Bonjour Nicosss,
Le grep de "Ethernet" sur la sortie de lspci ne retourne rien.
Le portable est un Keynux Epure 6-ET3, lshw indique
product: P955ET1_ET3.
Mais le problème réseau est peut-être la conséquence d'un autre problème. En effet je remarque de très nombreux message incessants avec dmesg :

Plusieurs milliers chaque seconde...
En cherchant là-dessus, je trouve des infos sur le forum nvidia qui parle justement de problèmes wifi résolus :

Mais bon, cela ne m'aide pas beaucoup malheureusement
