Wireless-G Broadband Router

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Broadband Router. The Wireless-G Broadband Router will allow
you to network wirelessly better than ever, sharing Internet Access, files and fun, easily and securely.

How does the Wireless-G Broadband Router do all of this? A router is a device that allows access to an Internet
connection over a network. With the Wireless-G Broadband Router, this access can be shared over the four
switched ports or over via the wireless broadcast at either 11Mbps Wireless-B or 54Mbps Wireless-G. In addition,
the Wireless-G standard provides greater security opportunities while the router’s switched ports are protected
through Stateful Packet Inspection (SPI) and a NAT firewall. All of these security features, as well as full
configurability is accessed through the easy to use browser-based utility.

But what does all of this mean?

Networks are useful tools for sharing computer resources. 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 are not only useful in homes and offices, they can also 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".

LAN (Local Area Network): The
computers and networking products
that make up the network in your home
or office

PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wireless Local Area Network. The Wireless-G Broadband Router bridges wireless networks of both

802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.

With your networks all connected, wired, wireless, and the Internet, you can now share files, Internet access,
even play games. All the while, the Wireless-G Broadband Router protects your networks from unauthorized and
unwelcome users.

Use the instructions in this Guide to help you connect the Wireless-G Broadband Router, set it up, and configure it
to bridge your different networks. These instructions should be all you need to get the most out of the Wireless-G
Broadband Router.

Dual-Band Wireless Access Point

Chapter 2: Planning your Wireless Network

Network Topology

A wireless LAN is a group of computers, each equipped with one Linksys wireless adapter. Computers in a
wireless LAN must be configured to share the same radio channel.

The Linksys wireless adapters provide access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an infrastructure configuration. A group of Linksys wireless adapter users and a
Wireless-G Broadband Router compose a Basic Service Set (BSS). Each Linksys wireless adapter PC in a BSS can
talk to any computer in a wired LAN infrastructure via the Wireless-G Broadband Router.

An infrastructure configuration extends the accessibility of a Linksys wireless adapter PC to a wired LAN, and
doubles the effective wireless transmission range for two Linksys wireless adapter PCs. Since the Wireless-G
Broadband Router is able to forward data within its BSS, the effective transmission range in an infrastructure LAN
is doubled.

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

Roaming

Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured
as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All PCs
equipped with a Linksys wireless adapter within one ESS must be configured with the same ESS ID and use the
same radio channel.

Before enabling an ESS with roaming capability, choosing a feasible radio channel and optimum Wireless-G
Broadband Router position is recommended. Proper router positioning combined with a clear radio signal will
greatly enhance performance.

Overview

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.

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.

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,
continue to “Chapter 6: Using the Router’s Web-Based Utility.”

IMPORTANT: 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.

(WEP Encryption, Wireless and LAN settings, etc.),
and replace them with the factory defaults. Do not
reset the Access Point if you want to retain these
settings.

The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports.
Wireless Setup is performed through the Wireless tab.

Router IP

This presents both the Router’s IP Address and Subnet Mask as seen by your network.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. 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.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then click the Disable radio button (no other DHCP features will be available).

Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller
than 192.168.1.253. The default Starting IP Address is 192.168.1.100.

Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign

IP addresses to. This number cannot be greater than 253. The default is 50.

Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.
The default is 0 minutes, which means one day.

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.

Time Setting

Change the time zone in which your network functions from this pull down menu. (You can even automatically
adjust for daylight savings time.)
