Ethernet montre déconnecté mais câble branché

J'ai un Latitude E7240. Le câble réseau est branché mais le réseau Ethernet est déconnecté. J'ai essayé toutes sortes de choses avec la liste noire, la recherche de pilotes, le travail sur l'installation USB mais en vain.

Voici les caractéristiques de mon système et certains messages de journal.

Merci pour toute aide. muixca

Comme vous pouvez le voir sur cette ligne:

May 17 15:44:18 pi kernel: [    0.971359] e1000e 0000:00:19.0 eno1: renamed from eth0

votre carte réseau est renommée eno1, donc en utilisant ethtool eth0 ne donnera aucun résultat. Vous devez utiliser ethtool eno1

Utilisation lspci -v. Cela vous montrera quel module du noyau gère votre carte réseau. Si aucun module n'est répertorié, vous avez besoin d'un pilote ou éventuellement d'une mise à niveau du noyau pour que votre carte fonctionne.
