Bonjour,
Oui, les connections ont ete testes,
C'est une connection par carte mere integree d'un PC Dell flambant neuf.
J'ai aussi change la vitesse: 10 et 100 Mbit/s, mais pas de difference.
J'ai aussi essaye de reproduire le probleme.
La seule chose certaine pour l'instant est la non disponibilite
du reseau (bien que connecte) lorsque je demmare le PC apres
une nuit.
Le temps de reconnection est de 5 a 20 mn.
Voici un journalctl.
Ce qui me parait bizarre c'est cela:

enfin
CONNECTED_GLOBAL
qui semble etre le fontinnement correct.
Pourquoi ce lapse de temps 10 mn ?
Normalement on devrait avoir:

Je ferai un autre journalctl demain.
je ferai aussi un
systemctl stop/start NetworkManager.service
pour voir si cela permet la connextion.
Merci.
