[résolu] panne wifi étrange

fracko69 · Le 20/05/2024, à 17:20

Bonjour à tous,
je suis sur Lubuntu (20.04 LTS)
Je peux me connecter en filaire et sur le hotspot de mon téléphone en wifi, donc le wifi est fonctionne MAIS par contre la connexion wifi à ma box (Bouygues) ne fonctionne plus.
J'ai fait un full upgrade et rien changé aux paramètres de ma box (pas de filtrage d'adresse MAC par ex)...
Si quelqu'un a une idée, merci d'avance !

Bonjour,

Il faudrait fournir, en te servant du Retour utilisable de commande, un wificheck qui rassemble ces informations > Configuration wifi.

Étape 2 : Il ne reste plus qu'à copier le contenu du fichier wificheck.log (et non le fichier wificheck qui est le programme qui a généré le fichier wificheck.log) situé dans le dossier personnel et le copier sur le forum.

Lecture conseillée > memento des balises code.

voilà :
(j'ai viré les infos de connexion des box des voisins et masqué le nom de mon réseau)

Tente :

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

voir § 6 - C du > [Tuto] Pas de Wi-fi ? Éléments importants à vérifier, et redémarre l'ordi pour tester le Wi-Fi.
