Perte d'internet mais pas du wifi suite à une mise à jour de 12.04
Bonjour,
Suite à une mise à jour il y a une semaine environ d'ubuntu 12.04 (après une longue période de non utilisation), je me suis aperçu aujourd'hui en réutilisant ce pc pour la 1ère fois depuis cette mise à jour que je n'ai plus de connexion internet alors que ma clé usb wifi détecte bien mon réseau wifi.
Je vous communique les données telles que demandé en début de forum.
Merci pour votre aide

eth0 no wireless extensions. Non, je n'ai pas essayé d'autres pilotes car tout simplement je n'ai plus d'accès au net. Mon PC est dans une pièce très distante de la box et cela ne serait vraiment pas une sinécure de devoir tout débrancher le pc pour le rapprocher de la box 
En outre, tout fonctionnait normalement en 12.04 avant cette dernière mise à jour...
