You can reset the router on your home network to its factory settings using the reset switch. A router connects two networks, such as Internet and your home network. Router devices sold for consumers typically include components that let all the computers on your network communicate with one another as well as the Internet. If your router has become unmanageable, or you have forgotten the password and you need to log into it, you may wish to restore it to a factory default condition and rebuild your network settings.
Unplug all cables from the router except the power cable. Power on the router.
