Cisco | ADSL Modem Router | This article describes how to manually configure a Linksys Router

This article describes how to manually configure a Linksys Router for broadband DSL
that uses PPPoE (Point-to-Point Protocol over Ethernet) for authentication. For
automatic configuration options, please try:
1. Linksys Easy Connect (see Answer ID 1650 for more information), or
2. The Linksys Setup Wizard CD-ROM software that came with your Linksys
Router. Simply insert this CD-ROM into an online computer before connecting
your Linksys Router, and the Wizard will provide step-by-step instructions on
how to install and configure your router.
If you are unable to set up your Linksys Router by using one of the above
options, use the steps below to manually configure your router.
NOTE: It is recommended that you print this article for offline reference.
STEP 1: Before You Begin
In order to set up your Linksys Router, be sure to first have the following:
1. A Linksys Router.
2. A DSL modem.
3. A working computer that can be wired in directly to the router for initial
configuration and testing.
4. Two (2) standard Ethernet network cables. Linksys Routers come with one (1)
standard network cable that you can use.
5. The PPPoE DSL username and password assigned by your Internet Service
Provider. Depending on the provider, your username format might be similar to
username, vzn123456, or an e-mail address (username@isp.net). If you are not
sure what your username and password are, contact your Internet Service Provider
for more information.
STEP 2: Check Your Internet Connection
Before installing your Linksys Router, it is important to first verify that you can
successfully access the Internet by connecting directly to your modem (without your
Linksys Router installed).
1. If you are connecting for the first time, follow the instructions provided by your
provider to set up your modem and computer for online access.
2. Verify that you are able to access the Internet without any problems. If you are
not able to get a connection, contact your Internet Service Provider for assistance.
When you are able to access the Internet using your modem, continue to Step 3 and
proceed with the installation of your Linksys Router.
STEP 3: Connect the Hardware
Follow these steps to connect your Linksys Router to your modem and computer.
1. Shut down your computer and unplug the power cords connected to your modem
and Linksys Router if they are currently powered on.
2. Disconnect the network cable that connects to the back of your computer.
3. Connect the network cable that you just removed to the Internet port (or WAN
port) located on the back of your Linksys Router. Your modem should now be
connected to your Linksys Router.
4. Connect a second network cable back into your computer (into the same port that
was disconnected in #2).
5. Connect the other end of the second network cable to one of the numbered ports
located on the back of your Linksys Router (labeled 1, 2, 3, 4, etc.). Your
computer should now be connected to your Linksys Router.
The following diagram shows how your network should be connected. Verify
that your connections are correct, and continue to the next step.
6. Plug the included power adapter into the router’s Power port. Then, plug the
other end of the power adapter into a nearby electrical outlet to supply power to
your router.
7. Turn on your computer.
Do not turn on your modem at this time. Only your router and computer should
be turned on for Step 4.
STEP 4: Configure the Router
Follow these steps to configure your Linksys Router.

such as Internet Explorer or Netscape.
2. Type http://192.168.1.1 into your browser’s Address or Location bar and click Go
or press the [Enter] key on your keyboard. The IP address 192.168.1.1 is the
default IP address of Linksys Routers.
3. A user name and password prompt will appear. Leave the user name field blank
(empty), and type in admin (lowercase) for the password. The password admin is
the default password of Linksys Routers.
