Question

How do I set my G18/G20 in a router mode?

Answer

The G18/G20 operates as a DOCSIS Wi-Fi cable modem and provides Internet access through a coaxial connection. Setting the G18/G20 in Router mode disables the modem functions and will operate as a Wi-Fi router. A modem with an Internet connection will need to be connected to the Ethernet port 1 on the G18/G20. This document describes how to set up the G18/G20 in router mode using the Web Manager.

Requirements

Internet service
Ethernet cable
Cable or DSL Modem, or Fiber ONT
