The Netgear Nighthawk CM3000 is a DOCSIS 3.1 cable modem built for multi-gig cable plans. It has one 2.5 Gbps Ethernet port and two 1 Gbps ports that can be combined through link aggregation, so it can feed a fast router or a wired device without a bottleneck. It suits households on 1 Gbps or faster cable tiers who want to stop renting a modem. Against rival multi-gig modems it stands out for the 2.5G port at this tier; the trade-off is that it is a modem only, with no Wi-Fi and no phone port.
