Welcome
Broadband Router with 2 Phone Ports
Chapter 1: Introduction
Welcome
Thank you for choosing the Broadband Router with 2 Phone Ports. This Router will allow your computers to share
a high-speed Internet connection as well as resources, including files and printers. And after you have set up
your Internet phone service, you will be able to make phone or fax calls using the Internet.
How does the Router do all of this? By connecting your computers and peripherals, including phones or fax
machines, to the Router and connecting the Router to your cable or DSL modem, then the Router can direct and
control communications for your network.
But what does all of this mean?
Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service,
your Internet access can now be shared by your phones or fax machines as well. You will be able to make phone
calls using the account you set up with your Internet phone service provider, even while you’re surfing the
Internet. Plus, you can access one printer from different computers and access data located on another
computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are
useful in homes and offices, but also can be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.
To create your network, install and set up the Router. To guide you through the process, Linksys strongly
recommends that you runthe Setup Wizard on the Setup CD-ROM. Ifyou prefer tomanually set up the Router, use
the instructions in the Quick Installation or this User Guide to help you. These instructions should be all you need
to get the most out of the Router.
ethernet: an IEEE standard network protocol
that specifies how data is placed on and
retrieved from a common transmission
medium.

Chapter 2: Networking Basics
An Introduction to Local Area Networks
Broadband Router with 2 Phone Ports
Chapter 2: Networking Basics
An Introduction to Local Area Networks
Simply put, a router is a network device that connects two networks together.
TheRouterconnects your localarea network (LAN), or the group ofPCs in your home or office, tothe Internet. The
Router processes and regulates the data that travels between these two networks.
The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet
cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by inspecting the
first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet
ports. 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.
The Use of IP Addresses
IP stands for Internet Protocol. Every device in 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 IP addresses to your network devices.
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 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.
A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called
dynamic because they are only temporarily assigned to the PC or other 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 assign it a new dynamic IP address.
dynamic ip address: a temporary IP
address assigned by a DHCP server.
static ip address: a fixed address
assigned to a computer or device that
is connected to a network.
nat (network address translation): NAT
technologytranslatesIP addressesofa
local area network to a different IP
address for the Internet.
dhcp (dynamic host configuration
protocol): a protocol that lets one
device on a local network, known as a
DHCP server, assign temporary IP
addresses to the other network
devices, typically computers.

5
Chapter 2: Networking Basics
The Use of IP Addresses
Broadband Router with 2 Phone Ports
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 Internet Connection Type is Obtain an IP automatically (DHCP).
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.
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 a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE).
PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a
connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.
By default, a DHCP server (on the LAN side) is enabled on the Router. 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 Basic Setup section in “Chapter 5: Configuring the Router.”

The Front Panel
The Router’s LEDs, which inform you about network activities, are located on the front panel.
Power Green. The Power LED lights up when the Router is powered on. If the LED is flashing, the
Router is booting up, running a system self-test, or upgrading its firmware.
Ethernet 1-3 Green. The Ethernet LEDserves two purposes. If the LED is solidly lit, the Router is connected
to a device through the corresponding port (Ethernet 1, 2, or 3). If the LED is flashing, the
Router is sending or receiving data over that port.
Phone 1-2 Green. The Phone LED is solidly lit when a telephone or fax machine has a registered
connection to your Internet phone service provider through the corresponding port (Phone 1 or
Phone 2). (The connection is registered if your Internet phone service account is active.) This
LED is not lit when there is no registered connection. It flashes when the phone is being used
or an incoming call has been detected.
Internet Green. The Internet LED lights up when the Router is connected to your cable or DSL modem.
If the LED is flashing, the Router is sending or receiving data over the Internet port.
