wifi tres lent sous ubuntu 9.04 !!! [resolu]

bonjours a tous.
j'ai un probleme avec mon wifi .
la connection est vraiement tres lente (3 à 4 min pour afficher google avec l'ordinateur à 30 cm du routeur).
j'utilise une carte Intel Corporation PRO/Wireless 3945ABG. le driver utilisé est le iwl3945.

voici les resultats des commandes demancés ici.
