Product details

Fast, future-ready connectivity

Upgrade to the NETGEAR CM1000 and unlock gigabit-class performance for modern households. Built around DOCSIS 3.1, it leverages 32x8 channel bonding and 2x2 OFDM to deliver peak download speeds and smoother streaming, even during peak hours.

Compatibility and real-world use

The CM1000 works with major cable providers and DOCSIS standards. When paired with compatible service plans, you can expect robust performance up to 1 Gbps. Spectrum and Cox-capable networks can reach up to 1 Gbps, while Xfinity plans commonly top out around 800 Mbps. Note that some services or bundled voice features may not be supported. This modem is designed for use in the US.

  • Reliable Ethernet connection: a single Gigabit Ethernet port connects directly to a PC or to a separate router for whole-home Wi‑Fi.
  • Future-ready hardware: DOCSIS 3.1 is compatible with prior 3.0 networks and newer plans as providers upgrade.
  • Rental-fee savings: replacing a rented modem can help you reduce monthly costs over time.

Setup, use, and benefits

Set up quickly by connecting to your router and power. The CM1000 invites you to pair your favorite Wi‑Fi router for broad wireless coverage across multiple devices—phones, laptops, TVs, and gaming consoles—without compromising speed.

  • One Ethernet port provides direct connectivity to a computer or a gateway router.
  • Designed for United States service and policy considerations; verify service compatibility with your provider.

In short, the NETGEAR CM1000 is a capable, future-flexible option for households upgrading to gigabit-capable plans. While speeds vary by plan and network conditions, many users report a noticeable improvement in streaming, gaming, and large file downloads when upgrading from older modems.
