Bonjour,
Je n'arrive plus à me connecter au Wifi, j'obtiens le message d'erreur "Echec de connexion - L’activation de la connexion réseau a échoué"
J'ai redémarré plusieurs fois, sans résultats.
Je ne suis pas très compétent techniquement, je ne fais pas de Terminal et tout ça.
J'ai fouillé le forum et a trouvé le conseil de faire un WIFICHECK.
Voici ci dessous ce qu'il y a dans le fichier wificheck.log
Merci d'avance pour votre aide !
