Deconnexion intempestive WIFI Xubuntu 14.04
Bonjour à toustes,
Je poste ici car j'ai un problème récurent de déconnexion wifi intempestif sur un portable toshiba C670. Tous le 1/4d'h environ.
Machine d'une amie.
Le problème est lié au changement de kernel, lors de la mise à niveau vers xubuntu 14.04.
Avant sous 13.10 cela fonctionnait correctement, désormais il faut fréquemment désactiver puis réactiver le wifi sur le portable pour qu'il "revoie" la connexion. La connexion filaire est fonctionnelle, le wifi de la box aussi.
Si je comprend bien il y a un problème de gestion de l'alimentation/veille du composant wifi du portable. Je n'ai pas trouvé de solution (à ma portée) à ce problème dans les fils de discussion relatifs à des problèmes similaires et mes posts sont restés sans réponse.
Merci pour votre aide...
Je suis assez novice sois dit en passant.
Voici le résultat de wificheck, si cela peut aider.
