When connecting to a WEP secured network through the Connect to a network option, a user is not presented with the option to set the WEP key index. For networks using indices other than 1, this connection will fail.

Consider the following scenario:

• You are running a Windows Vista-based computer that includes Windows Media Center.
• You connect the computer to a secure wireless network.
• You install a non-English-language Input Method Editor (IME), and then you set this as the default IME.

When you start Windows Media Center and then try to join the secure wireless network, you are prompted to enter your Wired Equivalent Privacy (WEP) key. However, when you use either the keyboard or the remote control to enter any numeric character in the WEP box, the default IME setting is triggered. Therefore, you cannot continue entering the WEP, and you cannot connect to the secure wireless network.

On a Windows Vista-based computer, you change a wireless connection from a wireless access point that uses a valid Wired Equivalent Privacy (WEP) key to another wireless access point that uses an invalid WEP key. Then, the connection status may incorrectly display a “Connection Successful” message. However, the wireless connection is not connected.

In this scenario, either of the following messages should be displayed:

Connection Unsuccessful
Windows cannot connect to Wireless Access Point
