Wifi qui tombe fréquement à 0%

Je ne sais pas si c'est pour une raison materiel ou logiciel, mais j'ai depuis peu des soucis avec mon Wifi qui perd totalement la connexion. Je suis obligé de cliquer sur l'icone de nm-applet et recliquer sur mon reseau. La connexion à mon réseau est à 0% mais elle reste connectée alors que le signal est trés correct dans la liste des réseaux sans fils.

Ce problème est toujours d'actualité et m'arrive fréquement.
