[Ubuntu] Retrouver et Decharger module wifi

Bonsoir,
dans un tuto pour installer une clef wifi sous Ubuntu et après avoir installer NDISWrapper (car pas de pilote libre dispo), on me demande de décharger le module par défaut gérant la wifi de mon ordinateur.
Mais voilà, je n'arrive pas à savoir lequel c'est... voici ce que me renvoi lsmod :
