The factory reset button is typically found on the back of the router. Look for a small button on the back panel.
To initiate a factory reset, press and hold the button for at least 10 seconds. You may need to use a pen to push the button all the way in.
When the front panel lights turn off, the factory reset has been initiated.
Wait a few minutes for the reset to complete—the reset is done when the Power light turns on.
