Bonjour à tous,
Je suis sous Debian 11 avec Gnome 3.38, et j’utilise le VPN secure core de Proton Suisse-France qui se connecte automatiquement avec la connexion au réseau wifi de la bbox (Bouygues Télécom).
Depuis hier, je ne peux plus accéder à internet bien qu’il continue à se connecter automatiquement au réseau wifi sans VPN. Avant de se connecter, j’ai remarqué qu’il indique l’icône de connection ethernet alors qu’il n’est pas connecté en filaire.
Le plus curieux, c’est que mon second ordinateur qui est sous Lubuntu et qui est configuré de la même manière avec Bouygues et Proton a exactement le même soucis - alors que ma connexion internet fonctionne sur mes autres périphériques, comme mon VPN.
Voici le résultat de quelques commandes réseau :
