[Résolu] Wifi actif mais perte de la connexion

Bonjour,

Voici une semaine jour pour jour que j'ai installé la dernière version de Ubuntu, et voilà une semaine que je rencontre une perte de connexion internet sans coupure du wifi.

J'ai lu le topic suivant traitant du même problème, mais j'ai toujours ces deconnexion (http://forum.ubuntu-fr.org/viewtopic.php?id=870901). Je m'en remets donc à vous étant un novice sur cette distribution.

Voici le résultat de iwconfig :
