Boost download and upload speeds with your compatible ISP using the CM1200 DOCSIS 3.1 Multi-Gig Cable Modem from Netgear. Equipped with four Gigabit Ethernet ports and a coaxial cable port, the CM1200 cable modem is capable of download speeds up to 10 Gb/s with cable broadband providers that support the DOCSIS 3.1 standard, and it can deliver upload speeds up to 2 Gb/s via link aggregation when used with a compatible router and service plan. Designed to work with XFINITY, Spectrum, and Cox cable broadband internet service, the cable modem boasts IPv6 support and multi-IP address support, ideal for running multiple servers simultaneously.


  • DOCSIS 3.1 Compatible
  • Up to 10 Gb/s Download Speeds
  • 4 x Gigabit Ethernet Ports
  • XFINITY, Spectrum, & Cox Compatibility
  • For Cable Plans Up to 2 Gigabits
  • DOCSIS 3.1 Support

    The DOCSIS 3.1 standard supports up to 10 Gb/s download and 1 Gb/s upload speeds. Since the technology is backwards compatible, upgrading to a DOCSIS 3.1 modem means you can still use your current internet service and be ready when your service provider upgrades to DOCSIS 3.1.

    Works with Your Wi-Fi Router

    Use an Ethernet cable to connect the CM1200 cable modem output port to the WAN port of your existing Wi-Fi router, Wi-Fi system, or directly to your computer.

    Link Aggregation

    Support for link aggregation allows for WAN speeds up to 2 Gb/s with a compatible router and internet service plan.

    Multi-IP Address Support

    The CM1200 supports up to four public IP addresses (WAN IP) with a Comcast Business account, giving you the ability to host multiple servers, such as email, website, or VPN gateway servers. Multi-IP address support also helps to address the challenges of NAT (Network Address Translation) configuration for video conferencing. A Comcast Business service plan is required, and an additional fee may apply.

    ISP Compatibility

    The CM1200 works out of the box with internet cable services such XFINITY from Comcast, Spectrum, and Cox. You can easily self-activate the modem without placing a service call.

    No More Cable Modem Rental Fees

    Eliminate internet service provider equipment rental fees and save up to $156 a year.


    The CM1200 is certified by CableLabs and Comcast.

    System Requirements

    The cable modem requires cable broadband internet service. DOCSIS 3.1 operation requires an ISP that supports the DOCSIS 3.1 standard. The CM1200 is not compatible with cable bundled voice services.
