Connexion impossible malgré réseau reconnu ?

Bonjour à tous.

Je vous expose mon problème.

Je possède un netbook Packard Bell dot s
Intel Atom N2600
Intel Graphics Media Accelerator 3600
2 GB DDR3 Memory
500 GB HDD
802.11b/g/n

J'étais sous Xubuntu 12.04 (Xfce) depuis un bon moment sans problème particulier. Il y a deux jours, plus de Wifi sur mon ordi : c'est-à-dire, l'ordi voit le réseau, mais si je lui demande de se connecter, il cherche quelques secondes après m'avoir demandé la clé Wifi, puis me redemande la clé, et ainsi de suite.

J'ai demandé dans une autre partie du forum, mais les manip ont conduit à une réinstallation complète du système. Voici où j'en suis : j'ai installé Xubuntu 14.04, j'ai suivi le tuto de nam1962 pour l'optimisation, et j'ai bien activé le pilote propriétaire pour ma carte réseau comme conseillé ici.

Résultat : je suis revenue au point de départ, mon système est tout neuf, mais je n'arrive toujours pas à me connecter.

Voici les infos que je peux vous donner :
