Hi,
Thank you for your review. If you are experiencing difficulty connecting the extender to your router, we recommend setting up the device in the same room as your router, then relocating it after setup is complete. We also suggest re-verifying your router's Wi-Fi password during setup, or if using the WPS setup method, ensuring the WPS process is performed in the correct order. The extender's indicator LEDs will help you determine which position in your home is ideal.
We also highly recommend ensuring the extender's firmware is fully up-to-date using the steps outlined in FAQ 1406 on our official website. To locate this FAQ, visit our website and enter 1406 in the top-right search field, then click the corresponding FAQ in the search results.
Best Regards,
TP-Link Support
