Impossible de se connecter à Wireless après avoir installé Ubuntu 12.10

J'utilise l'ordinateur portable Asus U56E et après avoir installé Ubuntu 12.10 avec Windows 8, je ne parviens pas à me connecter au réseau sans fil. J'essaie de résoudre ce problème depuis deux semaines et je n'ai pas pu le résoudre. Veuillez aider. Toute réponse serait appréciée.

Voici quelques résultats en ligne de commande.

Cela gardera la gestion de l'alimentation activée, mais cela limitera votre vitesse et votre portée wifi à des vitesses 802.11g.

  1. Exécutez les commandes suivantes

    Sudo rmmod iwlwifi
    Sudo modprobe iwlwifi 11n_disable=1
    
  2. Assurez-vous que la connectivité sans fil est restaurée. Pour rendre cette modification permanente, créez un nouveau fichier dans /etc/modprobe.d et y mettre ce qui suit:

    options iwlwifi 11n_disable=1
    
  3. Redémarrez pour voir les changements.
