[Mobile Router] How to Enable Dual-WAN Mode on ASUS 5G-GO?

The ASUS 5G-GO supports internet access via Cellular, Ethernet WAN, and WiFi WAN, with flexible combinations.

You can enable and configure Dual-WAN via two methods:

 

Method 1: Set Up Dual-WAN via Web QIS (Quick Internet Setup)Recommended for most users who prefer guided configuration.

QIS provides a guided setup process for easy Dual-WAN configuration.

   1. Connect your device to the ASUS 5G-GO via WiFi or Ethernet

   2. Open a browser and go to: http://192.168.10.1

   3. Click on QIS on the homepage

   4. Follow the on-screen instructions to:

  • Select your desired Dual-WAN Mode (e.g., Cellular + Ethernet WAN)
  • Configure necessary WAN settings (e.g., Static IP, PPPoE, WiFi credentials)
  • Complete the setup and apply changes

 

Method 2: Manually Configure Dual-WAN via LCD + Web Interface

Use this method if you prefer manual control or need to adjust advanced WAN settings.

Routing & Load Balancing Behavior

  • Default behavior: WiFi WAN and Cellular WAN are automatically configured in load-balancing mode

Make sure the WiFi WAN interface is assigned to the wan firewall zone and uses DHCP client protocol unless otherwise required.
