Bonjour,
ça fait longtemps que je connais et consulte ce forum qui m'a résolu pas mal de problèmes, mais après 15 jours de tourner en rond je poste mon premier message en plein désespoir.
Voici mon souci : depuis deux bonnes semaines, après une mise à jours du système, je n'arrive pas à me connecter sur aucun réseau WIFI (même pas mes réseaux habituels : maison, école, chez mes parents, etc.). Mon ordinateur les détecte mais pas possible de s'y connecter, toujours échec.
Voici le contenu de mon wificheck :

J'espère que vous pourrez m'aider, parce que me connecter par voie filaire, c'est vraiment handicapant.
Merci d'avance !
