[résolu]pas de wifi depuis installation14.04
Bonjour,
je viens d'installer Ubuntu 14.04 sur l'ordi 64bit d'une amie et je m'aperçois qu'il n'y a pas de wifi. Je suis très embêté évidemment. Voici la configuration:

Je remarque que iwconfig m'annonce qu'il n'y a pas de connexion sans fil. L'ordi utilise un pilote propriétaire : Broadcom 802.11 Linux STA depuis bcmwl-kernel-source. Visiblement, pas avec grand succès...
Si quelqu'un a une idée, d'avance merci.

Salut,
T'es tu inspiré de ça ?

Un peuple prêt à sacrifier un peu de liberté pour un peu de sécurité ne mérite ni l'une ni l'autre, et finit par perdre les deux.
