Déconexion Wifi intempestive
Bonjour,
J'ai un petit problème assez énervant, quand je suis sur internet en wifi, la connexion se coupe au bout d'un moment, mais pourtant l'icone dans la barre des tâches indique toujours qu'il capte le signal...
Ce que je fais quand c'est déconnecté, je clique droit sur l'icone => je décoche activer la connexion wifi, j'obtiens l'icone avec les deux petits ordi, puis je la réactive, et ça remarche.. mais c'est relou !
Surtout que ça ne le fait pas tout le temps, je peux par exemple laisser mon ordi a telecharger une après midi sans qu'il ne se coupe, mais dès que je surf sur le net ça va se couper...
donc si quelqu'un peut m'aider a résoudre ce problème, voici le résultat des commande indiquée dans le post épinglé pour ce genre de problèmes :
