Note:

Do not confuse the user name and password used to access the web-based

manager with the ADSL account user name and password needed for PPP connections
to access the ADSL or network service provider’s network.

Logging in will bring up the Router/Bridge Configuration window of the web-based management module. In this
window, you will see the D-Link DSL-502G folder is open revealing its contents of three subfolders. These
subfolders contain menu buttons you can click on to see various menu screens used to configure the device for
connection to the WAN and other functions.

Figure 7. Web-based Manager Main Menu – First Time Log On

Configure the WAN Connection

Now that you have accessed the web-based manager, you can configure the device for the WAN connection. For
PPPoE and PPPoA connections, you will need to provide a User Name and Password used by your ISP for
authentication purposes. For “Bridged Ethernet” (RFC 1483) connections, a static IP address must be used. It is
necessary to supply IP settings for the WAN connection and other information discussed in Chapter 2,

Prepare

for Installation

.

All connection methods available to the Router are discussed in this chapter, beginning with PPPoA connections.
PPPoA is the default method used by the Router.

If you are using a PPPoE, IPoA, or Bridged Ethernet (RFC 1483) connection, it is necessary to change the
connection method. Please read

Changing the Connection Type
