Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide
OL-4211-03
Chapter 1 Product Overview
Software Components
Software Components
The client adapters have two major software components: a driver and client utilities. These components
are installed together by running a single executable Install Wizard file that is available from Cisco.com.
This file can be run on Windows 2000 or XP and can be used only with CB21AG and PI21AG client
adapters.
Note Chapter 3 provides instructions on using the Install Wizard to install these software components.
Driver
The driver provides an interface between a computer’s operating system and the client adapter, thereby
enabling the operating system and the applications it runs to communicate with the adapter. The driver
must be installed before the adapter can be used.
Client Utilities
Two client utilities are available for use with the client adapters: Aironet Desktop Utility (ADU) and
Aironet System Tray Utility (ASTU). These utilities are optional applications that interact with the client
adapter’s radio to adjust settings and display information.
ADU enables you to create configuration profiles for your client adapter and perform user-level
diagnostics. Because ADU performs a variety of functions, it is documented by function throughout this
manual.
ASTU, which is accessible from an icon in the Windows system tray, provides a small subset of the
features available through ADU. Specifically, it enables you to view status information about your client
adapter and perform basic tasks. Chapter 8 provides detailed information and instructions on using
ASTU.
Note If your computer is running Windows XP, you can configure your client adapter through the Microsoft
Wireless Configuration Manager (or another third-party tool) instead of through ADU. Refer to
Appendix E for information. However, ADU is recommended for configuring the client adapter.
