What Common Both Can Do?

  • DOCSIS Standard: Both modems use DOCSIS 3.0 technology, which enables high-speed broadband over cable networks. This ensures compatibility with most modern cable ISP infrastructures and supports reliable data transmission.
  • Backward Compatibility: Each model supports DOCSIS 2.0 backward compatibility. This allows them to function with older cable systems if necessary, ensuring flexibility during ISP transitions.
  • Gigabit Ethernet Port: Both devices include a single 10/100/1000 Mbps Ethernet port. This allows direct connection to a router or computer with support for gigabit wired speeds.
  • Ethernet Port Type: Each modem uses a standard RJ-45 Ethernet connector. This ensures universal compatibility with common Ethernet cables and networking equipment.
  • IPv6 Support: Both modems support IPv6 addressing. This is important for long-term internet scalability and compatibility with modern network configurations.
  • ISP Compatibility: Each modem is designed for use with major U.S. cable internet providers. This broad compatibility simplifies activation and deployment across different service areas.
  • Cable Interface: Both units connect to the internet using a coaxial cable with an F-type connector. This is the standard physical interface for cable broadband connections.
  • LED Status Indicators: Both modems feature LED lights for Power, Downstream, Upstream, Internet, and Ethernet activity. These indicators help users quickly diagnose connection status and troubleshoot issues.
  • External Power Adapter: Each modem uses an external power supply. This keeps internal heat lower and allows easier replacement if the adapter fails.
  • Standalone Cable Modem: Both devices function strictly as cable modems. They are intended to be paired with a separate WiFi router for wireless networking.
  • No Built-in WiFi: Neither model includes integrated wireless functionality. This allows users to choose their own preferred router for customized network performance.
  • No Built-in Router: Both lack NAT routing capabilities. This ensures they operate purely as modems without overlapping router features.
  • Auto-Sensing Ethernet: Each modem automatically detects the speed of the connected Ethernet device. This ensures stable communication without manual configuration.
  • Plug-and-Play Setup: Both models support simple ISP activation procedures. Users can connect the modem, contact their ISP, and complete activation without complex configuration steps.
  • Vertical Stand Design: Each modem uses a vertical orientation for placement. This design minimizes desk footprint and promotes airflow.
  • Vented Cooling Chassis: Both feature vented enclosures to dissipate internal heat. Proper ventilation helps maintain consistent performance during continuous operation.
  • Retail Packaging Type: Each device is sold as a consumer retail cable modem. This allows customers to purchase and activate them independently rather than renting from an ISP.
