wifi périphérique occupé

Bonjour la communauté!

J'ai un problème de connexion wifi (qui marchait très bien avant que mon alimentation grille). Ma carte wifi fonctionnait sans drivers. Après plusieurs manipulations en tout genre, j'ai ré-installer Ubuntu 10.04 (en gardant mon /home c'est magique).
Quand je tape:

sudo ifconfig wlan0 up

j'obtiens

SIOCSIFFLAGS: Périphérique ou ressource occupé

alors j'ai cherché et j'ai trouvé ceci.
J'ai fait ca:

1) ouvrir un terminal
2) taper gksudo gedit /etc/grub.d/10_linux
3) ajouter pnpbios=off  acpi=force irqpoll au bon endroit:

 cat << EOF
menuentry "$1" {
EOF
  save_default_entry | sed -e "s/^/\t/"
  prepare_grub_to_access_device ${GRUB_DEVICE} | sed -e "s/^/\t/"

  cat << EOF
    linux ${rel_dirname}/${basename} root=${LINUX_HOST_DEVICE} loop=${loop_file_relative} ro $2 pnpbios=off  acpi=force irqpoll
    initrd ${rel_dirname}/${initrd}
EOF
  cat << EOF

5) Enregistrer les modifications et fermer le fichier
6) dans le terminal taper sudo update-grub
7) Redémarrer l'ordinateur

Mais ca ne fonctionne toujours pas: Périphérique ou ressource occupée !!!!!!!!
un truc a ajouter dans blacklist.conf? pourtant avant je n'avais rien fait de spécial et ca marchait.
Merci d'avance de l'aide que vous pourrez m'apporter.

Re : wifi périphérique occupé

Bon ben ca marche! je ne sais pas comment!!
Ce matin j'allume mon PC et il me dit de rentrer la clé WAP/WEP....
Alors que hier soir j'ai cherché encore jusqu'à point d'heure sur les forums et que depuis ce post, je n'ai touché à rien (sauf quelques paquets installer pour le blu-ray).

Si quelqu'un a une explication, je reste intéressée.

je poste ce que j'obtiens de nouveau avec les commandes précédentes:
notemment une nouvelle ligne lors de "lsmod":
