The NETGEAR C7000 is the DOCSIS 3.0 modem-router combo in this selection, while the ARRIS G34 and NETGEAR CAX30 offer DOCSIS 3.1 with Wi-Fi 6. Choose a combo for one-device setup, or a modem-only model if you already have a router. The Hitron CODA56 and NETGEAR CM500 do not include Wi-Fi, so they are not standalone matches for shoppers seeking a cable modem with built-in Wi-Fi.
| Product | Wi-Fi included | Best fit |

| ARRIS Surfboard G34 | Yes, Wi-Fi 6 | Plans up to 1 Gbps |
| NETGEAR Nighthawk CAX30 | Yes, Wi-Fi 6 | Supported cable plans up to 1 Gbps |
| NETGEAR Nighthawk C7000 | Yes, Wi-Fi 5 | DOCSIS 3.0 plans up to 800 Mbps |

ARRIS Surfboard G34 DOCSIS 3.1 Wi-Fi 6 Combo
Best for: Cable customers who want a single modem-router device and a plan advertised up to 1 Gbps. The listed specifications identify a DOCSIS 3.1 modem, AX3000 Wi-Fi 6, coverage up to 2,500 square feet, and four 1 GbE ports.
It is listed as compatible with Xfinity, Cox, and Spectrum. The G34 is a suitable choice for buyers who prioritize a newer modem standard and Wi-Fi 6 rather than specifically requiring DOCSIS 3.0. Its key limitation is that the listed wired ports are 1 GbE, and actual internet performance depends on the plan and provider.
NETGEAR Nighthawk CAX30 Wi-Fi 6 Combo
Best for: Buyers seeking a DOCSIS 3.1 modem and Wi-Fi 6 router in one device. The product information lists compatibility with Xfinity plans up to 800 Mbps, Spectrum up to 1 Gbps, and Cox up to 1 Gbps. It also describes AX2700 wireless and multi-gig DOCSIS 3.1 capability.
Choose this combo if your provider and plan appear on its supported list and you want to avoid a separate modem and router. Provider activation is required. It is not compatible with several non-cable services, including Verizon, AT&T, and CenturyLink, or bundled voice plans, so verify your service before buying.
NETGEAR Nighthawk C7000 DOCSIS 3.0 Combo
Best for: Shoppers who specifically want DOCSIS 3.0 with built-in Wi-Fi and have a cable plan within the stated speed range. This renewed model combines a DOCSIS 3.0 modem with AC1900 Wi-Fi 5 and is listed for cable plans up to 800 Mbps.
The product information lists compatibility with providers including Xfinity and Cox, but excludes Spectrum, bundled voice services, and several non-cable providers. Because it is renewed, check the listing details and your provider’s current device requirements. Choose a DOCSIS 3.1 model instead if your plan or ISP requires that standard.
Hitron CODA56 DOCSIS 3.1 Modem Only
Best for: Buyers who already own a router or want to select a separate Wi-Fi system. The listed product is a DOCSIS 3.1 modem with a stated speed capability of up to 2.5 Gbps and compatibility with Xfinity, Spectrum, and Cox.
This is not a modem-router combo: the product description explicitly says it has no Wi-Fi and requires a router. It is also not intended for fiber or DSL service. Choose it only if you are comfortable setting up a separate router and have confirmed the modem is supported for your exact plan.
NETGEAR CM500 DOCSIS 3.0 Modem
Best for: Cable customers with plans up to 400 Mbps who already have a Wi-Fi router. The product name identifies a DOCSIS 3.0 modem compatible with major cable providers, including Xfinity and Cox.
The CM500 is a modem, not a modem-router combo, so it does not provide Wi-Fi by itself. That makes it a less direct choice for shoppers who want one device. Confirm your ISP supports this model and your speed tier before purchase, particularly if you may move to a faster plan.
Buying Guide: How to Choose a Cable Modem With Wi-Fi
Do you need DOCSIS 3.0 or DOCSIS 3.1?
Match the modem standard to your cable provider’s requirements and your plan. The C7000 and CM500 are DOCSIS 3.0 models; the G34, CAX30, and CODA56 are DOCSIS 3.1. A newer standard does not guarantee a particular speed: your plan, provider network, and device approval also matter.
Should you get a combo or separate devices?
A modem-router combo combines internet access and Wi-Fi in one unit, which can simplify equipment setup. A modem-only device requires a separate router, but lets you choose or replace Wi-Fi equipment independently. The CODA56 and CM500 are modem-only options in this selection.
How do you check provider compatibility?
Check the ISP’s approved-device list for the exact model and your service tier. Compatibility can vary by provider, plan, and bundled services. Also confirm whether the device supports your service type: these listed products are cable modems, not fiber or DSL modems.
What Wi-Fi details matter?
Wi-Fi 6 appears on the G34 and CAX30; the C7000 lists Wi-Fi 5. Compare the stated wireless generation and any coverage information with your household’s needs, but do not treat a manufacturer’s coverage estimate as guaranteed performance in every home. Walls, layout, and device placement can affect coverage.
