Instabilité du Wifi LIvebox vers Dell Vostro 3360

Bonjour,
Je crée cette nouvelle discussion car après avoir tenté quelques manoeuvres sans succès comme celle-ci : http://forum.ubuntu-fr.org/viewtopic.php?id=271640
je n'ai toujours pas un Wifi stable lorsque que je suis dans ma chambre, qui n'est pas si loin de ma box, une dizaine de mètres et deux murs à traverser à peu près, je ne comprends pas pourquoi je capte bien le wifi dans le salon à deux mètres de la box et la connexion et stable et pourquoi la connexion est si instable dans ma chambre alors que Windows, à défaut d'être fluide comme Ubuntu, gère très bien le Wifi sans déconnexions intempestives et demandes de mot de passe toutes les minutes, comment pourrai-je résoudre ce problème ?
Voilà mes résultats des commandes requises pour la section WiFi (je précise que je suis dans le salon et ai par conséquent une bonne connexion Wifi ici) :

Re : Instabilité du Wifi LIvebox vers Dell Vostro 3360

Salut,

As-tu vérifié dans le gestionnaire de pilotes additionnels, ce qui t'est proposé d'installer ? Il devrait y avoir "bcmwl-kernel-source". C'est ça qu'il te faut installer.

A+

Merci pour ta réponse, mais je viens de vérifier mais ce pilote est déjà installé, et j'ai toujours le même problème...
