en tout cas le DHCP request à l'air de fonctionner...
donc ce ne serait pas "bêtement" un problème réseau ou WiFi
donc aussi, aucun problème de driver pour ta carte réseau...

oui, peut-être du côté du firewall ?

Après avoir exécuté resolvconf et réamorcé beaucoup de fois la 
situation a changé un peu. 
Maintenant quand je redemarre, je peu pas “”pinger” le router bien que 
l'interface soit active.
 Si je desactive l'interface et l'active à nouveau alors tout va bien. 
Le problème c'est que les changements  ne sont pas enregistrés pour le 
prochain démarrage.
Si ça peu aider celle-ci est la sortie de iptables -L.
