A flashing white light on your Orbi satellite generally means the device is attempting to connect to the main router or is powering on. This is a normal stage during the setup, but if the white light continues to blink for more than a few minutes, it suggests that there is a connection issue. Orbi router and satellite should therefore be reset. Ensure they are oriented within range of each other without any barriers or interference affecting the signal. You might need to do a factory reset on the satellite and re-sync it with the router if the Orbi satellite flashing white problem persists. Doing so may help to restore your system to its normal state and ensure the seamless functioning of your Wi-Fi network.
