Je précise que lorsque j'ai démarré l'ordi, j'ai eu l'accès wifi en cliquant sur "Wifi non Connecté" ---> j'ai eu le choix de plusieurs fournisseurs (la liste habituelle), et donc je me suis connecté normalement.
Pour vérifier si ça fonctionne vraiment j'ai redémarré volontairement... Et là, pas de Wifi. En cliquant sur "Wifi non Connecté" plus de choix de connection wifi comme précédemment. Je suis donc en connection filaire.
Merci de vos réponses. J'espère que ce sera pas trop difficile de rétablir ce wifi récalcitrant.
🙂
