Probleme connexion wifi pilote wl

Bonjour à tous !

Mon wifi marchait très bien depuis la migration vers jessie (prise en charge avec broadcom-sta-dkms), et puis j'ai du faire joujou avec ce qu'il ne fallait pas toucher, parce que le wifi est toujours présent mais ne veut plus se connecter et semble bloqué au stade d'authentification WPA.

Du coup j'ai suivi ceci : http://ift.tt/1KHvPED … 8_.28wl.29

Ça m'a permi d'avoir une jolie lumière bleue sur mon clavier sur la touche d'activation wifi qui m'indique que c'est ok, mais rien de plus
