New and Changed Information
Auto Profile Selection Enables Scan of Wireless Modes in Auto-Selected
Profiles
When you enable auto profile selection, the client adapter ignores the selected profile’s wireless mode
setting and scans the wireless modes specified by all the profilesin the auto profile selection list for an
available network. With this method, the client does not need to disassociate or to change the current
profile while looking for networks in other profiles.
ASTU Exit Option
The Exit option on the Aironet System Tray Utility (ASTU) pop-up menu closes both ASTU and ADU.
Windows Wireless Network Connection Icon Shows Unavailable Connection
(Windows XP Only)
If your computer is running Windows XP and you configured your client adapter using ADU, the
Windows Wireless Network Connection icon in the Windows system tray may be marked with a redX
and show an unavailableconnection even though a wireless connection exists. This condition is caused
bya conflict between ADU and Windows XP wireless network settings. Simply ignore the Windowsicon
and use the ASTU icon to check the status of your client adapter’s wireless connection.
