Problème Wifi après la mise à jour 14.10 vers 15.04
Après la mise à niveau d'Ubuntu 14.10 vers 15.04, j'ai un problème avec mon wifi. Je ne vois pas d'option avec le réseau sans fil dans la barre de menus.
Il y a un rapport du script sans fil-info wirelees-info :

Vous avez un mauvais noyau pour Ubuntu 15.04. Vous devez d'abord installer le noyau correct.
Téléchargez ces fichiers et copiez-les dans votre dossier d'accueil.
Puis exécutez dans le terminal
Sudo dpkg -i linux*.deb
Redémarrez.
Si votre connexion réseau est rétablie, exécutez
Sudo apt-get install linux-generic
pour installer le méta-package. Cela permettra les mises à jour du noyau.
