Editor Pick – Hitron CODA56 2.5Gbps Cable Modem
If you want a cable modem with multiple Ethernet ports, this Hitron CODA56 is not the right fit because it includes just one Ethernet port.

Best Multi-Port Option – ARRIS SURFboard S33 Multi-Gig Modem
If your search is focused on a cable modem with multiple Ethernet ports, the ARRIS SURFboard S33 is the clearest match here. It includes a 2.5 Gigabit Ethernet port plus a 1 Gigabit Ethernet port, giving you more flexibility for a high-speed router, wired device, or provider-specific handoff.

This Hitron CODA56 is another modem-only cable internet option for people who want fast DOCSIS 3.1 service and do not need built-in WiFi. It supports plans up to 2.5 Gbps, but it has only one Ethernet port, so it is not a cable modem with multiple Ethernet ports.

Pros:
- DOCSIS 3.1 support for cable plans up to 2.5 Gbps
- 2.5 Gbps Ethernet port for multi-gig service

How We Picked the Best Cable Modem with Multiple Ethernet Ports
We focused on cable modems with multiple Ethernet ports or multi-gig Ethernet options, plus support for current DOCSIS standards, strong ISP compatibility, and speed tiers that match real-world cable plans. We also prioritized models that are practical for buyers who want fewer bottlenecks and a simpler network layout.
Quick Comparison
For most buyers, the main decision is whether you need extra LAN flexibility, multi-gig throughput, or just a dependable modem that pairs with a separate router. A Cable Modem with Multiple Ethernet Ports is most useful when you want to connect a router, switch, or another wired device without immediately upgrading the rest of your network.
Key Buying Factors for a Cable Modem with Multiple Ethernet Ports
Ethernet Port Count and Speed
More ports can help with flexible wiring, but speed matters just as much. Some modems offer multiple 1G ports, while others use one 2.5GbE port for higher aggregate performance. If your plan is above 1 Gbps, look for multi-gig support so the modem is not the limiting factor.
DOCSIS Version
DOCSIS 3.1 is the safer choice for modern cable plans and better future-proofing. DOCSIS 3.0 can still work well for lower-speed plans, but it is less suitable if you expect upgrades or want the best long-term value.
ISP Certification
Always verify compatibility with your provider before buying. Even a strong modem can be a poor fit if it is not approved for your service area or plan tier.
Router Needs
Most cable modems are modem-only devices, so you will still need a separate router for Wi-Fi and advanced home networking. If you want to feed a mesh system or a high-end router, choose a modem with an Ethernet setup that matches your network goals.
Who Should Buy Which Cable Modem with Multiple Ethernet Ports?
If you have a standard cable plan and want the simplest upgrade, a proven DOCSIS 3.0 or entry-level DOCSIS 3.1 model can be enough. If you have gigabit or multi-gig service, choose a model with 2.5GbE or other multi-gig Ethernet support. If you are building a wired home office, gaming setup, or multi-device network, a Cable Modem with Multiple Ethernet Ports gives you more flexibility for direct connections and cleaner expansion.
