How to Change the PPPoA Username & Password

Updated February 21, 2017

PPPoA is an acronym for Point-to-Point Protocol over ATM, a networking technology. This technology is built in to the router that is connected to your DSL line. In order to access your Internet connection, you need to enter a username and password. Once you are logged in, the PPPoA technology ensures the connection between the router and your ISP remains constant. If the connection drops, you will need to log in again to re-establish your connection through the router. Changing your PPPoA username and password is straightforward and takes only a few minutes.

Launch your default Web browser. Click once in the empty navigation bar at the top of the browser window. Type the URL for the router set-up page in this field -- consult your router's user manual for this information. The URL will have four numbers separated by periods and will look something like this: "" Press the "Enter" key.

Enter your password for the router in the text field of the next screen that opens in your Web browser. If no password was created when you installed the router, leave this field blank. Click "Continue" to open the router's set-up menu.

Select "PPPoA" from the left side of the menu page. Click the "Security" tab on the next Web page that appears.

Erase the username and password displayed in their respective text fields. Type a new username and password into these fields.

Click "Save settings" and then click the "Home menu" button. Click "Exit"
