[Résolu] Pas d'activation WIFI

Entraide & Partage
1

Bonjour à tous, :wink:

Je n’ai plus de WIFI sur mon portable mais il fonctionne très bien en LIVE USB. :cool:
Je pense que j’ai désactivé la carte mais je n’arrive pas à la remettre en service.
Avant que je regarde les JO, il fonctionnait très bien mais pendant la séance du 100 m de Bolt :lol: j’avais un message pour me connecter
en WIFI alors que mon câble filaire était en service.
Pour ne plus avoir le message, j’ai donc désactivé en cochant une case sur le message.
Je pense que la panne date de cette période.
Merci de votre aide mais il n’y a pas urgence on se voit à Gouesnac’h.

Quelques infos supplémentaires.

Une bonne nouvelle : la carte physique et les modules logiciels sont présents et détectés (ath9k) ; une moins bonne, le Wifi est bloqué, ce qui est bien le problème.
Au passage, j’apprends quelques commandes que je ne connaissais pas.

Le problème est bien exposé, reste à trouver une solution.

Salut,

Merci pour la réponse et l’info pour le site internet. :slight_smile:
Le Wifi est désactivé dans les paramètres système et ne passe pas à 1.
Il me faut donc une ligne de commande linux . J’ai testé plusieurs mais pas de résultat. :frowning:
