Planning Your Wireless Network

Network Topology

A wireless LAN is exactly like a regular LAN, except that each computer in the

LAN uses an Instant Wireless™ Network PC Card V2.5 to connect to the net-

work using no wires. Computers in a wireless LAN must be configured to

share the same radio channel.

The Instant Wireless™ Network PC Card V2.5 provides LAN access for wire-

less workstations. An integrated wireless and wired LAN is called an

Infrastructure configuration. A group of Instant Wireless™ Network PC Card

V2.5 users and an Access Point compose a Basic Service Set (BSS). Each PC

equipped with an Instant Wireless™ Network PC Card V2.5 in a BSS can talk

to any computer in a wired LAN infrastructure via the Access Point.

An infrastructure configuration extends the accessibility of an Instant

Wireless™ Network PC Card V2.5 PC to a wired LAN, and doubles the effec-

tive wireless transmission range for two Instant Wireless™ Network PC Card

V2.5 PCs. Since the Access Point is able to forward data within its BSS, the

effective transmission range in an infrastructure LAN is doubled.

The use of a unique ID in a BSS is essential. All computers that have Instant

Wireless™ Network PC Cards V2.5 configured without roaming options in an

independent BSS must be configured with a BSS ID (that is used in the BSS).

The Wireless LAN Infrastructure configuration is appropriate for enterprise-

scale wireless access to a central database, or as a wireless application for

mobile users.

Infrastructure mode also supports roaming capabilities for mobile users. More

than one BSS can be configured as an Extended Service Set (ESS). This con-

tinuous network allows users to roam freely within an ESS. All Instant

Wireless™ Network PC Card V2.5 PCs within one ESS must be configured

with the same ESS ID.

Before enabling an ESS with roaming capability, selecting a feasible radio

channel and optimum Access Point position is recommended. Proper Access

Point positioning combined with a clear radio signal will greatly enhance per-

formance.

2.The first tab across the top of the screen, labeled Install, should now be high-

lighted. Click on the Install button. The following screen should appear,

indicating that Windows is preparing the installation.

If, for whatever reason, you need to abort or terminate the installation, press

the Cancel button at any time during the installation. Otherwise the instal-

lation will continue automatically.

3. This screen will appear next, indicating that Windows is ready to continue

the installation. Click the Next button.

run the installation completely again before installing your hardware.

Installing the Drivers and

Configuration Utility for Windows

95, 98, ME, and 2000

Your new Linksys Instant Wireless™ Network PC Card V2.5 comes with an

automated software installation procedure for Windows 95, 98, Millennium,

and 2000. Windows NT users should refer to the next section. This new pro-

cedure automatically installs the drivers and Configuration Utility before you

install your hardware, so there’s no searching for the location of drivers. Again,

this step is taken before installing your hardware.

1. Before installing your adapter, insert the Setup CD into your CD-ROM drive.

Unless you have deactivated the auto-run feature of Windows, the following

screen should appear automatically.

If this screen does not appear automatically, you can access the installation

by pressing the Start button and choosing Run. In the drop-down box pro-

vided, type D:\setup.exe (where D: is the letter of your CD-ROM drive).

Alternately, double-click My Computer, and then double-click the CD-

ROM drive where the Setup CD is located. Double-click the Setup.exe icon

that appears.

4. The next screen that appears will be the Warranty Policy. Read the entire

policy by pressing the Page Down button on your keyboard. Click on the

Yes button if you agree, or No if you disagree. Clicking No will terminate

the installation. If you click Yes, the installation will continue.

5. The following window will appear next. To install the Configuration Utility

in the default directory (recommended), click the Next button. If you pre-

fer to install the Utility in another directory, click the Browse button, and

locate the preferred directory. Then click the Next button.

1. If you have chosen Infrastructure mode, the following screen will appear.

If you have chosen Ad-Hoc mode, skip to the next section.

You will be prompted to enter an SSID value in the box provided. The

SSID may be up to 32 characters in length and may include any character

on the keyboard. All SSID values on your wireless network must match. If

you are unsure, use the default value of “linksys.” Then, click the Next but-

ton. Note: All characters are case-sensitive.

2. The next screen to appear will be the Review Settings screen. Verify that

all the settings are correct and click the Next button to continue.

Unlike wired networks, wireless networks have two different modes in which

they may be set up: Infrastructure and Ad-Hoc. 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 net-

work or need to share a peripheral, such as a printer, with the wired network

computers, the wireless network should be set up in the Infrastructure mode.

The basis of Infrastructure mode centers around an access point, which serves

as the main point of communications in a wireless network. Access points

transmit data to PCs equipped with wireless network adapters, which can roam

within a certain

radial range of

the access point.

Multiple access

points can be

arranged to work

in succession to

extend the roam-

ing range, and

can be set up 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

an access point. The drawback of this mode is in the fact that, inAd-Hoc mode,

wireless-equipped computers are not able to communicate with computers on

a wired network.

And, of course, com-

munication between

the wireless-equipped

computers is limited

by the distance and

interference directly

between them.

Installing the Drivers and

Configuration Utility for Windows

The installation of the Network PC Card is different for users of Windows NT

because it is not a Plug-and-Play (PnP) system. This means it will not auto-

matically detect the presence of the Card when it is inserted. Consequently, the

order of the installation is different. The steps involved in the installation are

different, as well. If you are using any other operating system than Windows

NT, stop here and refer to the section called Installing the Drivers and

Configuration Utility forWindows 95, 98, ME, and 2000.

1. While the computer is restarting and before theWindows desktop appears,

locate an available Type II or Type III PCMCIA slot on your notebook com-

puter.

2. With the PCMCIA adapter’s 68-pin connector facing the PCMCIA slot

and the “Network PC Card” label facing up, slide the PCMCIA adapter com-

pletely into the PCMCIA slot.

The Hardware Installation is complete.
