Method 2: Web Browser Setup
- Plug the AERVY WiFi Extender into a power outlet.
- Connect your computer or mobile device to the extender's default Wi-Fi network (e.g., "AERVY_Extender"). No password is required initially.
- Open a web browser and enter the default IP address or domain name (refer to the Quick Installation Guide for specific details, usually
192.168.1.1oraervy.extender). - Follow the on-screen instructions to select your existing Wi-Fi network and enter its password.
- Configure the extender's network name (SSID) and password if desired.
- Complete the setup process. The extender will restart.
- Once restarted, unplug the extender and move it to an optimal location. Connect your devices to the new extended Wi-Fi network.
Operating the WiFi Extender
Once successfully set up, the AERVY WiFi Extender operates automatically. It will broadcast an extended Wi-Fi signal, allowing your devices to connect to it for improved coverage.
Indicator Lights
- Power Indicator: Illuminates when the device is powered on.
- Wi-Fi Indicator: Shows the status of the Wi-Fi signal. A solid light typically means a stable connection.
- WPS Indicator: Flashes during WPS pairing, and becomes solid when successfully connected via WPS.
- Ethernet Indicator: Lights up when an Ethernet cable is connected and an active network link is established.
Ethernet Port Usage
The integrated Ethernet port allows you to connect a wired device (such as a desktop computer, gaming console, or smart TV) directly to the extender. This provides a stable, high-speed wired connection to your extended network, ideal for devices that benefit from a direct link.

Maintenance
- Optimal Placement: For best performance, place the extender in an open area, away from obstructions like large metal objects, concrete walls, or other electronic devices that may cause interference.
- Firmware Updates: Periodically check the official AERVY support website for any available firmware updates to ensure optimal performance, security, and compatibility.
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners, aerosols, or abrasive materials, as these can damage the device.
- Restarting: If you experience network issues, such as intermittent connectivity or slow speeds, try restarting the extender by unplugging it from the power outlet for 10 seconds and then plugging it back in.
Troubleshooting
- No Power: Ensure the extender is securely plugged into a working power outlet. Verify that the power indicator light is on. If not, try a different outlet.
- Cannot Connect to Extender's Wi-Fi: During initial setup, ensure you are connecting to the extender's default SSID. After setup, ensure your device is connecting to the newly created extended network's SSID.
- Weak Signal from Extender: Reposition the extender closer to your main router. Ensure there are no major physical obstructions (e.g., thick walls, large appliances) between the extender and the router. The extender's signal indicator lights can help determine optimal placement.
- No Internet Access: Verify that your main router has an active internet connection. Restart both your main router and the extender. Check all cable connections if using the Ethernet port.
- WPS Setup Failure: Ensure you press the WPS button on both the router and extender within the specified time frame (usually 2 minutes). If WPS setup consistently fails, try the web browser setup method.
- Slow Speeds: Ensure the extender is placed in an area with good signal strength from the main router. Placing it too far from the router will result in slower extended speeds. Reduce the number of connected devices if network congestion is suspected.
