Hitron CODA
Score: 71/100Rankings
The Hitron CODA is a DOCSIS 3.1 cable modem supporting up to 1 Gbps plans with dual Gigabit Ethernet ports and MoCA immunity filtering. It lacks integrated Wi-Fi and advanced management, requiring an additional router. Ideal for cable subscribers who need high wired speeds and already have a separate wireless solution.
The Arris SB6121 is a DOCSIS 3.0 cable modem with ENERGY STAR efficiency and front-panel LEDs, delivering up to 172 Mbps downstream for mid-tier broadband. Its limited channel bonding and lack of Wi-Fi make it unsuitable for modern high-speed plans. Ideal for budget-conscious households with basic internet needs.

Professional sources and manufacturer literature praise the SB6121 for its solid 4×4 DOCSIS 3.0 channel bonding, energy-efficient design, and reliable wired performance with major cable providers. However, reviewers note that the modem's DOCSIS 3.0 platform and limited channel count are insufficient for today's high-speed plans, and they recommend upgrading to a DOCSIS 3.1 model for future-proofing.
Typical users find the SB6121 easy to install and reliable for basic internet needs, especially when paired with a separate router for Wi-Fi. Common complaints revolve around its inability to keep up with faster broadband packages, the absence of built-in wireless, and concerns over refurbished units.
Professional reviews are not provided in the source data; however, manufacturers emphasize that the DOCSIS 3.1 technology offers significantly faster speeds and lower latency compared to legacy DOCSIS 3.0 modems, making the CODA suitable for modern high‑bandwidth applications.
No specific consumer reviews were found, but the available information highlights strong interest in the modem's high speeds, dual Gigabit ports, and provider certifications, while users may be disappointed by the lack of built-in Wi-Fi and limited ISP compatibility.
