bonjour,
ma carte réseau ayant sauté avec l'orage je suis contraint à me connecter avec une clef wifi
je dispose de deux clef :
1) une dont je ne connais pas le modèle qui perd le réseau constamment rendant le téléchargement d'une pièce jointe.
2)une tplink qui lors de la saisie de la clef de la livebox me freeze totalement le pc
Voilà le résultat de wificheck:
