Chapter 8 Using the Aironet System Tray Utility (ASTU)

Overview of ASTU

Overview of ASTU

ASTU is an optional application that provides a small subset of the features available through ADU. Specifically, it enables you to access status information about your client adapter and perform basic tasks. ASTU is accessible from an icon in the Windows system tray, making it easily accessible and convenient to use. The ASTU icon appears only if a client adapter is installed in your computer and you did not disable ASTU during installation.

ASTU provides information and options in the following ways:

•In the appearance of the icon itself

•Through a tool tip window that appears when you hover the cursor over the icon

•Through a pop-up menu that appears when you right-click the icon

•Through a Connection Status window that appears when you double-click the icon

The ASTU Icon

The appearance of the ASTU icon indicates the connection status of your client adapter. ASTU reads the client adapter status and updates the icon every 1 to 5 seconds, depending on the value entered for the Refresh Interval on the Display Settings window. Table 8-1interprets the different appearances of the ASTU icon.

Note Windows 2000 and XP may display their own wireless network connection status icon in the system tray. Cisco recommends that you turn off the Windows icon and use the ASTU icon to monitor your wireless connection.

	infrastructure mode) or another client (in ad hoc mode) but the user is not EAP
	authenticated.
	A green icon indicates that the client adapter is associated to an access point (in
	infrastructure mode) or another client (in ad hoc mode), the user is authenticated if the
