Impossible d avoir une connexion wifi stable
Bonjour
Mon wifi se déconnecte tout le temps et je dois me reconnecter manuellement a chaque fois...
J ai essayé en lisant d autres discussions de paramétrer correctement mon wifi et ma Fritzbox(sunrise) mais étant novice je ne suis pas arrivé à résoudre mon problème ....qui est vraiment très pénible
Merci beaucoup de votre aide

Re : Impossible d avoir une connexion wifi stable
Salut !
J'ai eu le même problème avec ubuntu 12.304.
Pour vérifier si c'est le même problème que moi, fait un click droit sur l'icone wifi en haut à gauche de l'écran.
puis tu sélectionne Edit connections (c'est en anglais chez moi)
Dans la catégorie wifi, si tu as des connexions en double, efface les toutes (celles au nom de ta box).
et tu sors de cette fenêtre.
Ensuite tu fait un click gauche sur l'icone Wifi et tu sélectionne ta box. Tu mets le code et pour mou cela a fonctionné.
Jah bless
