Connexion wifi disparu

Hello,

Quelque chose de très bizarre vient de se passer, mon ubuntu marchait très bien, et d'un coup sans raison ne détecte plus la carte wifi, le wifi n'apparait plus, du coup je ne peux plus le connecter.
C'est un ubuntu 20.04, et je n'ai rien changé dans la config, en démarrant, le wifi avait disparu sans raison.

Il reste la possibilité de connecter au bluetooth ou en éthernet, mais pas en wifi

Quelqu'un a déjà vu ça?

Re : Connexion wifi disparu

Bonjour,

Il faut fournir, en te servant du Retour utilisable de commande, un wificheck rassemblant les informations > Configuration wifi.

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 écrit :

Astuce pour copier / coller sans erreur :

  • triple clic gauche pour sélectionner et copier une ligne entière

  • clic molette pour coller dans le terminal

Conseils pour les nouveaux demandeurs et pas qu'eux

Re : Connexion wifi disparu

Merci ! Je ne comprends pas, au bout du 6ème reboot, il a fini par réapparaître.

Je copie ici le wificheck au cas ou ça pourrait donner une idée à quelqu'un de pourquoi la connexion avait temporairemen disparu.
