Carte WIFI PCI reconnue mais inactive

Bonjour

Je viens d'installer Ubuntu sur mon PC en virant Windows (donc pas d'autre OS), il est équipé d'une carte WIFI PCI de US Robotics. La carte est bien reconnue par Ubuntu mais elle est en mode "désactivée". De ce fait je n'arrive pas à me connecter sur mon réseau sans fil.
Qui peut m'aider?

PS: je suis débutant Linux, donc soyez cool.
