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 certified of download speeds up to 1 Gb/s with cable broadband providers that support the DOCSIS 3.1 standard. Combining two of the four Gigabit Ethernet LAN ports using link aggregation allows to take advantage of 2 Gb/s services with compatible devices. 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.
ISP Compatibility
The CM1200 is certified with Xfinity speeds of up to 800 Mb/s. It supports Spectrum and Cox services of up to 1 Gb/s. You can easily self-activate the modem without placing a service call.
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
Combine the first two Gigabit Ethernet LAN ports to transfer up to 2 Gb/s with compatible devices.
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.
