Bonjour,
Depuis quelques année, je tourne Ubuntu sur mon Acer Aspire 2920Z. Mais je ne n'y touche pas trop
Depuis que j'ai téléchargé les dernières mises à jour ce w-e, l'icone du wi-fi a disparu, et je n'ai plus aucune connexion réseau.
J'ai parcouru la doc et différents post mais je ne trouve pas de solution
voici les résultats des différentes commandes :
