[Résolu] Problème de wifi Acer Aspire 7720
Bonjour il y a plusieurs mois je n'arrivais pas a configurer mon wifi sur mon ancien Packard Bell avec une clé Wifi Belkin, malgrés l'aide de plusieurs forumistes içi sans succes. Ce PC a rendu l'ame, j'ai donc acheter un nouveau PC Acer Aspire 7720 en me disant que sa marcherai direct quand j'installerais Ubuntu, et bien NOOON 
. J'appelle donc une nouvelle fois a votre aide en éspérant que cette fois c'est la bonne.
