Aucun adaptateur wifi trouvé (Ubuntu 18.04 LTS)

Orient

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 && ./wificheck

Le wificheck.log :

EDIT

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

Bonjour,

Je vois trois pilotes :

Kernel modules: wl, 8821ce, rtl8821ce

et aucun pour :

cfg80211              704512  0

Donne :

bootctl

dkms status

et :

modinfo 8821ce

dmesg | grep  8821ce
