Carte ethernet désactivée

Bonjour,

Je suis sous Ubuntu 14.04 et je pense que ma carte ethernet est désactivée car elle ne reconnait pas un réseau auquel je peux accéder depuis Windows. Le wifi fonctionne très bien.

Mon ifconfig ethernet me donne ça :

eth0      Link encap:Ethernet  HWaddr 01:b1:f5:d9:a4:2b  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          Packets reçus:0 erreurs:0 :0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 lg file transmission:1000 
          Octets reçus:0 (0.0 B) Octets transmis:0 (0.0 B)

Le ifup eth0 donne :

Ignoring unknown interface eth0=eth0.

Mon fichier /etc/network/interfaces contient :

auto lo
iface lo inet loopback
#auto eth0
#iface eth0 inet dhcp

Sauriez-vous comment la réactiver ? Tous les networking restart et autres changements que j'ai pus faire n'ont pas eu d'effet.
Merci d'avance,
giliam

P.S. : Mon lspci me donne :
