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 connection among your entire network, while the 4-port full duplex 10/100 Switch
jump-starts your wired-Ethernet network. Connect four PCs directly, or daisychain 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 (draft 802.11g) at 54Mbps. The second Access
Point radio operates in the 5GHz band, and supports Wireless-A (802.11a) networking, 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 Router’s Functions
Simply put, a router is a network device that connects two networks together. A
wireless router connects three networks.
In this instance, the Router connects your wired network and wireless network,
or the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these 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 network. 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.
Dual-Band Wireless A+G Broadband Router
Remember that the Router’s ports connect to two sides. The 10/100 LAN ports
connect to the LAN, and the Internet port connects to the Internet. The LAN
ports transmit data at 10 Mbps or 100 Mbps, and the broadband port, or
Internet port, transmits data at 10/100 Mbps. Your wireless devices connect to
the Router through either 802.11a, 802.11b, or draft-802.11g wireless technology.
IP Addresses
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, including
PCs, print servers, and routers, requires an IP address to identify its “location,” 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.
Note: 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 7: The Router’s
Web-based Utility.”
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.
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 automatically assign it a new dynamic IP address.
Instant Wireless® Series
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 network device, such as the Router. By default, the Router’s DHCP Server function 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 7: The
Router’s Web-based Utility.”

Note: Even if you assign a static IP address to a PC, other PCs can
still use DHCP’s dynamic IP addressing, as long as the static IP
address is not within the DHCP range of the LAN IP Addresses.
If the dynamic IP addressing fails to provide a dynamic IP address,
refer to “Appendix A: Troubleshooting.”

The Reset Button
The Reset button can be used in one of two ways:
1. 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.
This will reboot the Router while keeping all of the Router’s settings.
2. 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.
This will restore factory defaults and clear all of the Router’s settings,
including settings such as a new password or wireless settings.

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.

Chapter 3: Connect the Router
Overview
Note: These directions on connecting the Router are provided only
to help when you are making the connections. If you are using the
Setup Wizard, make your connections only when the Wizard asks.
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 information 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 and Boot-Up.” 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.”

Wireless Connection to a PC
Chapter 4: Configure the PCs
If you want to use a wireless connection to access the Router, follow these
instructions:
Overview
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.
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.
2. Connect an Ethernet network cable
from your cable or DSL modem to the
Internet port on the Router’s rear
panel, as shown in Figure 3-4. This is
the only port that will work for your
modem connection.
3. Power on the cable or DSL modem.
The instructions in this chapter will help you configure each of your computers to be able to communicate with the Router.
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.
Figure 3-4
4. Connect the power adapter to the Power port, and then plug the power
adapter into a power outlet.
Note: You should always plug the Router’s power adapter into a power
strip with surge protection.
• 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 selftest 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-a or linksys-g (which are
the Router’s default SSID settings, depending upon the wireless devices you
are using), 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.”
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 settings 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, setup the Router, either by using the Setup Wizard as shown
in “Chapter 5: Setting Up the Dual-Band Wireless A+G Broadband Router” or
by using the Web-based Utility as shown in “Chapter 6: Configuring the
Router’s Basic Settings with the Web-based Utility”.
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 instructions to install TCP/IP.
Note: You should always change the SSID from its default, linksys,
and enable WEP encryption.
