Maintenant mon problème:
Le wifi marchait parfaitement jusqu'à la dernière mise à jour lancée hier ( je n'en avait pas fait depuis un ou deux mois ), je ne sais pas précisément ce qui a été installé.
Depuis, tous les réseaux wifi sont toujours bien détectés, mais je ne parviens plus à m'y connecter - j'y suis parvenue une fois après avoir booté sur windows ( qui se connecte sans problèmes - je me demandais si le pb venait de ma carte wifi ), mais cela n'est pas reproductible. Depuis plus rien. Reboots et désactivation/réactivation matériels de la carte wifi sont inutiles.
Vous avez une idée de ce qui peut m'arriver ?
