Salut,
Je viens d'installer Fedora 18 sur un laptop histoire de pouvoir profiter de la nouvelle version de Darktable. L'installation s'est bien déroulée. Le wifi était reconnu automatiquement et fonctionnait parfaitement. Après l'update, l'installation d'un nouveau kernel, de plusieurs applications et reboot, je me retrouve sans wifi. J'ai essayé de booter avec l'ancienne version du noyau, même problème. Un message s'affiche dans la barre de notification toutes les minutes :
Echec de connexion: L'activation de la connexion réseau a échoué. Ma carte est reconnue. Les réseaux wifi s'affichent et la connexion ethernet fonctionne.
iwconfig
p2p1 no wireless extensions.
lo no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr=2347 B Fragment thr:off
Encryption key:off
Power Management:off
Not Associated.... Un problème de droits d'accès ? J'ai pensé que Firewalld ou SELinux pouvait peut être bloquer l'accès et je les ai désactivés (service firewalld stop & setinforce 0), mais cela n'a rien changé.

J'ai aussi essayé :
pifconfig down/up wlan0 & dhclient. Pas de problème.
Par contre, j'ai une erreur avec
service restart network
