[Résolu] ThinkPad X220 : Activer le réseau sans fil

Bonjour,

Je viens d'installer Ubuntu 14.10 sur mon laptop Lenovo ThinkPad X220, et le wifi ne marche pas.

J'ai tenté de le fixer dans Paramètres>>Réseau, mais en cliquant le bouton en haut à droite, mais ça se clique pas ! Qu'est-ce qui se passe ?

Voici des informations :

Quelques sources :

1. Des infos à partir de la Documentation ubuntu-fr

2. Page web du pilote
- J'en parle ci-dessous.

J'ai suivi le tutoriel B sur cette page

En suivant cet étape...

...je pensais que j'avais le pilote incorrect à cause de ce « driver=rtl8192ce », mais après avoir téléchargé le pilote mentionné ci-dessus et avoir lu le fichier README, il semble que et le rtl8188ce et le rtl8192 utilisent le même pilote.

Merci en avance !

Après deux jours, j'ai en partie résolu le problème...en actionnant le commutateur...
MAIS je ne peux pas connecter à un réseau sans fil. Je peux voir le réseau, mais ça marche pas. Encore une fois, voici des informations :

Re : [Résolu] ThinkPad X220 : Activer le réseau sans fil

Après la dernière mise à jour faite grâce à la Gestionnaire de mises à jour, tout semble à fonctionner parfaitement.
