Bonjour la Guilde,

J'ai un Dell XPS M1330 sous ubuntu 9.04 http://doc.ubuntu-fr.org/dell_xps_m1330

Suite à une mise à jour, la carte wifi ne se connecte plus à mon AP
wifi (cachée et WPA tkip)
la carte se connecte sans probleme a un reseau non crypté (ex FreeWifi)

Voilà les messages que j'ai lors de la tentative de connexion à mon AP :

tail -f /var/log/messages :

Problème de wpa ? J'ai (via synaptics) réinstallé wpasupplicant sans
succès, j'utilise NetworkManager.
Si quelqu'un à une idée, une piste je suis preneur.
