NETGEAR CM700 Cable Modem – DOCSIS 3.0, Up to 1.4 Gbps, Compatible with Xfinity, Spectrum, Cox

Upgrade your home network with the NETGEAR CM700

The NETGEAR CM700 is a high‑speed cable modem designed to handle demanding online activity. Built on CableLabs DOCSIS 3.0 certification with 32x8 channel bonding, this device emphasizes reliability and smooth performance across multiple devices in a typical home setup.

With downstream speeds listed up to 1.4 Gbps in ideal conditions, real‑world performance varies by service plan, line quality, and network congestion. A single Gigabit Ethernet port provides a fast backbone to a router or direct to a computer, enabling stronger wired performance for your devices while a Wi‑Fi router handles wireless coverage for phones, tablets, and smart home gear.

Setup, requirements, and notes

To get started, connect the CM700 to your coax line, then attach a router via the Ethernet port. It works with most Windows and Mac systems and requires a 12 VDC, 1 A power adapter from NETGEAR. For best results, use a current browser when following the setup guide.

In daily use, the CM700 stays quiet and unobtrusive in a media cabinet or shelf, with a compact form and clear indicators that help you monitor status at a glance. When paired with a reliable router, it becomes a solid backbone for gaming, streaming, and smart home devices—though actual speeds depend on your service plan and network conditions.

Note: CM700 is designed for coax-based cable services and is not compatible with Verizon, AT&T, CenturyLink DSL, or bundled voice services. Always verify compatibility with your specific plan and location before purchase.
