Bonjour !
Je suis sous Ubuntu 15.04 32 bits en dual-boot avec Windows 7 pro. Mon wi-fi fonctionnait très bien avec ma live-box. Il me semble qu'elle avait été détectée automatiquement et que je n'avais rien eu à faire de spécial. Je viens de changer de live-box. Et quand je clique sur l'icone wi-fi dans le coin haut droite, on ne me propose aucune connexion. Il est écrit "réseau wi-fi déconnecté" en gris clair, et "activer le réseau" et "activer le réseau wi-fi" sont cochés. Pouvez-vous m'aider ? Voici les retours de commandes demandés :
