[RÉSOLU] Connexion wifi non trouvée ce matin
Bonjour,
Mon ordi ne trouve pas la carte wifi ce matin.
Est-ce un problème matériel ?
Bonne journée
EDIT
Dell Latitude E7072
Problème matériel. Après démontage, une petit pièce métallique (lamelle) qui sert de fixation de la carte wifi et qui recouvre également les deux connexions à la carte faisait masse sur une cosse. Ajout d'un isolant adhésif sous une des ailes de la lamelle métallique pour éviter toute mise à la masse sur les cosses .
Redémarrage de l'ordi et connexion wifi retrouvée.
Si vous voulez voir de quelle lamelle métallique, il s'agit c'est à cette adresse
