# Introduction

NIH provides wireless access to NIH LANs at the Bethesda campus and
certain off‑campus locations. A wireless local area network (LAN) is a
flexible data communications system implemented as an extension to, or
as an alternative for, a wired LAN. Using radio frequency (RF)
technology, wireless LANs transmit and receive data over the air,
minimizing the need for wired connections.

**Benefits of the wireless LAN**

In the NIH network environment, using wireless LANs to supplement the
wired network offers advantages in productivity, convenience, and cost.
Wireless users can access shared information without looking for a place
to plug in, and network managers can set up or build up networks without
installing or moving wires. Doctors/scientists and nurses in hospitals
are more productive because notebook computers with wireless LAN
capability deliver patient information instantly. Senior executives or
network managers in meetings can make quicker decisions because they
have real-time information at their fingertips.

## Purpose 

This document contains the standard operating procedures for setting up
wireless LAN client access for NIH staff.

## Scope

This document provides procedures for the following tasks:

-   Installing the wireless client adapter driver

-   Installing the Aironet Client Utility (ACU) for Windows

-   Configuring the Aironet Client Utility (ACU)

## Audience

These procedures are intended for:

-   Technical Assistance and Support Center (TASC)

-   Deskside Support staff

-   Network Operations Center (NOC)

-   Network Operations Section staff

-   LAN Administrators

## Wireless Authentication Overview

In the NIH wireless LAN environment the Cisco Client Adapter and
Utility, Access Point, and RADIUS server are configured to use the Cisco
Light Extensible Authentication Protocol (LEAP) option. The proprietary
LEAP option encrypts data transmissions using dynamically generated
Wired Equivalent Privacy (WEP) keys, which are exchanged between access
points and Cisco Aironet 802.11b wireless LAN clients. LEAP causes the
network software and firmware to trigger server-based authentication
using the LEAP-enabled Remote Authentication Dial-In User Service
(RADIUS) server.

When the user turns on the computer, the wireless adapter tries to
associate with the AP. The AP blocks the wireless adapter request until
the user logs in with username and password. The login information is
sent to the AP in a one-way hash using MS-CHAP. The AP helps the
wireless adapter and the RADIUS server to perform mutual authentication
and derive a dynamic unicast WEP key by sending the information from the
wireless adapter to the RADIUS server (it is still hashed and encrypted
at this point). The RADIUS server checks the information against its
database. If it is in the RADIUS server database the server sends a
dynamic WEP key to the client, using MS-CHAP one‑way hash. The client
decrypts the transmission and uses the WEP key for the allocated amount
of time.

The NIH wireless network uses an external database for authentication.
The client username and password is not in the RADIUS server---the
RADIUS server points to a domain using a Windows server. The RADIUS
server then sends a request to the NT domain, and NT okays or denies the
request, sending the information in a one-way hash. This method supports
single logon requirements: the user's wireless LAN password and NT
domain password are the same.

The Macintosh client uses software and firmware on an installed Cisco
card to encrypt the information. This way it can use MS-CHAP because it
is done in the Cisco software.

# Troubleshooting

This section provides information to help solve problems relating to
wireless LAN access.

## System Requirements

This section lists the basic system requirements for wireless LAN
access.

### PC System

PC system requirements are:

-   Windows 95, 98, NT, 2000, XP, or Me

-   486 (33-MHz) processor

-   16 MB RAM

-   39 MB free disk space

-   VGA+ compatible display adapter

-   256 colors or at least 16 shades of gray

-   640 x 480 resolution monitor

-   CD-ROM drive

### Macintosh System

Macintosh system requirements are:

-   Mac OS 9.x (Cisco PCMCIA) or above (Mac OS X version 10.1; AirPort
    adapter will work with Cisco AP for the LEAP option)

-   Power PC processor

## EAP Authentication Requires Matching 802.1x Protocol Drafts

We currently use Network-EAP authentication on the NIH wireless network.
Therefore, the client devices and access points must use the same 802.1x
protocol draft. For example, since we are using 802.1x Draft 10 for the
Access Points, the radio firmware on the client devices (PCMCIA) that
will associate with an access point should be 4.25.30. The following
table lists firmware versions for Cisco Aironet products and the draft
with which they comply.

## Troubleshooting steps

This section explains the steps for troubleshooting the wireless client.

### Users are unable to authenticate through wireless LAN

When users are unable to authenticate through the wireless LAN, do the
following:

1.  Verify that users are using Cisco Aironet client adapter 340 series
    or 350 (model: AIR-PCM352). **Note:** the 340/350 series has two
    models. The AIR‑PCM341/351 does not support LEAP. The AIR-PCM342/352
    does.

2.  Verify that users are using adapter driver 8.2.3, radio firmware
    4.25.30, and ACU Version 5.01.x or later. Do the following to verify
    adapter driver, radio firmware, and ACU version.

**Note:** If the client is using the Cisco integrated Mini PCI wireless
adapter, the adapter driver should be 3.4.9 and the radio firmware
should be 5.00.03.

a.  Double click the Aironet Client Utility (ACU) icon from the desktop
    to bring up the ACU utility. You can verify the version of ACU from
    the **Aironet Client Utility** window (Figure 34).
