NETGEAR Nighthawk CM1000 Cable Modem vs NETGEAR Nighthawk CM3000 Cable Modem

Buy the CM3000 if your cable plan is 1 Gbps or faster, or if you expect to move to a multi-gig tier. It has a 2.5 Gbps port, a second Gigabit port with link aggregation, and mid/high-split support for uploads up to 1 Gbps. The CM1000 tops out at 1 Gbps on a single Gigabit port and is a solid, proven pick for 800 Mbps to 1 Gbps plans. Both are standalone modems with no WiFi, both carry a one-year warranty, and owners of both report stable connections. The CM3000 rates higher but on far fewer ratings.

• Choose the CM1000 if your plan is 1 Gbps or slower and you want the long-track-record modem that thousands of owners have run without trouble.
• Choose the CM3000 if you have or plan to get a multi-gig cable tier, want faster uploads, or need more than one LAN port.
