3.2 Web Browser Setup
- Plug the Wi-Fi Extender into an electrical outlet.
- On your mobile device or computer, connect to the extender's default Wi-Fi network (e.g., "WiFi 2.4G pro_XXXXXX" or similar, usually found on a label on the device or packaging). This network will typically be unsecured.
- Open a web browser and enter the default IP address (e.g., 192.168.10.1) or domain name (check the user manual included in the box for the exact address).
- Follow the on-screen instructions to log in (default username/password is often 'admin'/'admin' or similar).
- Select "Repeater Mode" and choose your existing Wi-Fi network from the list.
- Enter the password for your existing Wi-Fi network.
- Configure the extended network's name (SSID) and password. You can choose to keep the same name with an "_EXT" suffix or create a new one.
- Save the settings and wait for the extender to reboot.
- Once rebooted, connect your devices to the new extended Wi-Fi network.

4. Operating Modes
The NEWFAST NF-RE516 supports three distinct operating modes to suit various networking needs:
- Repeater Mode: Extends the coverage of an existing wireless network. This is ideal for eliminating Wi-Fi dead zones in larger homes or offices.
- AP (Access Point) Mode: Transforms a wired internet connection into a wireless access point. This is useful for adding Wi-Fi capability to a wired-only network.
- Router Mode: Functions as a standalone router, turning a wired signal from a modem into a private wireless network.

5. Network Security
The NEWFAST NF-RE516 supports WPA/WPA2 security protocols to protect your home network and connected devices from unauthorized access and cyber threats. Ensure your main router and extender are configured with strong, unique passwords and the latest security standards.

6. Troubleshooting
- No Power: Ensure the extender is securely plugged into a working electrical outlet. Check if the Power LED is illuminated.
- Weak Signal: If the Signal Strength LEDs indicate a weak connection, try repositioning the extender closer to your main router. Obstacles like thick walls can reduce signal strength. Adjust the rotatable antennas for optimal reception.
- Cannot Access Setup Page: Ensure your device is connected to the extender's default Wi-Fi network. Try clearing your browser's cache or using a different browser. Verify the IP address or domain name.
- No Internet Access After Setup: Confirm that the extender is successfully connected to your main router (solid Signal Strength LEDs). Check your main router's internet connection. Ensure you entered the correct Wi-Fi password for your main router during setup.
- Factory Reset: If you encounter persistent issues, you can perform a factory reset by pressing and holding the WPS/Reset button for approximately 8-10 seconds until all LEDs flash. This will revert the extender to its default settings, requiring re-configuration.
