Ubuntu 12.04 ne montre pas la connexion câblée, Windows 7 ne
J'ai une connexion câblée dans mon dortoir étudiant qui ne parvient pas dans le gestionnaire de réseau avec 12.04. Cela fonctionne avec Windows 7 cependant, donc je ne dirais rien.
Sur une partition disponible de mon disque dur, j’ai essayé d’installer une autre version 12.04, juste pour être sûr que ce n’était pas une configuration erronée: en fin de compte, cela ne fonctionne pas non plus.
La chose amusante est que NM reconnaîtrait la connexion jusqu'à hier, alors j'ai pensé qu'une mise à jour s'imposait, mais rien dans les journaux ne semble pouvoir briser quelque chose lié au réseau.
Mon /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
dns=dnsmasq
[ifupdown]
managed=false
Mon /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
#iface eth0 inet dhcp
Je ne sais pas pourquoi la dernière ligne est commentée, mais j'ai essayé de la supprimer, mais cela ne fonctionnerait pas et, pire encore, il indiquerait "périphérique non géré". J'ai ensuite essayé de définir managed=true, mais il est revenu à ne pas reconnaître la connexion et j'ai donc tout annulé.

Une idée?
Il s'avère que certains câbles et commutateurs ont posé des problèmes. Ce n'est donc pas la faute d'Ubuntu!
