[résolu] wifi disparu depuis mise à jour
Salut
Je suis sous xubuntu 14.04 depuis peu. Je surfais ce matin, des mises à jour ont été faites, le pc devait redémarrer mais j'avais reporté puis brusquement il s'est arrêté! Je l'ai redémarré et là plus de wifi 
Le commutateur est actif sur le pc et la bbox est ok car je vous ai écrit depuis le wifi via mon tel.
En haut à droite sur réseau il indique le wifi est désactivé par un commutateur matériel.
Une idée?
Désolée pour orthographe mais tel deconne aussi>:)
Merci
J'ai branché un câble réseau et voici des infos pour vous aider.

Bonjour,
Il ya visiblement un blocage. Tu peux essayer la commande ci-dessous pour l'enlever.
sudo rfkill unblock allMembre de l'April (www.april.org)
