Introduction

The AirConnect

wireless network offers performance comparable to Ethernet

networks, but without the restraints of network cables. The AirConnect product

family includes the 3CRWE73796B wireless PC Card described in this manual.

Features

AirConnect adapters use IEEE 802.11 B direct-sequence-based technology to

extend the range and versatility of a network. They provide a high-capacity link

across multiple access points within large or small indoor environments.

AirConnect product-family features include:

■

A bridging architecture that allows communication between wired network

devices and mobile devices.

■

Compliance with IEEE 802.11 B speciﬁcation, an open architecture that allows

AirConnect devices to communicate with wireless devices from other

manufacturers.

■

Extended roaming to allow mobile devices to roam throughout large facilities

while remaining connected to the LAN.

■

Ad hoc mode that allows notebook PC users to create an instant network to

share data anywhere and anytime without the need for an access point.

AirConnect PC Card operating features include:

■

Support for standard NDIS (Network Driver Interface Speciﬁcation) and drivers.

■

Support for Windows Millennium Edition (Me), Windows 2000, Windows 98,

Windows 95B (OSR 2), Windows NT 4.0 (with Service Pack 3.0 or greater), and

Windows CE 2.11 and 3.0.

■

Card and Socket Services support, including SystemSoft, CardSoft, and

CardWizard.

■

Plug and Play support.

■

Power management.

■

Low-power operation for battery-powered devices with PC Card slots.

Installation Overview

AirConnect Wireless LAN cards support a maximum data rate of 11 Mbps. (The

data rate drops back to 5.5, 2, or 1 Mbps when the adapter cannot establish or

maintain an 11 Mbps association.) Factors that can affect the data rate include:

■

A separation or change in signal strength between the Access Point and the

wireless client

■

The ratio of packets transmitted to transmissions attempted falling below a

preset threshold

■

The wireless client ﬁnding and switching to another Access Point with a higher

transmit rate

Roaming means the AirConnect PC Card will maintain your network connection

as you roam between Access Points in the same subnet. You can also roam across

routers, depending on how your extended roaming conﬁguration is set. When

conﬁgured for extended roaming, the wireless client retains its network address as

it moves between subnets, between Ethernet segments, or from an Ethernet

segment to a wireless LAN. See “Easy Setup” on page 13 for details.

The wireless LAN PC Card supports

Continuous Active

and

Power Save Polling

power-management modes.

■

Continuous Active Mode

, the radio that establishes and maintains the link to

the network remains on. Continuous Active mode is not recommended for

battery powered devices.

■

Power Save Polling

conserves power by suspending the adapter’s

communication with an associated access point. The access point saves data

for transmission to the wireless client when it wakes at given intervals. When

the adapter wakes to check for data, it switches back into

Continuous Active

Mode

until it is ready to suspend communications again.

Installation Overview

Installing the AirConnect wireless network PC Card involves these tasks:

■

Running the Setup program from the

Installation CD

. See “Installing the

Drivers” on page 5.

■

Installing the PC Card. Do not install the card until instructed to do so by the

setup software. The procedure for installing the PC Card is described in

“Installing the PC Card” on page 20.

■

Installing the software, including the drivers for the card and the AirConnect

software utilities. See “Installing the Card Software” on page 6.

If you are reading this manual from the CD and want to install it on your hard

disk for easier access, see “Installing the Documentation” on page 6.

■

The card installation procedure covers basic conﬁguration. For advanced

conﬁguration options, or to explore the utilities available for managing and

conﬁguring the card, see “Software Conﬁguration, Tools, and Utilities” on

page 13.

Disk Factory

If you are installing the software on a computer that does not have a CD-ROM

drive, or if you choose to install the drivers manually, you will have to make

diskettes from the

Installation CD

. The setup application includes Disk Factory, a

utility for creating disks from CD. To use disk factory, you need access to a

computer with a CD-ROM drive and a ﬂoppy drive.

For a transfer of the driver software to a diskette, prepare a diskette labeled

Drivers.

For a transfer of the application software to diskette, prepare three disks labeled

as follows:

AirConnect Application Disk 1

AirConnect Application Disk 2

AirConnect Application Disk 3

2Put the Installation CD in the CD-ROM drive. The SETUP program should start

automatically. If it does not start, you can run it manually by selecting Run from

the Start menu.

