bonsoir
j'utilise internet sur mon ordi via mon téléphone (la connexion est pas terrible mais ça fonctionne) et le signe de wifi n'arrête pas de changer, il alterne entre tout et minimum alors que l'ordi est a 1m du téléphone, se pourrait il que ça vienne de la connexion ou mon ordi fait des sciennes, merci d'avance
