problème de connection backtrack 5

Bonjour,

Sous backtrack 5 R3 gnome 64 en live cd,
j'ai beau chercher des solutions partout, impossible de me connecter à ma box.

D'abord impossible d'obtenir une adresse ip, avec wicd network manager j'ai l'erreur "Connection Failed: Unable to Get IP Address". J'ai fait un tcpdump si ça peut aider à voir se qui se passe :

[email protected]:~# tcpdump -i wlan0

Je comprend pas d'ou vient le problème parce que je me connecte sans problème sous windows7 et ubuntu et que sous backtrack5 je peut pas me connecter à ma box (j'ai oublier de préciser que c'est une neufbox) mais j'arrive à me connecter au hotspot freewifi.

ps : ma carte wifi  : Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter

merci
