Manufacturer description

The Hitron CODA56 is a bare-bones DOCSIS 3.1 cable modem built for one job: replacing your ISP's rental box on a multi-gig coaxial plan. Its single 2.5 Gbps Ethernet port supports plans up to 2.5 Gbps, with certified compatibility on Xfinity (up to 2.33 Gbps), Spectrum (1 Gbps), and Cox (2 Gbps). DOCSIS 3.1 channel bonding keeps latency low for 4K streaming, competitive gaming, and video calls, and the modem stays backward compatible with DOCSIS 3.0 networks if your area has not upgraded yet. Read the name carefully before you buy. This is a modem only: no WiFi radio, no phone or voice…

SpecPicks Verdict

SpecPicks scored Hitron CODA56 DOCSIS 3.1 Cable Modem ONLY with 3-Year Warranty using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. Hitron's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Does the Hitron CODA56 have built-in WiFi?

No. The CODA56 is a modem only, with no WiFi radio and no router features. You need a separate WiFi router, ideally one with a 2.5 Gbps port, to reach full plan speeds across multiple devices.

Will this modem work with my fiber internet?

No. The CODA56 works only with internet delivered over coaxial cable, the round cable with a screw-on connector. It will not work with Verizon FiOS, AT&T Fiber, Google Fiber, DSL, satellite, or 5G home internet, even if your provider is Xfinity, Spectrum, or Cox.

What internet speeds does the CODA56 support?

It supports plans up to 2.5 Gbps through its 2.5 Gbps Ethernet port. Certified provider speeds are up to 2.33 Gbps on Xfinity, 2 Gbps on Cox, and 1 Gbps on Spectrum. It is designed for plans of 1 Gbps and faster.

What warranty comes with the Hitron CODA56?

Hitron includes 3 years of total coverage: a standard 1-year warranty plus a 2-year extended warranty. Hitron also provides technical support 7 days a week and product registration.

What do I need to set it up?

Three things: active cable internet service that is not fiber, a separate WiFi router with a 2.5 Gbps port for full speeds, and an activation call to your ISP. Without a router you can connect only one device using the included Ethernet cable.
