Check the back panel on your Time Warner router, gateway, or network device. The reset button is usually the smallest button and may be labeled RESET.
Press and hold the reset button for at least 20 seconds. Since the button is small, you may need use to a pen or similar object to press it all the way in.
Allow at least 5 minutes for the factory reset to complete. The device will power back on with factory default settings in place.
It's also possible to soft reset your device using the My Spectrum app. You can log into the website to make various network adjustments from any location.
