NicoApi73 a écritBonsoir,
Ouvre un fil spécifique pour ton cas STP. Et il faudrait que tu donnes tout ce que tu as fait avec les retours, pour voir s'il n'y a pas des messages d'erreurs...
Je crois que quelqu'un s'en est occupé. Merci !
J'ai suivi la procédure décrite dans ce sujet
https://forum.ubuntu-fr.org/viewtopic.php?id=2034232 et je n'ai pas eu de message d'erreur.
sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
chmod +x dkms-install.sh
chmod +x dkms-remove.sh
sudo ./dkms-install.sh
Et j'ai redémarré le pc en désactivant le secure boot.
