The current developement version 2.2.1 does not support a wireless connection to an SSID that provides a dynamic WEP key.
Cisco WISM controlled WiFi networks that are 802.1x enabled require the use of a dynamic WEP key.
This WEP key is unknown to the end user and so cannot use XSupplicant to connect to the SSID since XSupplicant demands the
user enter the WEP (40 HEX digits) key.
Microsoft built-in supplicants report 'WEP key is provided' but XSupplicant is not honouring this.
