A method for setting Wi-Fi roaming, and a terminal are provided. The method includes the following. A first received signal strength indication (RSSI) value is obtained when a terminal is connected to a first AP. An RSSI adjustment value is obtained by subtracting a preset RSSI weight from the first RSSI value. A preset RSSI lower limit is set to be a roaming threshold when the RSSI adjustment value is greater than the preset RSSI lower limit, and the RSSI adjustment value is set to be the roaming threshold when the RSSI adjustment value is not greater than the preset RSSI lower limit, where the roaming threshold is used to trigger the terminal to roam between different Wi-Fi networks.
