[Résolu] déconnexion wifi au bout d'environ 20 minutes
Bonjour à vous,
je rencontre un petit problème avec un de mes ordis portables, celui ci, récemment mis sous ubuntu a un problème avec le wifi, tout marche nickel mais au bout d'un peu plus de 20 minutes la connexion coupe, l'ordinateur est un dell vostro v131, je ne sais pas si le problème n'est pas venu de la 15.04 lorsque j'avais essayé avant je n'avais pas eu de problème 
Sous windows 7 je n'avais jamais eu de problème avec le wifi non plus
voici les résultats des commandes :
