Bonjour,
J'ai plusieurs ordinateurs portables dont 2 Toshiba satellite. Sur les autres, aucun problème, mais sur les 2 toshiba, lorsqu'on les allume, tout fonctionne très bien pendant quelques minutes (assez variable, de 1 à 15 minutes environ je dirais) puis d'un seul coup, la connection internet est coupée : plus moyen de charger une page internet, de faire des mises à jour ... Pourtant, le logo de la wifi a toutes ses barres et quand je vais dans paramètres, réseau, tout me semble normal, avec en particulier un signal de force : excellent.
J'ai cherché dans le forum mais n'ai rien trouvé qui correspondait à mon cas.
Je vous envoie, comme demandé, le retour des commandes :
