Bonjour,
Je suis sur la version 16.04 LTS d'Ubuntu
Depuis la dernière mise à jour du système (7 mars 2018), je ne parviens plus à me connecter aux réseaux wifi (j'ai essayé dans différents endroits), seule la connexion ethernet fonctionne.
Que puis-je faire pour résoudre ce problème ?
Merci !
Voici le résultat de mon wificheck:
