What customers say
Customers overwhelmingly value the NETGEAR CM1000 for its exceptional speed and reliability, especially for gigabit internet plans. Users report significant stability and faster downloads compared to older models, making it ideal for heavy streaming and gaming.

Know before you buy
No, the CM1000 is a dedicated cable modem and does not provide Wi-Fi. You will need to connect a separate wireless router to the Ethernet port to create a Wi-Fi network for your home.
The CM1000 is compatible with most major U.S. cable internet providers, such as Xfinity, Cox, and Spectrum. However, you should always check your provider's 'approved modems' list on their official website before purchasing to ensure it is certified for your specific service tier.
DOCSIS 3.1 is the latest standard for cable internet, allowing for significantly faster download and upload speeds compared to older DOCSIS 3.0 devices. It also improves network efficiency, which helps reduce lag during high-bandwidth activities like gaming or 4K streaming.
The CM1000 features a single 1-Gigabit Ethernet port, which limits the maximum wired speed to 1 Gbps. If your internet plan offers speeds higher than 1 Gbps, you would need a modem with a 2.5 Gbps or higher Ethernet port to fully utilize that bandwidth.
Yes, the CM1000 is backward compatible with DOCSIS 3.0 networks. This means it will function on older systems while still providing the performance benefits of its 32x8 channel bonding.
