Connexion réseaux WI-FI impossible

ma_th_ia_ss_

Bonjour à tous !
Je vous contacte car depuis quelques jours, Ubuntu commence à ne plus vouloir me connecter en WI-FI, je suis actuellement par Ethernet !
Au début j'avais un message d'erreur lors de la connexion à un réseau, mais maintenant, j'ai comme l'impression que ma carte réseau n'est pas reconnue, car son nom n'apparaît par exemple pas dans le menu en haut à droite de l'écran.
De plus, lorsque je me rends dans la liste des réseaux disponibles, aucun réseau n'est détecté, et pourtant tous mes autres appareils sont connectés et voient plusieurs modems !
-------
J'ai vraiment cherché de partout pour trouver une solution, mais j'ai l'impression de juste m'enfoncer de plus en plus dans les ennuis...
Quelqu'un pourrait-il m'aider ?
Je vous remercie par avance ! 🙂

Bonjour,

Peux tu donner les informations ci-dessous :

xubu1957 a écrit Il faut fournir, en te servant du Retour utilisable de commande, un [doc]wificheck[/doc] rassemblant les informations > Configuration wifi, avec la clé wifi branchée.

Étape 2: Il ne reste plus qu'à copier le contenu du fichier wificheck.log (et non le fichier wificheck qui est le programme qui a généré le fichier wificheck.log) situé dans le dossier personnel et le copier sur le forum.

cqfd93 a écritAstuce pour copier / coller sans erreur :

triple clic gauche pour sélectionner et copier une ligne entière

clic molette pour coller dans le terminal

Après, on attendra le passage de xubu

Bonjour,

@Nico

J'envoyais un message aux modos, pour passer la discussion en section WiFi.

Merci à vous deux !
Mon PC est d'occasion mais s'approche justement des 2012 il me semble.
Après désactivaiton SecureBoot, la carte réseau intégrée est à nouveau reconnue et j'ai pu me connecter avec !
------------
Je suis néanmoins entrain de mettre à jour ma clé WI-FI justement, je me permets de rester avec vous en vous tenant au courant dès que c'est finit pour la clé après reboot !

Alors après désactivation SecureBoot et mise à jour de ma carte WI-FI, le problème est enfin résolu pour les deux cartes !
Sujet résolu ! un grand merci à vous deux !

(Message envoyé depuis clé WI-FI 😉 )
