NETGEAR Nighthawk CM1200 FAQ

  1. Does the NETGEAR Nighthawk CM1200 have a built-in router?

    No, this modem is not a router combo. You can, however, use it with a WiFi router of choice but it should be a wireless AX router for optimal performance.

  2. Why does the CM1200 have 4 ethernet ports?

    These ports are for future Internet upgrades to support speeds above 1 Gbps. This accomplished with link port aggregation. These Ethernet ports are not for routing capabilities. Only one port can be used for a single wired device, whether it be a PC, TV, or even a separate router.
