Wifi indisponible sur Vaio VPCYA1V9E avec 11.04

Bonjour,
Le wifi ne fonctionne pas sur mon portable Sony Vaio VPCYA1V9E.

Dans NetworkManager les lignes Réseau sans fil et Réseaux sans fil désactivé par un commutateur matériel sont grisées. Pourtant le switch est sur ON et la led est allumée.
Si je mets le switch sur OFF le Bluetooth s'éteint, la led aussi. Sur ON, le Bluetooth s'allume, mais pas le Wifi.
J'ai essayé avec la version 64bit de Ubuntu 11.04, sans succès.
Idem avec 10.04.

Le wifi fonctionne correctement sous Win7.

Pouvez-vous m'aider?

Re : Wifi indisponible sur Vaio VPCYA1V9E avec 11.04

J'aurais du chercher plus longtemps...

J'ai appliqué la solution trouvée dans ce post

Je suis arrivé à mon but en complétant /etc/modprobe.d/blacklist.conf (sudo gedit /etc/modprobe.d/blacklist.conf) en rajoutant en dernière ligne : blacklist acer-wmi
Résultat immédiat et efficace au démarrage suivant.

Je ne comprend pas bien ce que j'ai fait, mais ça fonctionne...

Merci Jean49!