3Select Create Diskettes.

4In the Disk Factory window, click Next.

5Select the software you want to transfer to diskette. If you select All, you will need

four ﬂoppy diskettes.

6Select the action, for example, Create and Verify Disks, and click Next.

7When you are ready to install the application software from diskette, put

AirConnect Application Disk 1 in the ﬂoppy drive and run SETUP.

If you are installing the drivers manually, use the Drivers diskette when the setup

wizard for your operating system prompts for drivers supplied by the

manufacturer.

2SOFTWARE INSTALLATION

Introduction Use the procedures described in this chapter to install the AirConnect wireless PC

Card software and drivers under Windows 95, Windows 98, Windows 2000, and

Windows Millennium Edition (Windows Me).

Installation Notes The following paragraphs described special considerations for particular operating

systems.

Windows 98 ■Installation under Windows 98 may result in a fatal error caused by the

UHCD.SYS ﬁle in the Windows 98 operating system. To avoid this problem, you

should update the UHCD.SYS ﬁle from v4.10.1998 to v4.10.2000. This update

is available from the following web site:

http://www.microsoft.com/windows98/downloads/contents/

WURecommended/systemupdata/Default.asp

■Note that the ﬁnal Windows 98 installation screen may take 30-60 seconds to

appear. Do not interrupt the installation if the PC appears to be taking too

much time to complete the installation.

Windows 95 Windows 95 users should note that the AirConnect wireless PC Card runs under

Windows 95 version B (OSR 2) or higher. If you do not know which version of

Windows 95 is installed on your computer, follow these steps:

1In the Control Panel, double-click System to display the System Properties dialog

box.

2Click the General Tab to display the Windows 95 version information.

Version B (also known as OSR 2) is identiﬁed as 4.00.950b.

Windows NT 4.0 Windows NT 4.0 users should refer to the driver installation instructions described

in “Installing Windows NT Drivers” on page 8.

Windows CE Windows CE users should refer to the “Installation for Windows CE” section.

Drivers for other operating systems are located at the 3Com Customer Support

Web site at:

http://support.3com.com

5CHAPTER 2: SOFTWARE INSTALLATION

Before Installing the

Drivers

Before installing the Windows 98 driver, you will need a copy of the Windows 98

installation media supplied with your computer or operating system. On many

Windows 98 systems, instead of a CD, the installation ﬁles are archived on the

hard disk in C:\WINDOWS\OPTIONS\CABS. On Windows 2000 systems, you

may be prompted to load operating system ﬁles from the Windows 2000

installation disk.

You will also need the AirConnect Installation CD supplied with your AirConnect

wireless PC Card. Along with other utilities, the Installation CD installs the

AirConnect Network Conﬁguration Properties Application in the Control Panel on

your system. Use this application to view and edit AirConnect WLAN adapter

settings.

If your site requires installation using diskettes, see “Disk Factory” on page 3.

Where the driver installation procedure mentions the Installation CD and CD-ROM

drive, use the diskettes and the ﬂoppy drive instead.

Installing the Drivers The following procedure is for installing drivers under Windows 95B (OSR 2),

Windows 98, Windows 2000, and Windows Me.

1Turn on your computer.

2Put the Installation CD in the CD-ROM drive.

The setup program should start automatically. If it does not start, you can run it

manually by selecting Run from the Start menu.

3From the 3Com AirConnect WLAN Installer, select Install AirConnect WLAN

Adapter. Follow the instructions as they appear.

4When prompted to insert the AirConnect PC Card, insert the card into the

notebook PC slot as described in “Installing the PC Card” on page 20.

The driver installation procedure will guide you through the steps standard for

your operating system. You will be asked to supply a CD or directory path

information for the Installation CD and your operating system software.

As part of the driver installation process, the setup program will install and open

the Network application in the Control Panel.

5Enter the name of the Wireless LAN Service Area of the wireless network to which

your computer will connect. The name you enter here must match exactly the

name assigned to the access point. Characters, capitalization, and spacing must

be identical.

6Save the conﬁguration settings and exit by clicking OK.

7Restart your computer.
