Dual-Band Wireless A/G Broadband Router
Chapter 1: Introduction
The Dual-Band Wireless A/G Broadband Router is like four devices in one
box! The Router function lets you securely share one high-speed Internet con-
nection among your entire network, while the 4-port full duplex 10/100 Switch
jump-starts your wired-Ethernet network. Connect four PCs directly, or daisy-
chain out to more hubs and switches to create as big a network as you need.
The Dual-Band Wireless A/G Broadband Router also contains two Wireless
Access Points, supporting all three wireless networking specifications. The
first Access Point uses the 2.4GHz radio band, supporting both the popular and
inexpensive Wireless-B (802.11b) standard at 11Mbps, and the new, almost
five times faster, Wireless-G (802.11g) at 54Mbps. The second Access Point
radio operates in the 5GHz band, and supports Wireless-A (802.11a) network-
ing, also at 54Mbps. Since the two radios operate in different bands, they can
work simultaneously, blanketing your wireless zone with bandwidth.
To protect your data and privacy, the Dual-Band Wireless A/G Broadband
Router can encrypt all wireless transmissions. The MAC Address filter lets
you decide exactly who has access to your wireless network. The Router also
serves as a DHCP Server, has NAT technology to protect against Internet
intruders, DMZ capability, supports VPN pass-through, and can be configured
to filter internal users' access to the Internet. Configuration is a snap with the
web browser-based configuration utility.
With the Linksys Dual-Band Wireless A/G Broadband Router at the center of
your home or office network, you can share a high-speed Internet connection,
files, printers, and multi-player games with the flexibility, speed, and security
you need!

The Dual-Band Wireless A/G Broadband Router
Dual-Band Wireless A/G Broadband Router
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, includ-
ing PCs, print servers, and routers, requires an IP address to identify its “loca-
tion,” or address, on the network. This applies to both the Internet and LAN
connections. There are two ways of assigning an IP address to your network
devices. You can assign static IP addresses or use the Router to assign IP
addresses dynamically.
Static IP Addresses
A static IP address is a fixed IP address that you assign manually to a PC or
other device on the network. Since a static IP address remains valid until you
disable it, static IP addressing ensures that the device assigned it will always
have that same IP address until you change it. Static IP addresses must be
unique and are commonly used with network devices such as server PCs or
print servers.
If you use the Router to share your cable or DSL Internet connection, contact
your ISP to find out if they have assigned a static IP address to your account.
If so, you will need that static IP address when configuring the Router. You can
get that information from your ISP.
IP Addresses
Note: Since the Router is a device that connects two networks, it
needs two IP addresses—one for the LAN, and one for the Internet. In
this User Guide, you’ll see references to the “Internet IP address” and
the “LAN IP address.”
Since the Router uses NAT technology, the only IP address that can be
seen from the Internet for your network is the Router’s Internet IP
address.
However, even this Internet IP address can be blocked, so that the
Router and network seem invisible to the Internet—see the Block
WAN Requests description under Filters in “Chapter 6: The Router’s
Web-based Utility.”

Simply put, a router is a network device that connects two networks together.
In this instance, the Router connects your Local Area Network (LAN), or the
group of PCs in your home or office, to the Internet. The Router processes and
regulates the data that travels between these two networks.
The Router’s NAT feature protects your network of PCs so users on the public,
Internet side cannot “see” your PCs. This is how your network remains private.
The Router protects your network by inspecting every packet coming in
through the Internet port before delivery to the appropriate PC on your net-
work. The Router inspects Internet port services like the web server, ftp server,
or other Internet applications, and, if allowed, it will forward the packet to the
appropriate PC on the LAN side.
Remember that the Router’s ports connect to two sides. The LAN ports connect
to the LAN, and the Internet port connects to the Internet. The LAN and
Internet ports transmit data at 10/100Mbps.

•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

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 Dual-Band
Wireless A/G Broadband Router,” most users will only need to use the follow-
ing 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
Router, you may follow the instructions in the Quick Installation guide

The Reset button can be used in one of two ways:
1. Reboot the Router while keeping all of its settings.
If the Router is having problems connecting to the Internet, press the Reset
button for just a moment with a paper clip or a pencil tip. This clears up any
jammed connections, and is similar to pressing the Reset button on your PC
to reboot it.
2. Restore the Router’s factory defaults and clear all of its settings, including a
new password or wireless settings.
If you are experiencing extreme problems with the Router and have tried all
other troubleshooting measures, press the Reset Button and hold it down for
10 seconds.
Chapter 2: Getting to Know
the Dual-Band Wireless A/G
Broadband Router
The Router’s ports are located on the Router’s back panel, as shown in Figure
2-1.
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 connect 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.

tection.
Figure 3-2
Figure 3-3
Have you checked that the Link/Act LEDs for all your LAN con-
nections and the Link LED for your Internet connection light up?
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.
Overview
Wired Connection to a PC
Figure 3-1

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.”
1312
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.
Go to “Chapter 4: Configure the PCs.”

3. The web-based utility will appear with the Setup tab selected. Select the
time zone for your location. If your location experiences daylight savings,
leave the checkmark in the box next to Automatically adjust clock for day-
light saving changes.
4. Based on the setup instructions from your ISP, you may need to provide the
Host Name and Domain Name (usually cable ISPs require them). These
fields allow you to provide a host name and domain name for the Router
and are usually left blank.
The values for the Router’s LAN IP Address and Subnet Mask are shown
on the Setup screen. The default values are 192.168.1.1 for the IP Address
and 255.255.255.0 for the Subnet Mask.
5. The Router supports four connection types: Automatic Configuration -
DHCP (obtain an IP automatically), Static IP, PPPoE, and PPTP. These
types are listed in the drop-down menu for the Configuration Type setting.
Each Setup screen and available features will differ depending on what kind
of connection type you select. Proceed to the instructions for the connec-
tion type you are using, and then continue to step 6.
IMPORTANT: If you have previously enabled any Internet-sharing
proxy server software on any of your PCs, you must disable it now.
Some examples of Internet-sharing software are Internet LanBridge,
Wingate, ICS, and Sygate. To disable your Internet-sharing software:
• If you are running Netscape Navigator, click Edit, Preferences,
Advanced, and Proxies. Click Direct Connection to the Internet.
• If you are running Internet Explorer 5.x or higher, click Tools,
Settings, Control Panel, Internet Options, Connections, and
LAN Settings. Remove checkmarks from all three boxes. Click the
OK button to continue.
You must also disable any Internet log-on software (such as Ivasion
Winpoet or Enternet 300) and any firewall software (such as
ZoneAlarm and Watchdog) on all of your PCs.
Chapter 5: Configure the Router’s
Basic Settings
This chapter will show you how to configure the Router to function in your
network and gain access to the Internet through your Internet Service Provider
(ISP). Detailed description of the Router’s web-based utility can be found in
“Chapter 6: The Router’s Web-based Utility.”
The instructions from your ISP tell you how to set up your PC for Internet
access. Because you are now using the Router to share Internet access among
several computers, you will use the setup information to configure the Router
instead of your PC. You only need to configure the Router once using the first
computer you set up.
1. Open your web browser. Enter http://192.168.1.1 (the Router’s default IP
address) in the web
browser’s Address
field, as shown in
Figure 5-1. Press
the Enter key.
2. An Enter Network Password window, shown in Figure 5-2, will appear.
(Windows XP users
will see a similar
screen.) Leave the
User Name field
empty, and enter
admin in lowercase
letters in the
Password field
(admin is the
default password).
Then, click the OK
button.
