Des modes de réalisation de la présente demande concernent un procédé de traitement d'informations, un terminal, une puce et un support de stockage, qui sont appliqués à un premier terminal. Le premier terminal comprend un premier module de gestion Wi-Fi, un premier module de communication Wi-Fi et un second module de communication Wi-Fi. Le premier module de gestion Wi-Fi établit séparément une connexion de communication avec le premier module de communication Wi-Fi et le second module de communication Wi-Fi. Le procédé comprend les étapes suivantes : un premier module de gestion Wi-Fi reçoit un message d'indication d'erreur de réception de données envoyé par un premier module de communication Wi-Fi, puis détermine, en fonction du message d'indication d'erreur de réception de données, si une condition d'accusé de réception négatif (NACK) est remplie ; si le premier module de gestion Wi-Fi détermine que la condition NACK est remplie, le premier module de gestion Wi-Fi envoie le message d'indication d'erreur de réception de données à un second module de communication Wi-Fi ; et le second module de communication Wi-Fi génère une trame NACK selon le message d'indication d'erreur de réception de données et envoie la trame NACK à un second terminal.
