[Linux Ubuntu 11.04] Pb session avec le Wifi

Bonjour,

J'ai installé Linux Ubuntu 11.04 (Natty) sur le PC Portable eMachines-E625.
--> eMachine E625 : https://www.emachines.com/selection/

Tout s'est correctement installé, et un pilote propriétaire m'a été conseillé pour le Wi-Fi.

Je rencontre un problème avec le pc portable eMachine E625 en ethernet eth0.

--> Le problème quand je suis en connexion par Wi-fi ?
Lorsque je branche le port ethernet : Le menu avec la raccourci à droite apparait ainsi que l'horloge et le réseau .

Lorsque j'exécute le wifi au démarrage, ça plante le système, bizarre

--> le wifi est en eth1 ??? bizarre, habituellement il devrait être en wlan
