Connexion impossible Ubuntu 14.04

Bonjour

J'étais sous Windows 7 puis Mythbuntu 14.04 avec une connexion ethernet qui me convenait.
Depuis que je suis passé sur la Live-USB 14.04 LTS impossible de me connecter (autre aléa, je n'ai plus d'OS sur le DD).
FAI Free, DHCD ok, mode routeur (même pb quand il était pas dans ce mode)
J'utilise un portable en wifi avec l'accès via la même box
Voici les commandes

lshw

ubuntu@ubuntu:~$ sudo lshw -C network

Re : Connexion impossible Ubuntu 14.04

Avec les 5 premières pages du fofo et diverses pages internet:
Le driver r8169 correspond bien à la carte Realtek rtl8110SC.
Pour ce qui est de l'adressage IP, je serais en automatique.
Je vois pas ou est le problème de connexion.
Des idées ?
