The Arris TM502G modem allows you to connect to the Internet via a DSL connection. Although you can usually plug the modem into your computer and begin surfing the Web, you can log into the device and change a variety of the settings, including the password and if you are connecting any wireless Internet routers to the modem. This process is completed without any special programming needed.
Power on the Arris TM502G modem and your computer.
