The NETGEAR Nighthawk CM1100 is a DOCSIS 3.1 cable modem with two 2.5 Gigabit Ethernet ports, so it can feed a multi-gig router or two separate devices without a switch. It supports downstream speeds up to 10 Gbps and upstream up to 2 Gbps on networks that offer them, and it is backward compatible with DOCSIS 3.0. It suits people on a fast cable plan who want to stop renting a modem and pair it with their own router. Against single-port rivals, the two 2.5G ports and link aggregation are its main edge; it has no built-in Wi-Fi, so a router is still required.

Owners generally rate the CM1100 well for stable connections and easy setup with major cable providers. Most praise comes from people on fast plans who pair it with their own router; complaints center on activation hassles and units that needed replacement.
