- LED Indicators: Monitor the LED lights on the front of the extender to check its status:
- Router LED: Indicates connection status to your main router. Solid green means a good connection.
- Device LED: Indicates connection status to your devices. Solid green means devices are connected.
- Power LED: Indicates the power status of the extender.
- WPS LED: Flashes during WPS setup and turns solid green upon successful connection.
Maintenance
To ensure optimal performance and longevity of your NETGEAR EX3700 Wi-Fi Range Extender, consider the following maintenance tips:
- Firmware Updates: Periodically check the NETGEAR support website for firmware updates. Keeping your firmware up-to-date ensures the best performance, security, and compatibility.
- Optimal Placement: If you notice a decrease in performance, re-evaluate the extender's placement. Ensure it's not too far from the main router and free from obstructions.
- Cleaning: Gently clean the exterior of the extender with a soft, dry cloth. Avoid using liquid cleaners or aerosols.
- Restart: Occasionally restarting the extender (unplugging and replugging after 10 seconds) can resolve minor connectivity issues and improve performance.
Troubleshooting
If you encounter issues with your NETGEAR EX3700, refer to the following common troubleshooting steps:
- No Wi-Fi Connection:
- Ensure the extender is powered on and the Power LED is solid.
- Check the Router LED. If it's not solid green, the extender is not properly connected to your router. Try WPS setup again or move the extender closer to the router.
- If you cannot establish a Wi-Fi connection, connect your computer directly to the extender using an Ethernet cable to access its setup page for manual configuration.
- Poor Signal Strength:
- Relocate the extender to a position that is closer to your main router but still within the desired extended coverage area.
- Minimize physical obstructions (thick walls, large appliances) between the router, extender, and your devices.
- Intermittent Connectivity:
- Restart both your main router and the extender.
- Check for any potential wireless interference from other electronic devices.
- Forgot Password: If you forget the password for the extended network, you can reset the extender to factory settings by pressing and holding the Factory Reset button for about 5-10 seconds. You will then need to set it up again.
