Bonjour à tous .
Je suis un utilisateur d' Ubuntu depuis quelques années : j' étais sur une version 32bits et je viens de migrer récemment en 64 bits .
Depuis ce changement ma connexion wifi se coupe et je suis obligé de redémarrer à chaque fois pour la récupérer .
J' ai cherché un bon bout de temps pour trouver une solution mais rien ne marche .
Voici la copie de mon fichier "wificheck.log"
