Bonjour à tous,
je me résous à demander de l'aide, car sinon mon pc va finir jeter par la fenêtre.
j'ai il y a maintenant bientôt un an acqui un PC portable avec Windows 8. Après une dur bataille, j'ai pu mettre ubuntu en dual boot à côté de celui-ci, mais voilà que je me confronte à un autre problème : à chaque reboot après l'installation, je n'ai plus de wifi, ma carte ne semble plus fonctionner, et c'est réellement frustrant. J'ai essayé avec Ubuntu 12.04 - 12.10 et 13.04, mais là je lâche l'affaire car je n'en peut plus. Les problèmes ont commencés après avril, avant tout allait bien sans aucun soucis, puis après une mise à jour catastrophe, impossible de trouver la source du problème. J'ai suivi de nombreux tuto, sans succès jusqu'à maintenant. L'installation actuelle date d'hier, il n'y a de tête que steam et bumblebee en logiciel tier installé.
EDIT : je n'arrive pas à trouver le sommeil quand un truc me dérange autant, en regardant un peu partout, quand je cherche à me connecter, après avoir repasser le pc en français, j'ai vu qu'il est écrit : réseau sans fil désactivé par commutateur matériel. Même en faisant désespérément FN + F2, cela ne change rien...
je vous insère le résultat des différentes commandes, en espérant que vous puissiez m'aider :
