[resolu] Plus de wifi depuis mise a jour (ubuntu 12.04 LTS)

Yahia-c · Le 02/03/2014, à 00:48

Bonjour,

ma wifi marchait très bien jusqu’à ce que je fasse la mise a jour dans le gestionnaire des taches
du coup je suis obligé de passé par câble ethernet et c'est pas très pratique.

Merci de m'aider

Bonjour,

bip bip ...j'trouve plus ma boule de cristal pour deviner ta configuration

Direction la section "Configuration wifi" de ce forum, puis lit le post "A lire avant de poster !!!"

bizarre ton probleme. Quand tu clic droit sur l'icone network manager, le réseau "sans-fil" est bien activé (=avec une petit "coche" devant) ?
Donne le retour de

est-tu en double boot "windows/ ubuntu" ? si oui, quel version de windows ?
