Our take on the Netgear Nighthawk CM3000 DOCSIS 3.1 Cable Modem

The Netgear Nighthawk CM3000 is a DOCSIS 3.1 cable modem built for multi-gig internet plans. It has one 2.5Gbps Ethernet port plus two Gigabit ports, and link aggregation can combine the two Gigabit ports for up to 2Gbps to a router or device. It is a modem only, so you still need a separate router or mesh system. That makes it a fit for people on fast cable plans who want to stop renting a modem and pair it with their own Wi-Fi gear. Against rival DOCSIS 3.1 modems, it stands out for the 2.5G port and three LAN ports, but it lacks built-in Wi-Fi and phone service.
