Problème avec internet et le wpa avec Wubi

Bonjour,

J'ai installé Ubuntu sur mon PC avec l'utilitaire Wubi, tout semble s'être bien déroulé mais je n'arrive pas à aller sur internet.

J'ai donc un peu cherché (je ne connais pas du tout linux) et j'ai suivi ce tutoriel : http://www.commentcamarche.net/faq/sujet 11210 configurer le wifi sous linux

Mais ça ne marche toujours pas, donc comme c'est suggéré je poste un message dans ce forum avec les résultats de quelques commandes, merci d'avance de m'aider.
