Look for the factory reset button on the back of your modem or router—it’s likely red. This button is usually the smallest and may require a pen to press it all the way.
To initiate the factory reset, press and hold the button for at least 15 seconds. The reset will begin when the modem lights begin to flash.
Wait for at least 3-5 minutes for the factory reset to finish.
The Internet light will shine green when the process is complete.
