PB connexion avec intelPRO wireless 2200BG

bonjour,
j'ai un portable SONY VAIO VGN-FS115M et j'ai installé mandriva 2006 sans problème.

J'ai configurer ma connexion internet en ethernet avec une iP en dur car ma freebox est en mode routeur.

J'ai ensuite voulu passer en wifi et j'ai procedé à la configuration de la carte intel pro wireless 2200 BG grace au centre de controle. Tout se passe bien la carte setrouve sur le device eth2 et la connexion est activé, j'ai paramétrer le firewall avec le CDC sur la carte wifi device eth2 . Ensuite j'ai essayé de ma connecter via firefox mais la connexion ne se fait pas :(

Pour vous aider voici quelques infos :

Je precise que je n'ai pas recompiler le noyau, je suis sur un noyau 2.6.12-12mdk

merci d'avance pour votre aide
