Re : perte du wifi
bonjour
il y a une petite erreur dans ton fichier interfaces, on va corriger avec cette commande :
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
reboot et reteste le wifi uniquement avec network-manager (icone en haut a droite a coté de l'heure)

depuis Dapper Drake ! Ça rajeunit pas ^^^).

Re : perte du wifi
bizarre....ma ligne de commande aurait remis le fichier "/etc/network/interfaces" au propre afin que network-manager puisse gerer tes connexion (avec ou sans-fil) correctement

Re : perte du wifi
A priori, si le cable est branché, il se connecte avec.
Par contre je ne sais pas pourquoi çà marche
Merci quand même
