5. Troubleshooting

This section addresses common issues you might encounter with your Huawei H155-381 5G CPE 5 Router.

5.1 No Internet Connection

• Check SIM Card: Ensure the Nano-SIM card is correctly inserted and active.
• Network Signal: Verify the 5G/4G LED indicators. If they are off or red, there might be no signal or a network issue. Try relocating the router to an area with better signal reception.
• Power: Ensure the router is properly powered on and the power adapter is securely connected.
• Data Plan: Confirm your mobile data plan is active and has available data.

5.2 Weak Wi-Fi Signal or Slow Speeds
