NETGEAR Nighthawk CM3000 DOCSIS 3.1 Modem — 2.5Gbps Down, 1Gbps Up, Works with Xfinity, Spectrum, Cox

Unlock Ultra-Fast Cable Internet with DOCSIS 3.1 Mid/High-Split Technology

The NETGEAR Nighthawk CM3000 is a DOCSIS 3.1 mid/high-split modem designed to meet today’s high-speed plans. Built to handle the fastest cable internet offered by major providers, it pairs with your existing router to deliver impressive download and upload capabilities. Expect smoother streaming, quicker app updates, and more responsive online activities as homes lean into multi-gig plans and high-bandwidth usage.

With support for up to 2.5 Gbps downstream and 1 Gbps upstream, the CM3000 is purposefully engineered for networks that leverage mid/high-split technology. While speeds vary by provider and plan, this modem is designed to keep pace with expanding requirements and evolving services, especially when paired with a modern NETGEAR router or Orbi system.

In real-world use, the CM3000 shines when households juggle several devices: gaming consoles, laptops, smartphones, smart TVs, and home security gear. A direct connection from the modem to a multi-gig router via the 2.5 Gigabit Ethernet port provides a capable backbone for high-speed networking, while existing WiFi coverage handles daily tasks across rooms and floors. You can also rely on easy remote access to home cameras and NAS storage, thanks to robust upstream performance and stable speeds across devices.
