Activation pilotes wifi ?

Bonjour à tous.

Je viens vous demander de l'aide pour un problème assez gênant, mon driver wifi (il me semble) ne fonctionne pas mais est pourtant reconnu par une certaine commande.

Explications : Tout marchait bien, j'ai voulu changer mon disque dur en le remplaçant par un disque dur sous windows sans succès donc  j'ai remis l'ancien (sous ubuntu) et là d'un coup la wifi ne marchait plus.

Même en cochant "Activer le réseau sans fil" rien ne se passe
J'ai une touche avec un voyant qui me servait autrefois a activer/désactiver la wifi mais elle ne marche plus.

Pour info: - J'ai fait mes recherches sans succès, étant un newbie, je fais mes post quand je suis vraiment dans la m*rde.
- Ubuntu 12.04

Re : Activation pilotes wifi ?

Bonjour,
   Le résultat de la dernière commande semble indiquer que ta carte Wi-Fi est désactivée dans le BIOS ou l'UEFI. Il faudrait donc faire un tour dedans pour vérifier que ce n'est pas désactivé.

Pour éviter de perdre vos données, utilisez des formats ouverts (cf. www.formats-ouverts.org).
Regardez l'utilisation moyenne de votre processeur et pensez à BOINC.

Bonjour.

Pourrais-tu me donner les étapes à faire pour vérifier cela ?

Re : Activation pilotes wifi ?

Problème résolu à l'instant grâce à Julius22 qui  m'a mis sur la voie.

Je suis allé trifouillé mon BIOS, j'ai changé les paramètres d'amorçage sans succès puis j'ai remis les configurations par défaut et pouf, magie.

Re : Activation pilotes wifi ?

Pense à passer ton sujet en « résolu », alors, s'il te plait.
