Connexion impossible

Bonjour,
Déjà je suis un peu nul en info, désolé. J'ai téléchargé et installé ubuntu 10.10. J'ai une clé wifi linksys wusb600N. Quand je suis sous linux, je vois bien  les nom des réseaux sans fil mais je n'arrive pas à m'y connecter alors que sous windows ca marche bien. Pouvez-vous m'aider, svp?
Voici les resultats des lignes de commandes

Re : Connexion impossible

Bonsoir,

Entrer ces commande dans un terminal :

sudo cp /etc/modprobe.d/blacklist.conf /etc/modprobe.d/blacklist.bak
echo 'blacklist rt2800usb' | sudo tee -a /etc/modprobe.d/blacklist.conf
echo 'blacklist rt2x00usb' | sudo tee -a /etc/modprobe.d/blacklist.conf
echo 'blacklist rt2x00lib' | sudo tee -a /etc/modprobe.d/blacklist.conf
echo 'blacklist rt2800pci' | sudo tee -a /etc/modprobe.d/blacklist.con

Rebooter pour que les modifications soient prises en compte, et dire au revoir aux deconnexions
