Netgear Nighthawk CM3000 vs NETGEAR Nighthawk CM2000

Both are DOCSIS 3.1 cable modems from Netgear's Nighthawk line with a 2.5Gbps port, so the real split is ports and headroom. The CM3000 adds a second Ethernet port and link aggregation, which suits a household wiring more than one device to the modem or wanting a backup path. The CM2000 is smaller, lighter and simpler, and owners report it holds a stable connection on gigabit plans. Buy the CM3000 if you run multiple wired devices or want the extra port; buy the CM2000 if one fast port is enough and you want a compact unit.

• Choose the CM3000 if you want two LAN ports plus link aggregation and a modem built to sit at the center of a wired home network.
• Choose the CM2000 if a single 2.5Gbps port covers your setup and you prefer a smaller, lighter modem.
