[Résolu] Deconnexion intempestive Wifi / Ubuntu 11.10
Bonjour,
J'ai un problème avec ma connexion wifi depuis que j'ai installer Ubuntu 11.10 en dual-boot avec windows 7( sous windows tout fonctionne)
Ma connexion wifi fonctionne, j'ai accès à internet, mais je pert ma connexion de façon intempestive.ll ne doit pas s'agir d'une déconnexion Wifi puisque l'icône indique que c'est toujours connecté au réseau. Je dois alors me déconnecter puis me reconnecter au Wifi pour récupérer la connexion Internet.
Je me connecte grace à une freebox révolution. Clé WPA.

Re : [Résolu] Deconnexion intempestive Wifi / Ubuntu 11.10
salut
vas dans le menu Système → Administration → Pilotes de périphériques ou pilotes supplementaires
ubuntu te proposeras d'installé le driver broadcom-sta
blacklist les mauvais drivers brcmsmac et bcma
gksudo gedit /etc/modprobe.d/blacklist.confajoutes a la fin du fichier qui vient de s'ouvrir
blacklist bcma
blacklist brcmsmac
enregistres et quittes gedit
si le driver broadcom-sta est bien installé,redemarres le pc
