Clef wifi reconu, mais pas de connection

Bonjour,
J'ai installé depuis peu Linux fedora core 6.
J'aimerai établir une connection internet par wifi avec ma Livebox sagem (j'ai une clé wifi XG-750N).
J'ai donc installer ndiswrapper,j'ai tout configurer, mais n'arive toujour pa à me connecter.
Ma clé est bien installer.

voici quelques commande que j'ai taper dans le terminal:

[root@localhost Nicolas]# /sbin/iwconfig
