Connexion Wifi sous Ubuntu

Bonjour,

Bonjour à tous,

Comme vous j'ai voulu me mettre à Ubuntu. Je l'ai installé sur un vieil ordi portable que j'avais rangé dans mon placard. Tout marche super bien, sauf le Wifi : lorsque je branche mon capteur Wifi, tout se fige sur l'ordinateur et je ne peux plus rien faire.

Mon opérateur est Neuf Télécom.

Voici le code correspondant à ma config :
