DOCSIS 3.1 Cable Modem with AX3000 Wi-Fi

The ARRIS Surfboard G36-RB combines a DOCSIS 3.1 cable modem and a Wi-Fi 6 router in one unit. It supports cable internet plans up to 2.5 Gbps and works with major U.S. providers such as Cox, Spectrum and Xfinity. Setup and management are handled through the SURFboard Central App.

Suits homes needing modem and router together

This device fits households that want a single box for cable modem and wireless routing duties. It is not for buyers who need a separate modem only, nor for installations that require fibre or DSL connectivity. Builders needing more than five wired Ethernet ports should look at something else.

2.5 Gbps Ethernet port for multi-gig plans

The single 2.5 Gbps port is the specification that determines whether the G36-RB matches your service tier. If your cable plan exceeds 2.5 Gbps or you require additional multi-gig ports, this unit will not meet that requirement.

Questions about this item

What does the AX3000 rating mean for actual wireless speed in my home?

AX3000 is the combined theoretical maximum across both Wi-Fi 6 bands; real-world throughput will be lower and depends on device capability, distance and interference.

How does the DOCSIS 3.1 interface limit the maximum internet plan speed I can use?

The modem supports DOCSIS 3.1 with 2 downstream and 2 upstream OFDM channels, enabling cable plans up to 2.5 Gbps.

What physical connections does the G36 need for power and wired devices?

It requires a coaxial cable for the cable line, a power adapter, and provides one 2.5 Gbps Ethernet port plus four 1 Gbps Ethernet ports for wired clients.
