What Common Both Can Do?

  • DOCSIS Version: Both models use DOCSIS 3.0 technology, which enables high-speed broadband connectivity over cable networks. This standard supports channel bonding to increase bandwidth efficiency and maintain stable performance on compatible ISPs.
  • Backward Compatibility: Each modem supports DOCSIS 2.0 networks, allowing operation in areas where older infrastructure is still deployed. This ensures broader compatibility with legacy cable systems.
  • Gigabit Ethernet Port: Both devices include a single 10/100/1000 Mbps Ethernet port. This allows connection to a separate WiFi router or wired device at full gigabit speeds without internal bottlenecks.
  • Router Built-In: Neither model includes a built-in router. This design allows users to pair the modem with a router of their choice for customized networking performance.
  • WiFi Built-In: Both units function strictly as cable modems without integrated wireless radios. This separation improves flexibility in home network configuration.
  • IPv6 Support: Each modem supports IPv6 networking. This ensures compatibility with modern internet addressing standards and future-proofs the connection.
  • Downstream Modulation: Both models use 64/256 QAM modulation for downstream data transmission. This modulation type improves data efficiency and stability over cable lines.
  • Upstream Modulation: Each modem supports multiple QAM upstream modulation schemes. This allows adaptive performance depending on ISP signal conditions.
  • Ethernet Auto-Negotiation: Both automatically detect and negotiate the best Ethernet speed supported by the connected device. This ensures optimal performance without manual configuration.
  • Auto-Sensing Ethernet: Each modem can automatically detect active network devices when connected. This simplifies installation and reduces configuration steps.
  • LED Status Indicators: Both feature front-panel LED indicators for power, downstream, upstream, internet, and Ethernet activity. These lights provide immediate visual diagnostics for troubleshooting.
  • Vertical Stand Design: Each modem uses a vertical tower form factor. This orientation reduces desktop footprint and improves airflow for passive cooling.
  • ISP Compatibility: Both models are approved for use with major US cable providers. This ensures activation support and standardized provisioning procedures.
  • Plug-and-Play Setup: Each device supports simple activation through ISP registration processes. Users typically connect the coaxial cable and Ethernet cable before completing ISP provisioning online.
  • Coaxial Cable Interface: Both include a single F-type coaxial connector for cable signal input. This is the industry standard for residential cable broadband.
  • Power Adapter Included: Each modem ships with an external power adapter. This provides regulated voltage appropriate for internal circuitry and stable long-term operation.
  • Firmware Updates via ISP: Both models receive firmware updates directly from the internet service provider. This maintains network compatibility and security compliance.
  • Operating Humidity: Each modem is rated for operation within typical residential humidity ranges without condensation. This ensures stable performance in common indoor environments.
