Inventor: HUANG YUAN
IPC: H04W48/20
Filed: 2020-07-24
Abstract: A wireless fidelity (Wi-Fi) connection control method and related products are provided, which are applied to an electronic device. The electronic device supports dual Wi-Fi and includes a Wi-Fi communication module. The electronic device accesses a first access point (AP) and a second AP through the Wi-Fi communication module in a dual Wi-Fi state. A first frequency band of the first AP is different from a second frequency band of the second AP. The method includes the following. In response to detecting that the electronic device roams from the first AP to a third AP, existence of the resource conflict between the third AP and the second AP is detected. In response to detecting that the resource conflict exists between the third AP and the second AP, a connection between the electronic device and the second AP is released. As such, a situation where each Wi-Fi connection enters a sleep mode after working for a period of time in the dual Wi-Fi state can be avoided, which is beneficial to increasing network speed and reducing network delay, thereby improving efficiency and convenience of Wi-Fi connection control.
