[resolu]Probleme de connection wifi avec Lenovo 3000C200
Bonjour,
J'ai installer Ubuntu sur un portable Lenovo 3000C2OO suite à changement du disque dur pour découvrir l'univers Linux et voir d'autres horizons. Je suis donc débutant. Tout ce passe bien sauf le wifi. J'ai bien la connexion filaire mais pas le wifi, la diode ne s'allume même pas.
Je suis sous wimax et j'utilise un routeur Netgear qui fonctionne très bien avec d'autres ordinateurs.
Voici les infos sur mon système :
