Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Internet Connection | SIM card not activated or improperly inserted; no cellular signal; incorrect APN settings. | Verify SIM card activation and insertion. Check cellular signal strength. Configure APN settings via the web interface according to your carrier's specifications. Restart the router. |
| Slow Internet Speed | Weak cellular signal; network congestion; outdated firmware. | Relocate the router to an area with better signal. Check for and install firmware updates. Consider using Band Lock to optimize signal. |
| Cannot Access Web Interface | Incorrect IP address; network connectivity issue; forgotten password. | Ensure your device is connected to the router's network. Verify the router's IP address. Try a different browser. If password is forgotten, perform a factory reset (note: this will erase all custom settings). |
| Wi-Fi Signal Issues | Interference; router placement; antenna orientation. | Place the router in a central location, away from obstructions and interference sources. Adjust Wi-Fi antenna orientation. Utilize Wireless Repeater Mode if needed. |
