If your Orbi satellite is flashing white, it usually means the satellite is trying to connect to the main router. Check the connection status by using a web browser to access the Orbi Login page in order to fix this. Make that both the satellite and the router are powered on and that they are within the router's range. Try resetting the satellite by holding down the reset button for ten seconds if the problem persists. Reset the satellite and reconnect it to the network to have flawless Wi-Fi service again in the entire house.
