- No Internet Connection:
-
- Check if your SIM card is properly inserted and activated.
- Verify that the WAN cable is securely connected if using a wired internet source.
- Ensure your internet service provider (ISP) is not experiencing outages.
- Perform a power cycle on the router and your modem (if applicable).
- Check the router's web interface for connection status and error messages.
- Slow Wi-Fi Speed:
-
- Ensure your devices are connected to the appropriate Wi-Fi band (5.8GHz for faster speeds, 2.4GHz for wider range).
- Reduce interference by moving the router away from other electronic devices.
- Check for obstacles (walls, large furniture) that might be blocking the signal.
- Update the router's firmware to the latest version.
- Cannot Access Router Web Interface:
-
- Verify your computer is connected to the router via Ethernet or Wi-Fi.
- Ensure you are using the correct IP address (default 192.168.1.1) and login credentials.
