Bonjour, je viens ici en quête de réponses car malgré pas mal de recherches rien n'y fait.
Je viens tout juste d'installer Ubuntu 18.04 LTS sur ma tablette Samsung Galaxy Book et la carte wifi n'existe pas. Il est impossible de l'utiliser, elle ne renvoie même pas d'état avec les commandes "iwconfig" et "sudo rfkill list".
J'ai cherché sur nombre de forums, et ici même sans jamais trouver de solution adéquate, ni même une personne dans le même cas que moi.
J'ai déjà réinstallé Ubuntu complètement de zéro mais rien n'y fait.
Voici donc la liste des commandes utiles selon
https://forum.ubuntu-fr.org/viewtopic.php?id=141183 :

Dans le résultat précédent, je vois d'ailleurs des composants d'Intel Xeon apparaître, ce qui m'a plutôt surpris.

Voici donc, en espérant que quelqu'un puisse m'aider. Merci par avance !
Je précise aussi que le système Linux est par conséquent complètement isolé d'internet, je ne peux pas connecter ma tablette par câble.
