Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Cable Modem | 2.5 GbE

The Hitron CODA56 is a multi-gigabit DOCSIS 3.1 cable modem with a single 2.5 Gigabit Ethernet port, built for cable plans from gigabit up to 2.5 Gbps. It is certified by Comcast Xfinity, Charter Spectrum, Cox, and Mediacom, and it is one of the few retail modems on Xfinity's Next Gen Speed Tier list, which means it supports the faster mid-split upload speeds Xfinity is rolling out. Pair it with any WiFi router or mesh system you already own and stop paying the monthly gateway rental fee.

Who the CODA56 is for

• Gigabit and multi-gig cable plans (1 Gbps to 2.5 Gbps) where a standard 1 GbE port would cap wired speeds near 940 Mbps
• Xfinity customers on plans that advertise enhanced uploads, since the CODA56 is approved for Next Gen upload tiers
• Households that game, stream 4K, run video calls, and juggle a house full of smart devices at the same time
• Anyone who wants a standalone modem to pair with their own router or mesh WiFi system

Key features

• DOCSIS 3.1 with 2x2 OFDM/OFDMA channels, backward compatible with DOCSIS 3.0 (32x8 channel bonding)
• One 2.5 GbE port so your router receives the full speed of a gigabit or multi-gig plan
• Mid-split upload support for Xfinity Next Gen tiers where the network upgrade has reached your area
• Broadcom chipset for stable, low-latency performance
• IPv4 and IPv6 support
• Modem only, no built-in WiFi. Works with any router or mesh system (sold separately)

Specifications

Provider compatibility

The CODA56 is on the approved lists for Comcast Xfinity, Charter Spectrum, Cox (including Gigablast), and Mediacom, plus Sparklight and several regional cable providers. A few plan-specific notes:

• Xfinity: Listed as Recommended and on the Next Gen Speed Tier table. If your plan advertises uploads in the hundreds of megabits, this is one of the modems that can actually deliver them. See our Xfinity approved modem list.
• Spectrum: Authorized for plans up to 1 Gig. Spectrum's 2 Gig plan still requires Spectrum's own gateway. See our Spectrum approved modem list.
• Cox: Certified for all tiers including Gigablast. Cox supplies its own hardware if you bundle voice service.

Provider lists change a few times a year. Confirm your plan and speed tier against your ISP's current list before you order.

Why the 2.5 GbE port matters

Cable providers over-provision gigabit plans, so a modem with a standard 1 GbE port tops out around 940 Mbps in practice. The CODA56's 2.5 GbE port removes that ceiling. To see the benefit, connect it to a router with a 2.5 GbE WAN port. Most WiFi 6E and WiFi 7 routers have one, and so do most current mesh systems. If your router only has a 1 GbE WAN port, the CODA56 still works, but you will not see speeds above gigabit until you upgrade the router too. Browse our gigabit-ready routers and mesh WiFi systems.

Common questions

Does the Hitron CODA56 have WiFi?

No. It is a standalone cable modem. You connect it to your own WiFi router or mesh system with an Ethernet cable.

Is the CODA56 approved for Xfinity's faster upload speeds?

Yes. It appears on Xfinity's Next Gen Speed Tier list, which is the list Xfinity uses for mid-split upload tiers. Actual upload speed depends on whether the mid-split upgrade has reached your neighborhood and on your plan.

Does it work with Spectrum's 2 Gig plan?

No. Spectrum authorizes retail modems on plans up to 1 Gig only. The 2 Gig plan requires Spectrum-provided equipment.

Will it work with fiber or DSL internet?

No. The CODA56 is a DOCSIS cable modem and only works with cable internet providers. Fiber services like AT&T Fiber and Verizon Fios use an ONT, not a modem.

How do I activate it?

Connect the coax cable and power, then call your provider or use their app to register the modem's MAC address (printed on the label). Xfinity customers can self-activate through the Xfinity app. Most activations take 10 to 15 minutes.
