J'ai une nouvelle tablette Thomson Teo 13.3 Android 11 (j'ai repris les paramètres d'usine, elle est tout neuf ). J'ai créé un nouveau réseau Wi-Fi sur mon routeur NETGEAR WAX202, appelons-le SSID "MyNetwork2", et j'ai demandé à cette tablette de s'y connecter. Elle tourne sous "obtaining IP address" pendant un moment, puis dit "Saved" et c'est tout ce qu'elle montre.
J'ai 5 appareils sur mon réseau domestique connectés au même routeur, et ils fonctionnent sans problème - bien qu'ils soient connectés à un réseau Wi-Fi différent. Pour tester, j'ai connecté mon smartphone Samsung LineageOS 17 à ce "MyNetwork2" - sans aucun problème. Ce n'est donc pas le routeur, j'imagine.
J'ai découvert qu'Android 11 a introduit quelques changements qui peuvent perturber la connectivité du réseau WiFi. Quelques-uns des articles que j'ai lus :
Connexion des appareils Android 11+ au SSID WPA/WPA2/WPA3/Enterprise
Depuis l'amélioration de la sécurité d'Android 11 publiée en décembre 2020, cela a changé et, par conséquent, vous ne pouvez pas ignorer la validation du certificat.
Le problème que de nombreux utilisateurs rencontreront après la mise à jour vers Android 11* est que l'option "Ne pas valider" dans la liste déroulante "Certificat CA" a été supprimée.
Bien que cela ne s'applique probablement pas à moi, car je n'utilise pas de réseau d'entreprise.
Finalement, j'ai aussi trouvé :
Problèmes de connexion Wi-Fi avec le Xiaomi Mi A2
il avait activé le WPA et le WPA2 sur l'AP. Ils ont également confirmé que ce n'était pas quelque chose que j'aurais pu faire moi-même, car il n'y a pas d'option pertinente dans la partie "face à l'utilisateur" du panneau de configuration. ...
... ce qui conduit wpa_supplicant à ignorer le fait qu'il y a un tag MBO/OCE (qui est, bien sûr, toujours présent) malgré le fait que l'AP ne supporte pas PMF comme indiqué dans l'IE RSN, et à utiliser l'IE WPA pour choisir les algorithmes de chiffrement nécessaires.
Je ne comprends pas la moitié des mots employés ici, mais j'ai essayé de désactiver la double fréquence sur le réseau WiFi, et d'ajouter à la fois WPA et WPA2 - et bien sûr, cela n'a pas fonctionné non plus.
Quoi qu'il en soit, j'ai essayé d'obtenir un logcat pendant les tentatives de connexion, lorsque le réseau WiFi est dans cet état :
J'ai essayé de ne rechercher que les éléments pertinents :
$ grep -i 'wifi\|wpa\|conn\|net' ~/Desktop/logcat2

Je ne parviens pas à comprendre les logs ci-dessus. Ils ne sont rien d'autre que du charabia pour un utilisateur final essayant de déboguer son problème.
Quelqu'un aurait-il une idée de ce qui ne va pas ici - et que dois-je faire pour que la connexion WiFi avec cette tablette sur ce routeur et ce réseau fonctionne ?
