Salut, Je pense que ton problème serait mieux dans la rubrique support Debian, enfin tu aurais une meilleur visibilité. ---

# Suite à ce problème que je n’arrivais pas à résoudre, j’ai décidé d’installer debian 9.5 et la wifi ne marchait toujours pas pour autant. J’ai donc modifié la protection WAP (TKIP+AES) pour WAP (AES/CCMP) et cela fonctionne. Ah oui, je suis chez Free. Voilà, mon retour d’expérience. A mon grand regret, cela ne marche plus!!! C’est plus quoi faire. Merci de me donner la marche à suivre pour sortir de cette situation.
