Bonjour,
après avoir exploré les différents fils de discussion sans avoir trouvé de réponse, je me permets de vous exposer mon problème.
Je suis passé de la version 18.04 à la version 20.04 et, depuis, ne parviens plus à me connecter à ma box (wifi_lep ci-dessous). Le gestionnaire wifi tourne en rond puis me redemande mon mot de passe wifi.
A noter que j'ai une prise d'extension du réseau wifi dans ma maison auquel je parviens à me connecter (wifi_lep2 ci-dessous).
J'ai suivi les instructions du post (
https://forum.ubuntu-fr.org/viewtopic.php?id=2003167) ainsi que de la page wifi (
https://doc.ubuntu-fr.org/wifi) sans succès. Ma carte wifi fonctionne puisque je peux me connecter à un autre réseau.
Je précise enfin que je vis dans un autre pays (Taïwan) ; j'ai tenté REGDOMAIN=TW sans succès.
Merci par avance pour votre aide 🙂
