Pourquoi ne puis-je pas me connecter à un point d'accès sans fil Cisco?

Question

J'exécute un Lucid Netbook Remix sur mon Dell Inspiron 600m et je n'ai pas pu me connecter au réseau sans fil au Hacker Dojo à Mountain View hier. Il y avait beaucoup d'autres personnes sur le réseau - des boîtiers MS, Mac et Linux - mais mon ordinateur portable n'obtiendrait jamais d'adresse IP. Je peux me connecter à mon réseau domestique, qui est ouvert, et je n'ai jamais eu de problème de connexion au café, qui utilise le WPA. Le Hacker Dojo fonctionne WPA et nous avons vérifié le mot de passe un certain nombre de fois mais nous n'avons reçu aucun amour. Toutes les idées seraient grandement appréciées.
