- Press the WPS button on your router.
- Within two minutes, press the WPS button on your extender.
- The Signal LED on the extender should turn blue, indicating a successful connection.
5.2 Method 2: Using a Web Browser
If your router does not have a WPS button, or if the WPS method fails, you can set up the extender via a web browser.
- Plug the extender into an electrical outlet near your router.
- Wait for the Power LED on the extender to turn solid on.
- Connect your computer or mobile device to the extender's Wi-Fi network (e.g., 'TP-Link_Extender' or 'TP-Link_Extender_5G').
- Open a web browser and type http://tplinkrepeater.net or http://192.168.0.254 in the address bar.
- Create a login password when prompted.
- Follow the on-screen instructions to select your host network and configure the extender.
5.3 Finding the Optimal Location
After setup, relocate the extender to a location between your router and the Wi-Fi dead zone. The Signal LED will help you find the best spot:
- Blue: Good connection.
- Red: Too far from the router. Move the extender closer.
6. Operating Your Range Extender
6.1 Extending Wi-Fi Coverage
The TP-Link RE190 extends your existing Wi-Fi network, allowing devices to connect to the extender's network for improved signal strength and coverage in areas previously unreachable by your main router.

6.2 Dual Band Operation
The RE190 operates on both 2.4 GHz and 5 GHz bands. The 2.4 GHz band offers wider coverage, while the 5 GHz band provides faster speeds and is less prone to interference. Your devices will automatically connect to the optimal band for their needs.
7. Maintenance and Best Practices
- Firmware Updates: Regularly check the TP-Link website for firmware updates to ensure optimal performance and security.
- Placement: Avoid placing the extender near large metal objects, concrete walls, or devices that emit strong electromagnetic interference (e.g., microwave ovens, cordless phones).
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid or aerosol cleaners.
- Power Cycle: If the extender becomes unresponsive, try unplugging it from the power outlet for 10 seconds and then plugging it back in.
8. Troubleshooting
| Problem | Solution |
|---|---|
| Extender cannot connect to the router. | Ensure the extender is within range of the router. Try WPS setup again or use the web browser method. Check router settings (e.g., MAC filtering). |
| Signal LED is red. | The extender is too far from the router. Relocate it closer to the router until the Signal LED turns blue. |
| No internet access after connecting to extender. | Verify that your main router has internet access. Restart both the router and the extender. Check the extender's settings via the web interface. |
| Forgot extender's management password. | Perform a factory reset on the extender by pressing and holding the Reset button (usually a small pinhole) for 5-10 seconds while the extender is powered on. This will revert it to default settings. |
