Problème avec la carte wifi

Bonjour,

Je suis sous ubuntu 9.04. Ma connexion wifi marchait sans problème. Aujourd'hui le network-manager ne m'affiche plus aucun réseau au niveau de l'interface graphique !
Pourtant un scan de eth1 trouve le bon réseau.
iwlist eth1 scan
eth1      Scan completed :

Re : Problème avec la carte wifi

Purger le fichier /etc/network/interfaces.

I9ndispensable pour que N-M puisse prendre le controle des cartes
Auto lo en ligne de commande:

	sudo /etc/init.d/networking stop
	echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
	sudo /etc/init.d/networking restart
