- Log in using the default username and password.
- Navigate to the network settings or 4G/LTE settings to find the APN configuration. Enter the correct APN for your mobile network provider.
5. Operating the Router
5.1. Wi-Fi Connection
Once the router is powered on and has established a 4G LTE connection (indicated by stable signal strength LEDs), you can connect your devices via Wi-Fi:
- On your device (smartphone, laptop, tablet), search for available Wi-Fi networks.
- Select the Wi-Fi network name (SSID) of your STRONG router. The default SSID and password are usually printed on a sticker on the router.
- Enter the Wi-Fi password when prompted.
- Alternatively, use the Connect & Secure (WPS) button for quick Wi-Fi setup with WPS-compatible devices. Press the WPS button on the router, then activate WPS on your device within two minutes.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the router. Do not use liquid cleaners or aerosols.
- Placement: Place the router in a central location, away from obstructions and other electronic devices that may cause interference, to ensure optimal Wi-Fi coverage and 4G signal reception.
- Firmware Updates: Periodically check the manufacturer's website for firmware updates. Keeping your router's firmware up-to-date can improve performance and security.
- Resetting the Device: If the router is not functioning correctly, you can perform a factory reset. With the router powered on, use a paperclip to press and hold the reset button (often combined with the WPS button) for about 10 seconds until the lights flash. This will restore the router to its default settings.
7. Troubleshooting
If you encounter issues with your STRONG 4G LTE Mini Wi-Fi Router, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Power LED Off | Power adapter not connected, power outlet issue. | Ensure power adapter is securely connected to both router and power outlet. Try a different outlet. |
| No 4G LTE Signal / Signal LEDs Off | SIM card not inserted correctly, no active SIM, poor network coverage, incorrect APN settings. | Reinsert SIM card, ensure it's active. Check network coverage in your area. Verify APN settings in the router's web interface. Adjust antenna position or router location. |
| No Internet Access (Wi-Fi or LAN) | No 4G LTE connection, incorrect network settings, device connectivity issue. | Check 4G LTE signal strength. Confirm APN settings are correct. Restart the router and the connected device. Ensure Wi-Fi password is correct. |
| Slow Internet Speed | Weak 4G LTE signal, network congestion, too many connected devices, router placement. | Relocate router for better signal. Limit number of active devices. Check for network congestion with your provider. |
| Cannot Access Router Web Interface | Incorrect IP address, network configuration on computer, router malfunction. | Ensure your computer is set to obtain IP address automatically (DHCP). Verify the router's default IP address. Try a different web browser. Perform a factory reset if necessary. |
