Pas de connexion wifi sous Ubuntu 14.04.03

ebene

Bonjour,

Après une mise à jour de Ubuntu 14.04.02 --> 14.04.03 le wifi ne fonctionne plus.
Pouvez-vous m'aider à trouver ce qui bloque le fonctionnement du wifi?

Le paquet que tu veux installer se trouve dans les dépôts universe. Je ne les vois pas dans ton sources.list, il te faut donc les ajouter, faire un update et enfin installer cet installateur de pilote

Quand j'ajoute les dépôts via l'interface graphique le téléchargement ne fonctionne et m'affiche ce message: "Failed to download repository information Check your Internet connection".
J'ai refait la manipulation à plusieurs reprises mais toujours non OK. Voici le détail:

W:Failed to fetch http://fr.archive.ubuntu.com/ubuntu/[/url]/dists/trusty/universe/binary-i386/Packages  404  Not Found [IP: 91.189.91.23 80]
