5. Operating Instructions
5.1. Basic Operation
- Power On/Off: Plug in the power adapter to turn on the router. Unplug it to turn off.
- Indicator Lights: Refer to the router's indicator lights for status information (e.g., power, internet connection, Wi-Fi activity).
- Connecting Devices: Connect your devices to the Wi-Fi network using the SSID and password you configured during setup.
5.2. Advanced Features (AiMesh 2.0)
The ASUS XD4 PRO supports AiMesh 2.0, allowing you to create a seamless whole-home Wi-Fi system by combining multiple ASUS AiMesh-compatible routers. This extends your Wi-Fi coverage and eliminates dead zones.
Video 5.1: Overview of ASUS AiMesh Solution, demonstrating how multiple ASUS routers can be integrated to provide whole-home Wi-Fi coverage.
To set up an AiMesh system:
- Ensure all AiMesh-compatible routers are powered on and within range.
- Access the ASUS Router app or web interface of your primary AiMesh router.
- Navigate to the AiMesh section and follow the instructions to add additional AiMesh nodes.
- The system will automatically optimize connections between routers for the best performance.
5.3. Dual-Band Operation
The router operates on both 2.4GHz and 5GHz frequencies. The 2.4GHz band offers wider coverage, while the 5GHz band provides faster speeds for devices closer to the router. You can configure separate SSIDs for each band or use Smart Connect to allow the router to automatically assign devices to the optimal band.
6. Maintenance
- Regular Cleaning: Use a soft, dry cloth to clean the exterior of the router. Do not use liquid cleaners or aerosols.
- Firmware Updates: Regularly check for and install firmware updates through the ASUS Router app or web interface. Firmware updates often include performance improvements, security patches, and new features.
- Restarting the Router: If you experience connectivity issues, try restarting the router by unplugging it from the power outlet for 10 seconds and then plugging it back in.
- Factory Reset: In case of persistent issues or if you forget your login credentials, you can perform a factory reset. Locate the reset button (usually a small pinhole) on the router, press and hold it for about 10 seconds while the router is powered on, then release. This will restore the router to its default factory settings.
7. Troubleshooting
Here are solutions to common issues you might encounter:
- No Internet Connection:
- Check if your modem is working correctly.
- Ensure all cables are securely connected (especially the Ethernet cable from modem to router's WAN port).
- Restart both your modem and router.
- Verify your internet service provider (ISP) settings in the router's web interface.
- Weak Wi-Fi Signal or Dead Zones:
- Relocate the router to a more central position.
- Minimize obstructions between the router and your devices.
- Consider adding another ASUS AiMesh-compatible router to extend coverage.
- Check for interference from other electronic devices.
- Slow Internet Speed:
- Ensure your devices are connected to the 5GHz band if they are close to the router.
- Check for background applications or devices consuming high bandwidth.
- Perform a speed test to confirm if the issue is with your ISP or local network.
- Update router firmware.
- Cannot Access Router Web Interface:
- Ensure your device is connected to the router's network (either Wi-Fi or Ethernet).
- Try different web browsers.
- Verify the router's IP address (default is usually
router.asus.comor192.168.1.1). - Temporarily disable any VPN or firewall software on your computer.
