Coupure wifi récurrente
Bonjour,
Je découvre avec grand plaisir Linux et plus précisément Ubuntu 14.04, qui fonctionne parfaitement sur le pc de mon homme et mon portable. Ils sont connectés au même routeur que ce poste, qui, lui, perd la connexion wifi après quelques minutes, alors que Network-manager l'indique toujours connecté. Au départ, j'utilisais une clé Zyxel D2205. J'ai essayé un certain nombre de pistes trouvées lors de mes recherches, changement de pilotes, de clés de cryptage, ... qui n'ont strictement rien changé. Aussi j'en avais déduis une incompatibilité de la clé et j'en ai acheté une autre que l'on m'a certifiée compatible avec Linux. Une D-Link dwa-131. Grâce aux multiples tutoriels je suis parvenue à l'installer, mais les coupures persistaient. Après quelques tâtonnements j'ai choisi de tout reprendre au départ et ai réinstallé Linux. Résultat, j'en suis toujours au même point et ne sais plus trop quoi tenter.
Je vous remercie d'avance pour toute aide que vous saurez m'apporter.
