oui,bonne idée,tu pourras l'essayer et on pourra t'aider a l'installer
mais il vaut mieux que tu nous dises quelles clé tu veux acheter et on te diras si elle est compatible ubuntu
tu auras 7 jours pour la rendre en magasin,si elle ne fonctionne pas bien

la reception du wifi n'est pas top,c'est soit l'eloignement par rapport a la box,un mur trop epais ou des perturbations electromagnetiques
essaye de changer de place a la box,la surelevée

essayes ces 2 commandes

sudo rmmod rt73usb
sudo modprobe rt73usb nohwcrypt=Y

si toujours rien
modifie le cryptage wifi dans les parametres de la box,choisi wpa tkip,sauvegarde les changements et il faudra peut etre redemarrer la box

Sur secteur, il n'y avait pas de problème.
Cela va dans le sens d'un problème au niveau de la gestion de l'énergie...

Depuis le version 12.10, je n'ai pas constaté le problème.

Quand je tape la première commande il me dit :
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan1 ; No such device.
(deuxième essai, le net fonctionnait)

J'avais essayé avant sans le net, il me disait rien. Mais internet ne revenait pas. J'ai redémarré.

Ubuntu 12.04 a été installé récemment sur mon pc et depuis j'ai remarqué des déconnections intempestives mais non régulières ainsi qu'une lenteur à l'affichage des pages du navigateur Firefox (j'ai l'impression d'être en 56k). Le pc me dit qu'il est connecté à la box (Bbox) mais je n'ai pas accès à internet. Est-ce un problème de configuration du pc ou un problème de box... Je ne suis pas (du tout) assez calée pour le savoir, pourriez vous m'aider svp?

Voici le résultat des commandes:
