J'utilise ubuntu 15.04 vif, je suis connecté au wifi mais quand j'ouvre Firefox, il est dit "Serveur non trouvé", j'ouvre Software Updater, il a dit Échec du téléchargement, essentiellement pas d'accès à Internet. Mais j'ai déjà utilisé ubuntu 14 et je pouvais utiliser le wifi normalement sans aucune erreur. Mes fenêtres et mes téléphones fonctionnent également sans aucune erreur. J'ai nettoyé plusieurs fois et j'ai le même problème.
Voici quelques informations sur ma situation:
Mon appareil wifi est: Huawei HG8045A
