[résolu]Wifi ne fonctionne plus 12.04.1

Bonjour,
au démarrage de ce matin plus de wifi (Realtek RTL8188CE) sur un CLEVO W253HU.
Peut être du à la mise à jour d'avant hier, pilote plus géré, mais bizarrement hier il fonctionnait.
Si quelqu'un à une idée du problème.

Re : [résolu]Wifi ne fonctionne plus 12.04.1

Je reviens apporter un complément.
L’absence de ligne "Kernel driver in use:" du retour de lspci -k ma fait penser que celui-ci n'est pas chargé mais pourtant il à l'air de l'être.
lsmod | grep rtl8192ce

Je cherche mais je ne suis pas spécialiste.

Re : [résolu]Wifi ne fonctionne plus 12.04.1

Bonjour et merci pour la réponse mais j'ai tout réinstallé depuis et surtout mis à jour le firmware du SSD OCEANE pour le TRIM et c'est nickel depuis.

Cordialement.
