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 Wide Area Network (WAN) that is
the Internet. The Router processes and regulates the data that travels between
these two networks.

An Introduction to LANs and WANs
Instant WirelessTMSeries
Think of the Router as a network device with two sides. The f irst side is made
up of your private Local Area Network (LAN) of PCs. The other, public side
is the Internet, or the Wide Area Network (WAN), outside of your home or
office.
The Router’s firew all (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your LAN, or network,
remains private. The Router protects your network by inspecting the first packet coming in from the WAN port before delivery to the final destination on the
LAN port. 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.
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 WAN and LAN connections.
There are two ways of assigning an IP address to your network devices.
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 insures that the device assigned it will have that
same IP address until you change it. Static IP addresses 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 the information from your ISP.
3
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 on to the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will assign
it a new dynamic IP address.
For DSL users, many ISPs may require you to log on with a user name and
password to gain access to the Internet. This is called “Point to Point Protocol
over Ethernet” or PPP oE. PPPoE is similar to a dial-up connection but does not
have a phone number to dial into, and PPPoE is a dedicated high-speed connection. PPPoE also will provide the Router with a dynamic IP address to
establish a connection to the Internet.
DHCP (Dynamic Host Configuration Protocol) Servers
DHCP frees you from having to assign IP addresses manuall y every time a new
user is added to your network. 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. The Router’s
WAN port is, by default, set as a DHCP client.
DHCP servers can either be a designated PC on the network or another netw ork
device, such as the Router. By default, a DHCP server is enabled on your
Router’s LAN ports. If you already have a DHCP server running on your network, you mustdisable 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 the Router’s DHCP function, see the
DHCP section in Chapter 3: Configuring the Router.
IP Addresses
NNoottee::
Since the Router is a device that connects two networks, it needs two
IP addresses—one for the LAN side, and one for the WAN side. In this User
Guide, you’ll see references to the “WAN IP address” and the “LAN IP
address.”
Since the Router has firewall security (NAT), only the Router’s WAN IP address
can be seen from the Internet.
However, even the WAN IP address can be blocked, so that the Router and
network seem invisible to the Internet—This is shown in the Filters section in
“Chapter 5: Using the Routers Web-Based Utility”.
NNoottee::
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 is not within the
DHCP range of the LAN IP Address.
If the Router’s DHCPfunction fails to provide a dynamic IP address for any
reason, please refer to Appendix A: Troubleshooting.

Pressing the Reset Button and holding it in for a few seconds will clear all
of the Router’s data and restore the factory defaults. This should be done
only if you are experiencing heavy routing problems, and only after you
have exhausted all of the other troubleshooting options. By resetting the
Router, you run the risk of creating conflicts between your PCs’ actual IP
Addresses and what the Router thinks their IP Addresses should be. You
may be forced to reboot each network PC.
If the Router locks up, simply press the reset button or power it down for
three to five seconds by removing the power cable from the Router’s
Power Port. Leaving the power off for too long could result in the loss of
network connections.
Figure 1-3
The
Router’s rear panel (as shown in Figure 1-2) is where all of its connections are
made.
WAN The WAN (Wide Area Network) Port is where you will con-
nect your cable or DSL modem with an Ethernet cable. Your
modem connection will not work from any other port.
Ports 1-4 These four LAN (Local Area Network) ports are where you
will connect networked devices, such as PCs, print servers,
and any other Ethernet devices you want to put on your network. If Port 4 is being used, the Uplink Port will not work.
Uplink The Uplink Port is where you can expand your network by
connecting to another switch or hub. Uplinking to another
switch or a hub is done by simply running a cable from the
Uplink Port to the other device. The Uplink Port is shared
with Port 4. If the Uplink port is being used, Por t 4 will not
work.
Power The Power Port is where you will connect the included AC
Power adapter.
Antenna Jacks The Antenna Jacks are where the included antennas are con-
nected.

Chapter 2: Connecting the Router
Before plugging everything together, it’s always a good idea to have everything
you’ll need to get the Router up and running. Depending upon how you configure the Router in Chapter 4: Configuring the Router, you may need some of the
following values from your ISP:
When connecting through a Static IP connection, be sure to have 1) Your
broadband-configured PC’s f ixed Internet IP Address, 2) Your broadbandconfigured PC’s Computer Name and Workgroup Name, 3) Your Subnet
Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.
When connecting through a PPPoE connection, be sure to have 1) Your
PPPoE User Name and 2) Your PPPoE Password.
The installation technician from your ISP should hav e left this information with
you after installing your broadband connection. If not, you can call your ISP to
request the data.
Once you have the above values, you can begin the Router’s installation and
setup.
Once you are sure that you have the above values on hand, you can begin the
Installation and Setup of the Router.
1. Power everything down, including your PCs, your cable or DSL modem and
the Router.
2. Connect an Ethernet cable from one of
your PC’s Ethernet ports to one of the
Router’s LAN ports (as shown in Figure 2-
1). Do the same with all the PCs you wish
to connect to the Router. (LAN Port 4 will
become inactive if you use the Uplink
port.)

For Wireless Connections: In addition to accessing the Router through an
Ethernet connection, a wireless connection can be used to access the Router.
After powering on the Router and connecting it to your modem, enter the
Router’s IP Address in the Address f ield of your wireless PC’s web-browser as
follows: http://192.168.1.1 and press Enter.
IImmppoorrttaanntt::
The Wireless Access Point Router with 4-Port Switch is
configured by default to work out of the box with all Linksys Wireless
Adapters. If you have changed the defaults on your Linksys Wireless
Adapters, or are using other wireless adapters, you must temporarily change your wireless adapter settings to: (SSID = linksys) in
order to initially access the Router wirelessly. After you have
accessed the Router with the default settings, you can change the
router settings to coincide with your Network settings and reset your
adapters.
IImmppoorrttaanntt::
Some ISPs—most notably some cable providers—configure their networks so that you do not have to enter a full Internet
address into your web browser or e-mail application to reach your
home page or receive your e-mail. If your Internet home page
address is something very simple, such as “www”, rather than
“www.linksys.com”, or your e-mail server’s address is something similar to “e-mail” or “pop3”, rather than “pop.mail.linksys.com”, you
won’t be able to properly configure the Router until you determine the
actual Internet addresses of your Web and e-mail connections.

A DHCP (Dynamic
Host Configuration
Protocol) Server
automatically
assigns IP addresses
to each computer on
its network. Unless
you already have
one, you should set
the Router up as a
DHCP server. This
is done on the DHCP
tab, shown in Figure
5-9.
• DHCP Server Click the Enable option to enable the Router’s DHCP serv-
er function If you already have a DHCP server on your network, set the
Router’s DHCP option to Disable.
• Starting IP Address Enter a numerical value for the DHCP server to start
with when issuing IP addresses.
• Number of DHCP users Enter the maximum number of PCs that will
require IP addresses assigned by the Router. No more than 253 computers
can be used. In order to determine the DHCP IP Address range, add the
starting IP address (e.g., 100) to the number of DHCP users. By default, as
shown in Figure 5-9, if you add 50 users, the range or IP Addresses will be
192.168.1.100 to 192.168.1.149.
• Client Lease Time The Client Lease Time is the amount of time a network
user will be allow ed connection to the Router with their current dynamic IP
address. Enter the amount of time, in minutes, that the user will be “leased”
