ARRIS Surfboard G54 DOCSIS 3.1 Gateway Modem

The ARRIS Surfboard G54 combines a DOCSIS 3.1 cable modem with a Wi-Fi 7 router in one device. It serves households that want to stop paying monthly rental fees to their cable provider. The gateway supports internet speed plans up to 10 Gbps and works with major U.S. providers. It is built for users who need a single box for both modem and router functions.

Practical limits of DOCSIS 3.1 and Wi-Fi 7

DOCSIS 3.1 enables multi-gigabit speeds over existing coaxial cable, reaching up to 10 Gbps on supported plans. Real-world throughput depends on the provider's network quality and the specific plan purchased. Wi-Fi 7 delivers wireless speeds up to 18 Gbps across quad-band channels. Actual wireless performance varies with home layout, interference and client device capabilities. The gateway includes one 10-Gbps and four 1-Gbps Ethernet ports for wired connections.

Replaces separate modem and router units

This gateway replaces a standalone cable modem plus a separate Wi-Fi router, reducing hardware clutter and eliminating rental fees. The upgrade is worthwhile when your current plan exceeds DOCSIS 3.0 limits or when you need Wi-Fi 7 features for newer client devices. Buyers who want more Ethernet ports than five or who require advanced routing features such as VPN server support should consider separate components. Not for users whose ISP does not support DOCSIS 3.1 or who need modem-only bridge mode for a third-party router.

Questions about this item

Should I choose the G54 for a 10 Gbps cable plan or a slower tier?

The G54 is approved for cable internet speed plans up to 10 Gbps, so it handles the fastest tier and any lower plan from supported providers.

What does the BE 18000 Wi-Fi 7 rating mean for everyday devices?

It indicates a maximum combined wireless throughput of 18 Gbps across the quad-band radio; real-world speeds depend on client capability, interference and distance.

How does the single 10-Gbps Ethernet port limit wired performance?

That port caps a wired link at 10 Gbps, while the four 1-Gbps ports cap at 1 Gbps each; aggregate throughput cannot exceed the port you use.
