(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 red X
and show an unavailable connection even though a wireless connection exists. This condition is caused
by a conflict between ADU and Windows XP’s wireless network settings. Simply ignore the Windows
icon and use the ASTU icon to check the status of your client adapter’s wireless connection.
