NETGEAR Nighthawk CM1200 FAQ

Is the NETGEAR CM1200 a Modem & Router?

No. The Ethernet ports on the back of the CM1200 are for Link Aggregation / Port Forwarding support. Link Aggregation is a new technology that readies today’s devices for future network speed upgrades. This is accomplished by combining two separate IP addresses and two separate Ethernet ports.
