Bonjour,
Je suis sur un Asus X405U avec une carte wifi RTL8822BE. Le problème est connu sur internet pour cette carte WIFI mais j'ai tout tenté sans succès. C'est comme ci la carte WIFI n'était pas détectée. Et les rares fois où elle l'est, il est noté "Aucun réseau disponible".
Je suis sous Ubuntu 16.04.
Quelques infos :
