ARRIS SURFboard G54

It is a broadband gateway that combines cable-modem and home-network functions in one device. It uses DOCSIS 3.1 for the cable connection and provides networking for multiple devices.

The catalog description lists speeds up to 1.2 Gbps. The usable speed still depends on the cable provider, subscribed plan, network conditions, and whether the provider supports the device.

Yes. The SURFboard G54 is a DOCSIS 3.1 cable gateway, a standard designed for high-speed broadband service and improved capacity over older DOCSIS generations.

It is intended to serve multiple devices in a home network, including computers, phones, televisions, and game consoles. The practical limit depends on the Wi-Fi environment and the traffic generated by those devices.
