User Manual for Xiaomi Mi Router 4A Gigabit Edition

Quick guide from the manual

To set up your Xiaomi Mi Router 4A Gigabit Edition, connect the power and the Internet (WAN) cable from your modem to the router. Once powered on, connect to the default Wi-Fi network using a phone or computer, then follow the on-screen instructions at router.miwifi.com to configure your network settings.

Hardware connection

1. Connect the power adapter to the router.

2. Connect the Internet (WAN) port on the router to your DSL, Cable, or satellite modem using an Ethernet cable.

3. If your internet connection comes directly from a wall Ethernet port, connect that cable directly to the Internet (WAN) port on the router.

Network configuration

1. Connect to the Wi-Fi network (no password required) using a phone or computer. The Wi-Fi name is located on the base of the router.

2. Wait for the system indicator light to turn blue.

3. Open a web browser and navigate to router.miwifi.com or 192.168.31.1. If you are not automatically redirected, enter the address manually.

4. Follow the on-screen prompts to enter your broadband account name and password provided by your service provider.

5. Set a new Wi-Fi name and administrator password. You may choose to use the Wi-Fi password as the administrator password.

Managing the router

You can manage your router anytime using the Mi WiFi app. Scan the QR code provided in the manual to download the app. The web management interface at router.miwifi.com also supports basic internet functions, QoS, unauthorized access prevention, and Wi-Fi optimization.

Indicator lights

The router features two indicator lights on the front panel:

• Network status light (Blue): Off means nothing is plugged into the WAN port or there is a connection issue. On means the connection is normal. Flashing means data is being sent or received.
• System status light (Blue, Orange, Purple): Off means the device is off. Orange means the system is updating or booting. Blue means functioning normally. Purple means safe mode or system failure.

Troubleshooting

If you cannot connect to the internet, ensure the router is powered on and fully booted. Connect to the router's Wi-Fi and visit router.miwifi.com to run network diagnostics. If you have forgotten your administrator password, try using your Wi-Fi password. If that fails, perform a factory reset.

Factory reset

To restore factory settings, ensure the router is booted, then hold down the Reset button at the base for more than 5 seconds. Release the button when the system status light turns orange. The router will reboot with factory settings.
