• Linux Software for the Authentication: wpa_supplicant. It is a WPA Supplicant with support for WPA and WPA2 (IEEE 802.11i/RSN)

• A good Networkanager GUI and front-end of wpa_supplicant is NetworKManager. A list of Supported Wireless Cards & Drivers is also available. A wiki about NetworkManager can be found in section Using NetworkManager
