Troubleshooting
| Problem | Solution |
|---|---|
| Extender not powering on. | Ensure the extender is securely plugged into a working power outlet. Try a different outlet. |
| Cannot connect to the extender's Wi-Fi. | Ensure the extender is powered on. If you've already set it up, connect to the extended network name. If not, connect to the default `TP-Link_Extender` network. |
| Poor signal strength (Red Signal LED). | Relocate the extender closer to your main router. Ensure there are no major obstructions (thick walls, large metal objects) between the extender and the router. |
| Extended network has no internet access. | Verify that your main router has internet access. Reconfigure the extender to ensure it's correctly connected to your main router's Wi-Fi. Check the Signal LED for a strong connection. |
| Forgot extender's management password. | Perform a factory reset on the extender. Use a pin to press and hold the Reset button (usually a small hole) for about 5-10 seconds until the LEDs flash. Then, set up the extender again. |
