{Résolu} Pb avec le réseau

Bonjour
Parfois j'ai un pb avec le réseau, la connexion Eth ne veut pas s'activer, même après désactivation/réactivation avec Network Manager (l'icône en haut à droite de la barre Unity)
Et en terminal :

sudo service networking restart
[sudo] password for moi: 
stop: Job failed while stopping
start: Job is already running: networking

Et même avec la coupure matérielle du WiFi c'est pareil, pas moyen de faire marcher le filaire sans rebooter.

Vous savez quoi faire ?

Merci

[EDIT] : si je débranche le dongle USB :

Re : {Résolu} Pb avec le réseau

Oooops.... j'avais le serveur DHCP KO et j'essayais de me mettre en statique sur un mauvais subnet : tout faux le guignol

Bon, je tâcherai de m'en souvenir la prochaine fois car c'est pas la première fois que ça m'arrive, mais pourtant un reboot n'y ferai rien, sauf me remettre les idées en place
N'empêche que les messages de retour de network-manager sont plutôt bizarres...
