A+B Broadband Router
The Dual-Band Wireless A+B 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, 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+B Broadband Router also contains two wireless
access points, which let you connect with wirelessly networked PCs using
either the popular 2.4GHz, 802.11b standard at 11Mbps, or the new, almost five
times faster, 5GHz, 802.11a standard. Since both standards are built-in, you can
protect your investment in existing 802.11b equipment today, and migrate to
the 802.11a standard as your needs grow.
In addition to up to 152-bit encryption of wireless transmissions, the two access
points in the Dual-Band Wireless A+B Broadband Router support the industrial-strength wireless security of 802.1x authentication and authorization. The
Router also serves as a DHCP server, has NAT technology to protect against
Internet intruders, 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+B 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!

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.
The Router’s Functions
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 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.
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.
Dual-Band Wireless A+B Broadband Router
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.”
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.
Instant Wireless® Series
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.
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.
Dual-Band Wireless A+B Broadband Router
This User Guide covers the steps for setting up a network with the Router. After
going through “Chapter 2: Getting to Know the Dual-Band Wireless A+B
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.
Notebook with
Wireless Adapter
Notebook with
Wireless Adapter
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 6: 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.”
Router Setup Overview
Note: You should always you run the Setup Wizard 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 or this User Guide.

• 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

Your modem connection will not work from any
other port.
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.
The Power port is where you will connect the power
adapter.

Chapter 3: Connect the Router
Overview
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.”

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.
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.
The instructions in this chapter will help you configure each of your computers 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.
Figure 3-4
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.

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 selftest is complete. If this LED stays on for one minute or longer, see “Appendix
A: Troubleshooting.”
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, 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 instructions to install TCP/IP.
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 setting), 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.
Note: You should always change the SSID from its default, linksys,
and enable WEP encryption.

3. The web-based utility will appear with the Setup tab selected. 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.
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.”

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.
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.
4. 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 connection type you are using, and then continue to step 5.

Static DNS 1-3 The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will
provide you with at least one DNS Server IP Address. If you wish to use another, type that IP Address in one of these fields. You can type up to three DNS
Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers.
WINS The Windows Internet Naming Service (WINS) manages each PC’s
interaction with the Internet. If you use a WINS server, enter that server’s IP
Address here. Otherwise, leave this blank.

If you choose to enable the Router’s DHCP server option, you must configure all
of your network PCs to connect to a DHCP server (the Router), and make sure
there is no other DHCP server on your network.
If you disable the Router’s DHCP server function, you must have a separate
DHCP server for your network, or you must configure the IP Address, Subnet
Mask, and DNS for each network computer (make sure each IP Address is
unique).
Currently Assigned: DHCP Clients Table Click the DHCP Clients Table
button to view the list of PCs that are given IP addresses by the Router. For each
PC, the list shows the client hostname, IP address, MAC address, and and the
amount of DHCP client lease time left. Click the Refresh button to display the
most current information.

Upgrade Firmware New firmware versions are posted at www.linksys.com
and can be downloaded for free. If the Router already works well, there’s no
need to download a newer firmware version, unless that version has a new feature that you want to use. (To learn about any new firmware with new features,
visit www.linksys.com.) Loading new firmware onto the Router does not always
enhance the speed or the quality of your connection.
Note: By upgrading the Router’s firmware, you may lose the Router’s
configuration settings.
