Bonjour
Depuis quelque temps, le wifi a disparu de mon ordinateur. Je ne m'en suis pas aperçu immédiatement car j'utilise une connection par câble ethernet.
Je ne comprends pas très bien le fichier wificheck.log (voir ci-dessous) mais tout se passe comme si je n'avais plus de carte wifi. Quelqu'un peut-il m'expliquer ce qui se passe ?
Merci d'avance,
André DOMPS
