If you use a wireless connection to your network, it may take up to two minutes to connect to your network when you start your Microsoft Windows XP-based computer. This problem only occurs if you are using 802.1X authentication and you have unchecked the Authenticate as computer when computer information is available option. You may not experience this problem every time that you start your computer.
This problem occurs because a race condition is created when the ZeroConfig component and Extensible Authentication Protocol over Local Area Network (EAPOL) initialize. A race condition occurs when data propagates rapidly through a logic circuit far ahead of the clock signal that is intended to control its passage.
