Connexion ethernet éphémère avec carte RealTek

Bonjour à tous, j'ai des grandes difficultés à me connecter à un réseau filaire, mais la Wi-Fi marche très bien sur mon ordi.
Je pense qu'il s'agit d'un problème logiciel spécifique à mon installation d'Ubuntu car la connexion marche quand je boote sur Windows ou un Live CD de SliTaz, mais l'ethernet n'est pas bien géré ni sur mon installation ni sur un live CD d'Ubuntu.

J'arrive de temps en temps à me connecter en ethernet en lançant la commande

sudo mii-tool eth0 --force=100baseTx-FD

Mais souvent l'icône de network-manager indique qu'elle « cherche » mais échoue la plupart du temps.

Voici le résultat des commandes pouvant vous être utiles pour m'aiguiller dans la résolution de mon problème :

Je me permets de remonter le sujet, si quelqu'un a de nouvelles idées, je suis preneur.

Avec tous mes remerciements !
