Here in this case you can reset your Orbi RBR 40 to factory defaults. To know more about the reset process, follow the procedure given below:
- Ensure that the Orbi device is powered on.
- Now, with the help of a paper clip, you can press the reset button. Keep holding it for a few seconds until the Power LED on the device blinks amber.
- The Orbi device has been reset to factory defaults successfully.
