Wifi connecté mais qui ne marche pas
Bonjour à tous,
Comme pas mal de monde, avec la version précédente le wifi marchait nickel, et depuis Intrepid... plus rien.
Au début je n'arrivais même pas à me connecter au réseau, la fenêtre me demandant la clé wep se réaffichait sans cesse car le pc n'arrivait pas à se connecter au réseau.
J'ai passé la méthode de connexion en mode manuel en spécifiant une adresse IP statique et les infos ad hoc et là hop magie la connexion s'effectue !
Par contre pas moyen d'accéder à quoi que ce soit, ni Internet ni même le routeur lui-même...
C'est un portable Dell Inspiron 640m avec une carte Intel Pro WLAN 3945. Ci-dessous les infos requises :

Merci d'avance pour votre aide !
I know you believe you understand what you think I said, but I am not sure you realize that what you heard is not what I meant.
