Aucun adaptateur wifi trouvé (Ubuntu 18.04 LTS) [Résolu]
Bonjour,
J'ai un souci avec le wifi sur mon pc neuf (Asus TUF505DT) après avoir effectué un double boot Win10/Ubuntu : le wifi fonctionne parfaitement sous Windows, mais quand je veux rechercher un réseau sous Ubuntu, j'ai le message "Aucun adaptateur Wi-Fi trouvé".
J'ai suivi les conseils de plusieurs discussions sur les forums, mais rien ne marche...
Voici le résultat de :
wget -N -t 5 -T 10 https://framagit.org/cracolinux/wificheck/raw/master/wificheck && chmod +x wificheck && ./wificheckLe wificheck.log :

EDIT
Il a suffi de désactiver le secure-boot dans le BIOS pour avoir accès au wifi !
