Our take on the Netgear Nighthawk Multi-Gig Speed DOCSIS 3.1 Cable Modem

The Netgear Nighthawk CM1100 is a DOCSIS 3.1 cable modem with a 2.5 Gbps Ethernet port, built for cable plans that go beyond 1 Gbps. It is a modem only, so you pair it with your own router or mesh system. Two Gigabit LAN ports let you connect a router and another wired device directly. Compared with DOCSIS 3.0 modems, it handles more downstream and upstream channels and is certified for major US cable providers, though it will not work on fiber or DSL.
