Ubuntu 15.04 perd le signal

Bonjour à tous,
J'ai ce bug depuis Ubuntu 14.04. Je suis passé à Ubuntu 15.04 en espérent qu'il soit résolu, mais non. Je me tourne vers vous pour vous demander quel est le problème.

Si l'ordinateur est allumé depuis un moment, il va perdre le signal. Je ne désactive pas le wifi, il est bel et bien activé. Mais pour une raison inconnue, Ubuntu se déconnecte du réseau alors que mon portable reste connecté. J'ai l'impression que ça vient de ma carte réseau, car quand je branche un dongle Wifi sur mon ordinateur, Ubuntu se connecte à nouveau à la Wifi. J'aimerais donc savoir ce qu'il se passe avec ma carte réseau. Voici différents retour de commande (au moment où ces tests sont réalisés, ma carte réseau fonctionne sans problème)  :

Re : Ubuntu 15.04 perd le signal

A tout hasard, essaie un 

sudo apt-get install linux-firmware-nonfree

qui installera de petits pilotes qui peuvent parfois faire l'affaire.

Re : Ubuntu 15.04 perd le signal

Salut,
le linux-firmware-nonfree est déjà installé... Du coup, peut être le désinstaller ?
J'ai réussi à chopper le syslog avant le bug, je vous le met en entier ici :
