DSL modems differ from some other modem types in that they always need to be configured for use on your DSL service before they will work. This is done by connecting your DSL modem to your computer and accessing a configuration page that allows you to manipulate all the internal settings on the modem. If you wish to access or "hack" the modem in this manner, follow a simple guide.

Connect one end of the ethernet cable to the DSL modem's ethernet port, pushing the plastic connector in until it makes a soft clicking sound.

Connect the other end of the ethernet cable to your computer's ethernet port.

Open an Internet browser and type the modem's local access IP address into the address bar. Press the Enter key to access the configuration page. If you do not know the local access IP, look for a sticker on the modem itself or in the modem's documentation. You can also contact the manufacturer of the modem or the technical support department of your Internet service provider and have them tell you the local access IP. You may be prompted to enter an admin username and password; this information should also be printed in the modem's documentation.

Configure the modem. From the local access page, you can specify the connection type, monitor the health and strength of the connection, apply custom security settings, and change your administration password. Depending on the model of the modem and the type of Internet connection you use, you may have many other options that you can manipulate to your liking.
