§ 4.1 a écrit :

Si après Soft blocked vous avez un yes, alors le WIFI est bloqué de façon logicielle, par contre si vous avez un yes après Hard blocked c'est que votre WIFI est bloqué matériellement par un bouton dédié.
Pour activer les cartes Wi-Fi:
sudo rfkill unblock all

Tu actives comment le wifi sur cet ordi ?
Avec une combinaison de touches Fn + F n°? ou un interrupteur ?

J'avais besoin de mettre à jour leur pilote propriétaire par l'intermédiaire de l'outil Tableau de bord> Pilotes supplémentaires> Pilotes supplémentaires. Ensuite, après avoir essayé d'activer / désactiver le commutateur pour Wireless LAN via le BIOS, j'ai finalement basculé le commutateur matériel sur le côté droit de l'ordinateur portable: o Wireless fonctionne pour moi maintenant.

Pour le pilote additionnel, voir la Doc > gestionnaire_de_pilotes_proprietaires.
