Mon wifi a disparu

lemirandais · Le 15/05/2009, à 18:57

Voila, avant la migration de le 8.10 a la 9.04, j'avais le wifi, et les 3 premieres semaines d'utilisation de la derniere version, le wifi fonctionnait. Maintenant, depuis 1 semaine, le wifi ne marche plus et donc n'est plus detectable par ubuntu. Pouvez vous m'aider?
Merci d'avance.
