Bonjour à tous ! Joyeux Noël
Suite à de nombreux problèmes avec Windows, j'ai décidé de définitivement dire adieu à Bill Gates ! J'ai réinstallé Ubuntu sur tout le système, tout s'est très bien passé, jusqu'au moment où il a fallu que je me connecte à Internet ...
Après de nombreuses recherches ici même, et sur google, je n'ai rien trouvé qui pût me guider vers une connexion ... En fait quand je clique sur le network manager, avec l'espèce de petite antenne, c'est écrit en gris clair : "device not ready". D'habitude, j'ai la liste de toutes les boxes de l'immeuble, et là rien ...
Je ne sais pas quoi faire, aidez-moi s'il vous plaît à retrouver ma neufbox ...
Bonne journée,
Amicalement.

Merci pour votre aide ...

Salut,

as-tu cherché la référence de ton chipset wifi sur Ubuntu-fr.org ? Parce que cette page semble intéressante...

Oui j'ai fait ça, ma wifi détecte maintenant les réseaux sans fil, j'arrive même à me connecter sur ma neufbox, mais je ne peux pas accéder à Internet oO (ça fait comme si je n'avais pas de connexion ...)

As'tu la gestion des réseaux??? (clic droit sur le bureau >executer >gestion des réseaux)
Tu ouvre l'Add network connection - Gestion du réseau de ta connection neuf et tu entre la clef WEP/WPA puis coche "Connect auomatically"

Vérifie aussi les autres paramètres

En fait c'était tout simple !! Il suffisait d'entrer dans les pilotes des périphériques, et de mettre à jour tout ça !
Merci à vous
