Mon arch installée et configurée (enfin presque) j'en profite pour féliciter les auteurs des wiki, très bien faits !

J'ai suivi les wiki et fait des recherches (google, forums arch, anglais compris) et n'ai rien trouvé de concluant.

J'ai également essayé ça : https://bbs.archlinux.org/viewtopic.php?id=136749 sans succès.
En gros le matériel est reconnu mais impossible de se connecter à la box alors que sous windows aucun problème, je précise que la machine n'est pas en sortie de veille (de fait).
Tentatives par network manager et par iwconfig, sans succès !
