1. Start by checking that the power cable of your Wi-Fi Booster is properly plugged into an electrical outlet.
2. If you are using your Wi-Fi Booster to connect a TV Box, ensure that an Ethernet cable connects your TV Box to your Wi-Fi Booster.
3. If your Wi-Fi Booster is not connected by cable to your b-box, the Link Quality indicator light should be green, indicating that the signal received by the Wi-Fi Booster is sufficient. If not, try to position your Wi-Fi Booster as close to your b-box as possible.
4. If your Wi-Fi Booster is connected by cable to the b-box, ensure that the Ethernet cable is correctly plugged into one of the Ethernet ports of your Wi-Fi Booster on one end and your b-box on the other.

It is important to keep your Wi-Fi Booster in a clear location to avoid signal disturbances.
