  • CODA56 black

    Model: CODA56

    What differs
    Black finish of the CODA56, also with one 2.5 Gbps Ethernet port.
    Best for
    Buyers who prefer a black modem.

  • CODA gigabit model

    Model: CODA

    What differs
    A different modem model with gigabit Ethernet rather than the CODA56’s 2.5 Gbps port. It also needs a separate Wi-Fi router.
    Best for
    Cable connections that only need gigabit Ethernet.

Watch out

  • Check the full model name: CODA and CODA56 are different modems.
  • White and black are finish choices; neither adds Wi-Fi.
  • A duplicate CODA56 listing is not proof of a newer hardware version.
  • Confirm whether the offer is modem-only or a bundle, and check the supplied warranty terms.

Why people pick it

  • 2.5 Gbps port for multi-gig cable plans
  • Switchable 5-85 MHz upstream for mid-split plans (datasheet)
  • Maker lists approvals for Xfinity, Spectrum and Cox

Know before you buy

  • Only one Ethernet port
  • No voice (phone) support
  • No Wi-Fi: needs a separate router
