1. Start by checking that the power cable of your Wi-Fi Bridge is properly plugged into an electrical outlet.
2. Ensure that an Ethernet cable correctly connects your TV Box to your Wi-Fi Bridge.
3. If the Wireless indicator light on the Wi-Fi Bridge is off, it means you need to resynchronize the Wi-Fi Bridge with your b-box.
4. Make sure the Link Quality indicator light is on and green. This indicates that the signal received by your Wi-Fi Bridge is sufficient. If not, try to position your Wi-Fi Bridge as close to your b-box as possible.

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