Chapter 1: Introduction

Welcome

Thank you for choosing the Broadband Router. The Linksys Broadband Router with QoS is a kind of "splitter" for
your Internet connection. Just connect your DSL or Cable Modem to the Router, and all the computers in your
home or office can share the Internet at the same time. Use the built-in 4-port switch to attach four local PCs
directly, or daisy-chain out to more hubs and switches as your network grows. It has Auto MDI/MDI-X cross-over
detection so you don't have to worry about the cable type.

The Router's QoS (Quality of Service) feature lets you define the amount of the available bandwidth for each of
the devices on your network. This means that you can prioritize time-sensitive data like Voice Over IP phone calls
or streaming media ahead of less sensitive email and web surfing. The dual Internet ports let you optionally
connect a second Internet line for additional bandwidth.

Of course, once your computers are connected to the Internet through the Router, they can communicate with
each other too, sharing resources and files. All your computers can print on a shared printer connected
anywhere in the home. And you can share all kinds of files between computers, like music, digital pictures, and
other documents.

In addition to this, you can control access to the Internet through the Router’s Parental Control features. This
allows you to set a schedule, see what websites and programs are being used, optimize performance, and block
those sites you don’t wish to be accessed.

This user guide will give you all the information you need to connect, set up, and configure your Router.

broadband: an always-on,
fast Internet connection.

Chapter 2: Networking Basics

An Introduction to LANs

A Router is a network device that connects two networks together.

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.

LAN: the computers and networking products that
make up your local network

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.

NAT (Network Address Translation):
NAT technology translates IP
addresses of a local area network to a
different IP address for the Internet.

FTP (File Transfer Protocol): a protocol used
to transfer files over a TCP/IP network.

Packet: a unit of data sent over a network.

server: any computer whose function in a

network is to provide user access to files,
printing, communications, and other services.

Static IP address: a fixed address
assigned to a computer or device that
is connected to a network.

Dynamic IP address: a temporary IP
address assigned by a DHCP server.

DSL (Digital Subscriber Line): an always-on
broadband connection over traditional phone lines.

ISP (Internet Service Provider): a company that
provides access to the Internet.

Chapter 2: Networking Basics
An Introduction to LANs

Broadband Router

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.

PPPoE (Point to Point Protocol over Ethernet): a type of
broadband connection that provides authentication
(username and password) in addition to data transport.
