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 via the wireless broadcast at either 11Mbps for Wireless-B or 54Mbps for Wireless-G. In
addition, the WPA standard provides greater security opportunities while the whole network is protected through
a Stateful Packet Inspection (SPI) firewall and NAT technology. All of these security features, as well as full
configurability, are 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”.

PCs equipped with wireless cards or 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 and Internet
access—and even play games. All the while, the Wireless-G Broadband Router protects your networks from
unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Router. If you do not wish to run
the Setup Wizard on the Setup CD-ROM, then 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.

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each
computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same
frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the
same wireless network.

Ad-Hoc versus Infrastructure Mode

SSID: your wireless network’s name.

Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.
Choosing between these two modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the
Wireless-G Broadband Router, which serves as the main point of communications in a wireless network. The
Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial
range of the Router. You can arrange the Router and multiple access points to work in succession to extend the
roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well.

If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless­equipped computers is limited by the distance and interference directly between them.

Network Layout

The Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g
products. Now, products using these standards can communicate with each other.

Infrastructure: a wireless network
that is bridged to a wired network via
an access point.

Ad-hoc: a group of wireless devices
communicating directly to each other
(peer-to-peer) without the use of an
access point.

The Wireless-G Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook
Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and
USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Broadband Router will also
communicate with the Wireless PrintServer (WPS54GU2, WPS11) and Wireless Ethernet Bridges (WET54G,
WET11).

When you wish to connect your wireless network with your wired network, you can use the Wireless-G
Broadband Router’s four LAN ports. To add more ports, any of the Wireless-G Broadband Router's LAN ports can
be connected to any of Linksys's switches (such as the EZXS55W or EZXS88W).

Hardware Installation for Connection to Another Router

Before you install the Broadband Router, you must change the default IP address of the other router. This is
mandatory because both routers may be set to the same IP address by default. If you do not change the other
router’s default IP address, then you may not be able to set up the Broadband Router.

First, make sure the Broadband Router is NOT connected to your network. Then follow these instructions:

1. To access the other router’s Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the
other router’s default IP address, 192.168.1.1, in the Address field. Then press Enter.

NOTE: Steps 1-4 are instructions for a typical
Linksys router; however, if you are using a non­Linksys router, refer to the other router’s
documentation for instructions on how to change its
local IP address to 192.168.2.1.

2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the
password you have set (the default password is admin). Then click the OK button.

3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called
Local IP Address, which is set to 192.168.1.1. Change this to 192.168.2.1.

4. Click the Save Settings button to save your change, and then exit the Web-based Utility.

5. Power down your network devices. Now you will begin the hardware installation of Broadband Router.

Chapter 5: Configuring the PCs

Overview

The instructions in this chapter will help you configure each of your PCs, so they will 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: Configuring the Wireless-G Broadband Router.”

Configuring Windows 98SE and Millennium PCs

IMPORTANT: Important: By default Windows

98SE, 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.

1. Click the Start button. Select Settings and click the Control Panel icon. Double-click the Network icon.

2. On the Configuration tab, select the TCP/IP line for the applicable Ethernet adapter, as shown in Figure 5-1.
Do not choose a TCP/IP entry whose name mentions DUN, PPPoE, VPN, or AOL. If the word TCP/IP appears by
itself, select that line. Click the Properties button.

3. Click the IP Address tab. Select Obtain an IP address automatically. (See Figure 5-2.)

4. Now click the Gateway tab, and verify that the Installed Gateway field is blank. Click the OK button.

5. Click the OK button again. Windows may ask you for the original Windows installation disk or additional files.
Check for the files at c:\windows\options\cabs, or insert your Windows CD-ROM into your CD-ROM drive and
check the correct file location, e.g., D:\win98, D:\win9x, etc. (if “D” is the letter of your CD-ROM drive).

6. Windows may ask you to restart your PC. Click the Yes button. If Windows does not ask you to restart, restart
your computer anyway.
