[Résolu] Wifi ne s'affiche plus après désactivation

Bonjour à tous,

J'utilise Ubuntu depuis un an déjà (16.04) sur un dell Latitude. Jusque là le wifi marchait bien. Il y a quelques jours, j'ai désactive le wifi en cliquant dans le menu déroulant en haut à droite du bureau où les connexions apparaissent (car j'utilise un cable éthernet). Après avoir mis en veille mon ordinateur (fermé le clapet), l'option wifi (que j'avais désactivé) a disparu, et n'est pas réapparue depuis. Je ne me souviens pas si ça à coïncidé avec une mise à jour récemment. L'option wifi n'apparaît plus dans le network manager. Dans "edit connections", il y a encore la mémoire des anciennes connections WIFI avec les paramètres. Je ne peux donc plus réactiver mon wifi !

Infos rapides:
- carte wifi:  Intel Corp wireless 8265/8275 (rev 78)
- dans additional drivers, il est écrit que j'utilise: oem-wifi-intel-iwlwifi-lp1757035-4.4-dkms

J'ai pas mal fouillé les posts, mais vu que je m'y connais très peu, j'ai du mal à comprendre exactement  à quel niveau se situe mon problème... J'ai effectué deux manips (sans succès):
1) J'ai désactivé le "secure boot" dans le BIOS
2) J'ai mis à jour le noyau (j'espère)  en lançant "apt-get dist-upgrade".

Un des diagnostics que j'ai fait et où il m'a semblé détecter un problème est dans "lshw", où il y a écrit que la carte wifi est "unclaimed". Mais je n'arrive pas à comprendre ce que ça veut dire. "Unclaimed" par qui? Par ubuntu? Est-ce qu'il me manque un driver?

Je suis vraiment perdu, merci d'avance de votre aide !

Voici les sorties du script wifi et des commandes demandées dans le post "à lire avant de poster" smile :

Re : [Résolu] Wifi ne s'affiche plus après désactivation

Merci c'est bon!

Si possible j'ai deux questions par contre, histoire de comprendre un peu mieux ce qui est arrivé (et aussi pour les futurs problèmes):
1) Quel est le diagnostic où il y a eu une anomalie, dans la liste des commandes que j'ai lancées?
2) Si c'est au niveau du "UNCLAIMED", qu'est-ce que ça signifie? Je ne comprends pas à quel niveau de la chaîne il y a un problème. Est-ce que ça veut dire que la carte wifi est reconnue par l'ordi, mais aucun Driver ne la voit?

Re : [Résolu] Wifi ne s'affiche plus après désactivation

Le pilote wifi ne ressort plus, on devrait voir :

Network controller [0280]: Intel Corporation Wireless 8265 / 8275 [8086:24fd] (rev 78)
	Subsystem: Intel Corporation Wireless 8265 / 8275 [8086:8110]
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

Et dans le lsmod, on ne voit pas de ligne pour la gestion du wifi :
