Chapter 4: Configure the PCs
This chapter instructs you on how to configure your PCs to be DHCP clients,
if you have previously set static IP addresses on your PCs.
Chapter 5: Configure the Router’s Basic Settings
This chapter explains how to configure the Router using your web browser
and the Router’s web-based utility. You will configure the Router for Internet
access using the settings provided by your ISP.
When you’re finished with these basic steps, you will be ready to connect to the
Internet. You can also modify the Router’s settings further; for example, you
can adjust security features and other settings to enable online gaming (see
“Chapter 6: The Router’s Web-based Utility”).

Dynamic IP Addresses
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers.
These IP addresses are called “dynamic”
because they are only
temporarily
assigned to the PC or device.
After a certain
time period, they expire and may change. If a PC logs onto the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will auto-
matically assign it a new dynamic IP address.
DHCP (Dynamic Host Configuration Protocol) Servers
PCs and other network devices using dynamic IP addressing are assigned a new
IP address by a DHCP server. The PC or network device obtaining an IP
address is called the DHCP client. DHCP frees you from having to assign IP
addresses manually every time a new user is added to your network.
A DHCP server can either be a designated PC on the network or another net-
work device, such as the Router. By default, the Router’s DHCP Server func-
tion is enabled.
If you already have a DHCP server running on your network, you
must
disable
one of the two DHCP servers. If you run more than one DHCP server on your
network, you will experience network errors, such as conflicting IP addresses.
To disable DHCP on the Router, see the DHCP section in “Chapter 6: The
Router’s Web-based Utility.”
This User Guide covers the steps for setting up a network with the Router (see
Figure 1-1). After going through “Chapter 2: Getting to Know the Wireless-G
Broadband Router,” most users will only need to use the following chapters:
Chapter 3: Connect the Router
This chapter instructs you on how to connect a cable or DSL modem to the
Router and connect your PC(s) to the Router.
Router Setup Overview
Note:
You should always run the Setup CD-ROM to configure the
Router for Internet access. If you wish to manually configure the

Button and hold it down for
10 seconds.
Chapter 2: Getting to Know the
Wireless-G Broadband Router
The Router’s ports are located on the Router’s back panel.
Internet
The Internet port is where you connect your cable or
DSL modem through an Ethernet network cable.
Your modem connection will not work from any
other port.
Ports 1-4
These four LAN (Local Area Network) ports con-
nect to network devices, such as PCs, print servers,
and network attached storage (NAS). Each of the
ports will auto-detect whether a straight-through or
crossover cable is plugged into it, so there is no need
for an uplink port. Any one of the four ports can
serve as an uplink port to other network devices.
Power
The Power port is where you will connect the power
adapter.

If all of your
Link
LEDs are not lighting up, make sure that all your
cables are securely plugged in, and that all of your hardware is pow-
ered on properly. Verify that the modem is plugged into the Internet
port on the Router.
Chapter 3:Connect the Router
The Router’s setup consists of more than simply plugging hardware together.
You will have to configure your networked PCs to accept the IP addresses that
the Router assigns them (if applicable), and you will also have to configure the
Router with setting(s) provided by your Internet Service Provider (ISP).
The installation technician from your ISP should have left the setup informa-
tion for your modem with you after installing your broadband connection. If
not, you can call your ISP to request that data.
Once you have the setup information you need for your specific type of Internet
connection, you can begin installation and setup of the Router.
If you want to use a PC with an Ethernet adapter to configure the Router, go to
“Wired Connection to a PC.” If you want to use a PC with a wireless adapter
to configure the Router, go to “Wireless Connection to a PC and Boot-Up.”
1. Before you begin, make sure that all of
your network’s hardware is powered
off, including the Router, PCs, and
cable or DSL modem.
2. Connect one end of an Ethernet net-
work cable to one of the LAN ports
(labeled 1-4) on the back of the
Router, and the other end to an
Ethernet port on a PC.
Repeat this step to connect more PCs, a switch, or other network devices to
the Router.

Chapter 4: Configure the PCs
The instructions in this chapter will help you configure each of your comput-
ers to be able to communicate with the Router.
To do this, you need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically, so your PC can function as a DHCP client.
Computers use IP addresses to communicate with the Router and each other
across a network, such as the Internet.
First, find out which Windows operating system your computer is running. You
can find out by clicking the
Start
button. Read the side panel of the Start menu
to find out which operating system your PC is running.
You may need to do this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your network set-
tings based on the type of Windows operating system you are using. Make sure
that an Ethernet or wireless adapter (also known as a network adapter) has been
successfully installed in each PC you will configure. Once you’ve configured
your computers, continue to “Chapter 5: Configure the Router’s Basic
Settings.”

Important:
By default Windows 98, 2000, Me, and XP has
TCP/IP installed and set to obtain an IP address automatically.
If your PC does not have TCP/IP installed, click
Start
and then
Help
. Search for the keyword
TCP/IP
. Then follow the instruc-
tions to install TCP/IP.
Overview
If you want to use a wireless connection to access the Router, follow these
instructions:
1. Before you begin, make sure that all of
your network’s hardware is powered
off, including the Router, PCs, and
cable or DSL modem.
2. Connect an Ethernet network cable
from your cable or DSL modem to the
Internet port on the Router’s rear
panel.
This is the only port that will
work for your modem connection.
3. Power on the cable or DSL modem.
4. Connect the power adapter to the Power port, and then plug the power
adapter into a power outlet.
The
Power
LED on the front panel will light up green as soon as the power
adapter is connected properly.
The
Diag
LED will light up red for a few seconds and turn off when the self-
test is complete. If this LED stays on for one minute or longer, see “Appendix
A: Troubleshooting.”
4. Power on one of the PCs on your wireless network(s).
5. For initial access to the Router through a wireless connection, make sure the
PC’s wireless adapter has its SSID set to
linksys
(the Router’s default set-
ting), and its WEP encryption is
disabled
. After you have accessed the
Router, you can change the Router and this PC’s adapter settings to match
the your usual network settings.
The Router’s hardware installation is now complete.
