Problème de connexion (Résolu)

el zibo · Le 07/05/2014, à 08:59

Bonjour,

Je constate suite à mon passage sur Ubuntu 14.04 des sauts de connexion Internet intempestifs. Brutalement, lorsque j'ai ouvert un programme lié à Internet : Chrome ou Steam, ma connexion wi-fi va brutalement s'arrêter. Dans ce cas, je la relance à nouveau puis ça fonctionne mais alors j'imagine qu'il y a plus simple pour régler ce problème.

Merci de vôtre aide.

Modèle PC : Toshiba Satellite C-50A
