[RESOLU] Wifi fonctionne qq min minutes puis plus malgré signal excell
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 :

Re : [RESOLU] Wifi fonctionne qq min minutes puis plus malgré signal excell
Merci beaucoup,
J'ai suivi le premier lien et pour le moment, il semble que cela fonctionne. Je n'ai aucune idée de ce qu'est rtl8723be, ni à quoi il sert, mais il semblait effectivement être le coupable.
Merci encore et bonne soirée.
