completely unreliable, apparently due to some firmware update issue between Motorola and Comcast. Continually drops the Internet feed. Stay away

    Gigabit internet and WiFi 6E are not part of average US home internet setups...yet. A 2.5gbps modem is akin to buying an advanced ticket to Mars on SpaceX. You're gonna be waiting around for a while until it's viable. However, future-proofing aside, it has a practical application. Comcast over-provisions their internet in many cases. So you may get higher speeds than what you pay for by using a more advanced modem like the one reviewed here.
