Problème de Clé WIFI

Bonjour
Il y a peu de temps,j'ai retrouvé un vieux PC chez moi,que j'ai décidé de faire passer sous Xubuntu.L'installation s'est bien passée,et il ne restait plus qu'à me connecter à internet.Ne détectant pas mon réseau,je brancha donc une clé wifi (qui marchait très bien sous Windows).Celle-ci détecta le réseau et j'esseya de me connecter.Cependant,la connexion n'aboutissa pas,et je ne pus pas me connecter.
Que devrais-je faire?

EDIT: J'ai oublié de préciser ses informations

Re : Problème de Clé WIFI

Bonjour,

J'ai déjà eu ce problème plus d'une fois, mais je n'ai jamais compris d'où cela venait... Pour résoudre ce problème, je changeais de clé WIFI.
Essaye de te connecter manuellement au réseau :

Peux tu nous afficher le fichier /etc/network/interfaces ?

Tiens moi au courant
