[Résolu] wifi ne fonctionne plus après installation 20.04
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

La Box repérée est celle avec l'astérisque *.
Il faut mettre un seul chiffrement WPA2, comme indiqué au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

Re : [Résolu] wifi ne fonctionne plus après installation 20.04
Bonjour et merci beaucoup pour la réponse.
J'avais en effet vu cette info sur le tuto mais je parviens bien à me connecter au réseau repéré avec l'astérisque (qui est en fait un extenseur wifi du réseau wifi_lep). Je ne parviens pas à me connecter au réseau wifi_lep, qui est celui de la box.
Merci.

Re : [Résolu] wifi ne fonctionne plus après installation 20.04
Bonjour,
Tente cette commande :
Bonjour !
Merci Toutafai !
J'ai enfin résolu le problème à l'aide de Varunendra sur le forum anglophone. Tu étais très proche de la solution, il fallait finalement remplacer le contenu du fichier (et pas ajouter à la fin comme je l'ai fait). Et il fallait aussi modifier un paramètre concernant l'utilisation simultanée du Wifi et du Bluetooth dans mon cas. Voici la manipulation exacte que j’ai utilisée :echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
A priori, le paramètre "swcrypto" ne semble avoir aucune incidence sur ma connexion, mais je le laisse par simple précaution.
Le détails des options est expliqué très clairement ici (en anglais) : http://ubuntuforums.org/showpost.php?p=12943350

Merci encore pour toute ton aide !
