EDIT : Solution ici : https://forum.ubuntu-fr.org/viewtopic.php?pid=21642310#p21642310
Après des années repassé sur windows pour cause de gaming intensif j'essaye de repasser du bon côté de la force. Mais Linux c'est pas comme le vélo et j'ai pour ainsi tout perdu 🙁
Bref, suite à l'achat d'un nouveau portable j'avais envisagé de repassé sur logiciel libre mais après avoir lancé le liveCD impossible d'activer le WiFi dessus qui repasse en grisé dés que je l'active sur l'IHM.
J'ai essayé de suivre les éléments de la doc ais jusque là rien n'a marché.
Voilà mes paramètres :
