Bonjour,
je m'appelle Sam et je viens de switcher sur Ubuntu 18.
Tout c'est bien passé excepté le wifi, lorsque je vais dans les paramètres wifi j'ai le message : aucun adaptateur wifi trouvé.
Voici les différentes étapes réalisées selon les règles du forum, je vous remercie pour votre aide car je suis perdu.
