ADSL Setup - Manual Configuration

To configure the Router’s basic configuration settings without running the Setup

Wizard, you can access the menus used to configure ADSL Setup, Wireless Setup,

and LAN Setup settings directly from the

Setup

directory. To access the

ADSL Setup

menus for PPPoE/PPPoA, Dynamic IP Address, Static IP Address and Bridge Mode

connections, click on the

ADSL Setup

link button on the left side of the first menu

that appears when you successfully access the Web manager.

Choose the ADSL connection type used for your service listed under the heading

Manual ADSL Connection Setup, the menu changes according to the type of

connection to be configured. Configure the settings for the chosen Internet

Connection Type. Follow the instructions presented below for the type of connection

used for your ADSL service. The default Internet connection type is PPPoE/PPPoA.

Note

: Most users DO NOT need to change configuration settings for the Virtual Circuit at the bottom of this menu. Normally these settings are changed

only for special circumstances and applications. Do not change these unless your ISP has given specific instructions to do so.

For information about these configuration settings, go to “Configure VPI and VCI” on page 27.

.

To configure a PPPoE or PPPoA type WAN connection, follow these steps:

1. Under the

PPPoE/PPPoA

heading, type the

selected it when you set up the account with your ISP.

2. Choose the

Connection Type

from the pull-down menu located under the User

Name and Password entry fields. This defines both the connection protocol and

encapsulation method used for your ADSL service. The available options are

PPPoA VC-Mux

,

PPPoA LLC

,

PPPoE VC-Mux

and

PPPoE LLC

. If you have

not been provided specific information for the Connection Type setting, leave

the default setting.

IGMP select

Disable

. This will block all IP multicast traffic through the Router.

8. Leave the

Default Route

enabled if you want to use the Router as the default

route to the Internet for your LAN. Whenever a computer on the LAN attempts to
