3. Setup Guide
3.1 SIM Card Installation
- Ensure the router is powered off.
- Locate the SIM card slot on the device. This is typically found under a protective cover on the underside or side of the router.
- Before inserting, ensure your Micro SIM card's PIN code is disabled. This can usually be done using a mobile phone. The router does not support virtual SIMs or IoT SIMs.
- Insert the Micro SIM card into the slot until it clicks into place. Refer to the diagram for correct orientation.
- Close the protective cover securely.

3.2 Antenna Connection
Screw the two external antennas firmly into their designated ports on the router. One antenna is for 4G signal reception, and the other is for WiFi signal transmission. Ensure they are securely attached for optimal performance.
3.3 Power Connection
Connect the provided DC power adapter to the router's DC power input port and then plug it into a standard electrical outlet. The router can also be powered via its Micro USB port using a 12V power bank for outdoor or remote use.
3.4 Initial Access and Configuration
- Power on the router. Wait for the indicator lights to stabilize.
- Connect your computer or mobile device to the router's WiFi network. The default WiFi name (SSID) and password are usually printed on a label on the router itself. Alternatively, connect your computer to the router via an Ethernet cable.
- Open a web browser and enter the default IP address for the router's web interface. This is typically 192.168.199.1. The default login password is often admin.
- Once logged in, navigate to the Network Settings section, then select APN.
- Configure the correct APN settings for your SIM card's mobile operator. If you are unsure of the APN details, contact your service provider. Save the settings and restart the router for changes to take effect.

5. Maintenance
5.1 Cleaning
To maintain optimal performance, periodically clean the exterior of the router with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials.
5.2 Environmental Considerations
While the router unit itself has an IP66 waterproof rating, the power adapter is not designed for outdoor exposure. Ensure the power adapter is protected from rain, snow, and direct sunlight. For outdoor installations, consider using a weather-resistant enclosure for the power supply or a power source specifically designed for outdoor use.

6. Troubleshooting
6.1 No Internet Connection
- Check SIM Card: Ensure the SIM card is active, has data, and its PIN code is disabled.
- APN Settings: Verify that the APN settings in the router's web interface are correct for your mobile operator.
- Signal Strength: Check the signal indicator LEDs. If the signal is weak, try repositioning the router or adjusting antenna orientation.
- Network Coverage: In rural areas, signal coverage can be inconsistent. Ensure you are within a service area.
6.2 Slow Speeds or Frequent Disconnections
- Signal Strength: A weak 4G signal will result in slower speeds. Optimize router placement.
- Network Congestion: Performance can be affected by network traffic from your service provider.
- Device Limit: The router supports up to 10 devices. Exceeding this limit may degrade performance.
- Reboot: Sometimes, a simple reboot of the router can resolve connectivity issues.
6.3 Resetting the Device
If you encounter persistent issues, you can perform a factory reset. Locate the 'RESET' button (often a small pinhole) on the router. Use a paperclip or similar pointed object to press and hold the button for approximately 5-10 seconds until the indicator lights flash. This will restore the router to its default factory settings, including WiFi name, password, and login credentials.
