Bonjour,
Après installation de ubuntu 14.04.3, je n'ai pas de connexion, et aprés avoir consulté de nombreux sujets sur ce problème, je ne l'ai pas resolu, d'autant que je n'ai pas de connexion filiaire non plus (pas de port ethernet). j'ai tenté des methodes manuelles pour mettre à jour le pilote proprietaire et l'activer, mais rien n'y fait). Bien qu'habitué d'ubuntu depuis une dizaine d'années, je ne maitrise que trés peu la ligne de commande et autres manip que je comprends pas bien..
A noter que la connexion fonctionne en bootant sur la liveUSB (c'est de là que je vous écrit) et en activant le pilote propriétaire. Sur l'OS installé, quand je coche utiliser broadcom 802.11 Linux STA et appliquer changement, la case se decoche et se remet sur ""ne pas utiliser ce pilote". Je n'arrive pas à savoir si cela vient du pilote, d'un module non installé et/ou si la carte rréseau est reconnue et active.
Le probleme c'est qu'il m'est compliqué de poster les réponses aux commandes demandées pour vous exposer le probleme, cependant je vous donne les réponses que j'obtient en bootant sur la live usb :
