Overview
The ARRIS Surfboard G54 is a combined DOCSIS 3.1 cable modem and Wi-Fi 7 router, covering 2.4, 5, and 6 GHz bands. It has 4 Ethernet ports with a max wired speed of 2.5 Gbps per port.
Who it suits
Suited to US households on cable broadband who want a single device handling both modem and Wi-Fi 7 routing. It fits setups needing multiple wired connections rather than a mesh or whole-home wireless expansion plan.
Reasons to consider it
It supports Wi-Fi 7 across all three bands including 6 GHz, which can help with newer client devices. The built-in DOCSIS 3.1 modem removes the need for a separate modem box, and 4 Ethernet ports at up to 2.5 Gbps give flexibility for wired gear.
Limitations and compatibility checks
It works only with US cable providers and is not compatible with fibre connections or bundled voice service. There is no wired backhaul support, no USB or PoE ports, and no listed ecosystem for mesh expansion.
