[RESOLU] No wifi adaptater found

superludo38 · Le 19/01/2021, à 21:51

Bonjour,
J'ai un PC en dual boot W10 + ubuntu 20.04 depuis 6 mois.
La semaine dernière, j'ai perdu ma connexion wifi sur Ubuntu (je me connecte actuellement avec mon smartphone par USB).

J'ai trouvé de la documentation expliquant qu'il fallait désactiver le fast boot mode de windows, ce que j'ai fait. Mais je n'ai toujours pas de connexion wifi disponible sous ubuntu. Pouvez-vous m'aider ?
Ci-dessous le contenu du fichier wificheck,log
