Abstract

La présente demande se rapporte au domaine technique des terminaux, et concerne un procédé de configuration de fidélité sans fil (Wi-Fi) et un dispositif électronique. Le dispositif électronique est utilisé comme point de relais pour un réseau Wi-Fi d'un routeur pour étendre la couverture du réseau Wi-Fi ; et un identifiant d'ensemble de services (SSID) du dispositif électronique est configuré pour être le même qu'un SSID du routeur, de telle sorte qu'un service d'itinérance Wi-Fi non sensible peut être obtenu pour un utilisateur. Le procédé consiste à : accéder à un premier réseau Wi-Fi correspondant à un premier SSID d'un dispositif de point d'accès (AP) sans fil ; lors de la détection d'une opération d'activation d'un point d'accès sans fil Wi-Fi, apparier avec le dispositif AP ; et si l'appariement est réussi, configurer un second SSID d'un réseau de points d'accès sans fil Wi-Fi qui est le même que le premier SSID.
