aucun réseau wifi détecté sur hp envy 4

cronopio · Le 21/09/2015, à 13:30

Bonjour,

après une mise a jour, mon ordinateur ne détecte plus aucun réseau wifi...
il s'agit d'un hp envy 4 dv6, la touche f 12 qui sert de raccourci pour activer/désactiver le wifi est bloquée en position éteinte (lumière rouge) et impossible d'activer le wifi. Par contre j'arrive a me connecter avec un cable ethernet. quelqu'un peut-il m'aider?

voici le résultat des commandes dans le terminal :

bonjour,

connecte toi pc au net via le cable ethenet, puis :

sudo apt-get update && sudo apt-get install bcmwl-kernel-source

reboot et test si ton wifi est ok ou pas

cronopio · Le 22/09/2015, à 23:44

Bonsoir,

apres test de la commande cela ne fonctionne toujours pas...
la touche f12 active/désactive le bluetooth mais toujours aucun réseau sans fil détecté.

cronopio · Le 22/09/2015, à 23:54

Je pense qu'une partie du problème vient peut-être de là : quand je vais dans pilotes additionnels, le pilote réseau sans fil broadcom STA est marqué comme n'étant pas activé, et lorsque j'essaie de l'activer je recois le message d'échec suivant :
" Sorry, installation of this driver failed.
Please have a look at the log file for details: /var/log/jockey.log."
