[Résolu] Activer réseau network-manager

Bonjour,

J'ai un PC aspire 6935 et depuis peux mon réseau s'est déconnecté. Je pense que c'est du au fait que j'ai fermé le clapet de mon portable et que du coup il a essayé d'hiberner, au redémarrage il n'a pas redémarré j'ai du l'éteindre et le rallumer. Il s'en suivi que mon réseau était déconnecté, impossible de l'activer avec le bouton (le bouton censé activer ou éteindre mon wifi).
Le wifi ne marche plus et l'Ethernet non plus, par contre le Bluetooth fonctionne.
La led indiquant l'activation de réseau refuse de s'allumer et quand je clique sur le nm-applet il me dis "réseau désactivé".

Comment réactiver mon réseau ?

J'ai effectué les manip de Lolo, à savoir que le livecd ubuntu 10.04 arrive à se connecter, j'arrive aussi à me connecter sous Windows.

Voilà les résultats des commandes :

Re : [Résolu] Activer réseau network-manager

Salut,

dans un terminal tape

sudo ifup eth0

normalement ce devrait être bon.

Re : [Résolu] Activer réseau network-manager

Salut,

Ca n'a pas l'air de marcher

$ sudo ifup eth0
Ignoring unknown interface eth0=eth0.
$ sudo ifup wlan0
Ignoring unknown interface wlan0=wlan0.

Re : [Résolu] Activer réseau network-manager

salut,

rajoute

auto eth0
iface eth0 inet dhcp

dans le fichier /etc/network/interface puis un petit

sudo /etc/init.d/networking restart

Re : [Résolu] Activer réseau network-manager

Salut,

Ok ça marche pour l'ethernet, mais pas pour le wifi, de plus mon network manager est toujours inactif, j'aimerai bien passer par lui pour pouvoir choisir mes réseau, en créer etc...

Edit :
Problème résolu : http://doc.ubuntu-fr.org/network-manage … u_1004_lts

sudo mv /var/lib/NetworkManager/NetworkManager.state /var/lib/NetworkManager/NetworkManager.state.sauv

c'était bien due à la sortie de veille qui foire.

Merci pour ta solution avec le /etc/network/interfaces qui m'a permis de me sortir de ce caca plus rapidement.

Comment on passe en réslu ?
