[Résolu]Problème wifi: Acer Aspire 5020
Bonjours.
J'ai installé la version d'Ubuntu 8.10 la semaine passée, le wifi a fonctionné du premier coup sans rien bidouiller. Je ne sais pas ce qu'il c'est passé mais maintenant il ne fonctionne plus: la led wifi sur le portable n'est plus allumée et je n'arrive plus à voir les réseaux sans fils disponibles. Les drivers sont toujours installés.
Quelques infos:
