Bonjour à tous, je rencontre depuis mon arrivée chez Orange des déconnexions régulières sans comprendre d'où cela provient.
Ma fibre arrive dans un WAS-110 8311 v2.8, raccordé sur un BananaPi R4 faisant tourner OpenWRT 24.10.1.
Mes débits sont de 7200mb/s en descendant et 5600 en montant.

Les tutos utilisés sont:

 - https://lafibre.info/remplacer-livebox/remplacement-de-la-livebox-par-un-routeur-openwrt-18-dhcp-v4v6-tv/

Tout va bien, sauf cette histoire de déconnexion toutes les environs 23h. J'ai alors un cron qui ping toutes les 2 minutes pour relancer les interfaces WAN et WAN6 quand ça arrive.

J'aimerais bien comprendre d'où ça vient afin d'éliminer le problème.

Veuillez noter que même si eth2 devient down, je ne perds pas le lien shh ou interface web du WAS-110.

Voici un extrait qui me semble pertinent des logs:
