Abstract

La présente invention concerne un procédé et dispositif de connexion Wi-Fi, se rapportant au domaine de la communication, et utilisés pour résoudre le problème de la faible vitesse des dispositifs électroniques accédant à un réseau Wi-Fi. Après avoir émis une trame de demande de sonde, un dispositif électronique reçoit une trame de réponse de sonde en provenance d'un point d'accès, la trame de réponse de sonde transportant des informations de configuration Wi-Fi d'un réseau Wi-Fi fournies par le point d'accès, utilisées pour que le dispositif électronique accède au réseau Wi-Fi; et, sur la base des informations de configuration Wi-Fi transportées dans la trame de réponse de sonde, le dispositif électronique peut accéder au réseau Wi-Fi.
