Bonjour,
Comme beaucoup, j'ai subi il y a 2 jours le désagrément de voir mes connexions Internet disparaître.
Suite aux différents post trouvés sur le forum, j'ai réussi à me reconnecter en filaire puis à faire les mises à jour proposées.
J'ai ainsi pu réinstaller network-manager et reparamétrer une connexion filaire.
Hélas, je suis incapable de recréer ma connexion wi-fi car dans l'impossibilité de trouver l'adresse MAC de la carte.
J'ai lancé le script Wificheck proposé par le forum et obtenu le fichier Wificheck.log que je fournis ci dessous.
Si quelqu'un pouvait m'aider, ce serait cool, car cette connexion Wifi a toujours très bien fonctionné.
Voila le résultat du log
