Point d'accès sans fil non pris en charge après la mise à niveau vers 14.04!

J'avais l'habitude d'utiliser ap-hotspot sur mon ordinateur portable avec Saucy sans problème. Maintenant que je suis passé à 14.04 et que j'ai installé ap-hotspot, j'obtiens cette erreur:

Your wireless card or driver does not support Access Point mode

Voici le résultat de iwconfig:

Je jure que ça marchait à Saucy. Cela peut-il être un problème avec le pilote?

Selon ce qui suit: Table des adaptateurs sans fil/jeu de puces le mode maître n'est pas pris en charge par le pilote propriétaire bcmwl et est pris en charge par le b43 natif avec le microprogramme requis. Je vous recommande de faire:

Sudo apt-get purge bcmwl-kernel-source
Sudo apt-get update && Sudo update-pciids
Sudo apt-get install firmware-b43-installer
Sudo reboot

Tester:

Sudo iwconfig wlan0 mode master
