Wifi qui se déconnecte et ethernet qui ne se connecte pas

Message par Thibaud2606 » 19 oct. 2012 23:41

Bonjour,

Comme il est dit dans le titre, ma connexion internet sous Debian Squeeze saute. C'est à dire que en wifi, j'ai un accès à internet, mais au bout d'un certain temps, je suis obligé de me déconnecter puis de me reconnecter afin de récupérer internet. Et mon ethernet n'a jamais fonctionné sauf une fois si je me souviens bien grâce au network manager.

Je ne m'y connais pas énormément sous Linux mais en éditant le fichier interfaces ainsi que le fichier resolv, cela n'a rien changé à mes soucis.

J'espère que je pourrais trouver votre aide ici !!!!!! :)

Re: Wifi qui se déconnecte et ethernet qui ne se connecte pa

salut,
mwé, ça m'inspire pas trop… si ce n'est un bug de Network-Manager. :)

As-tu fait les vérifications qui s'imposent?
  • connexion en liveCD/USB en wifi et filaire
  • changement du câble rj45
As-tu essayé de faire un clic droit sur l'icône NM, modifier les connexions pour vérifier qu'en filaire tu sois bien sur eth1 et pas eth0? Adresse MAC 00:15:58:15:71:F7

Quand tu fais une modification sur NM, il faut le relancer

Code : Tout sélectionner

sudo service network-manager restart
Modifier "resolv.conf" ne sert à rien si tu utilises NM, il écrase le fichier. ;)

Que donne

Code : Tout sélectionner

ls /etc/NetworkManager
