1. Click one Wireless LAN connection from the tray icon

2. In the connection dialog window,

� a) Enter Security Key

� b) Double click the OK button

�

�

This problem occurs because the message handling for Wireless connection is not fast enough and causes overflow in the message queue.

�

�

Try reconnect to Wireless LAN again after the connection fails or Explorer automatically restarts. Trying in a place where there are less than 5 access points is more successful.
