    Abstract: A method for establishing a WLAN connection includes, in response to first input of a user, displaying a first setting interface that includes at least two identifiers pointing to a first hotspot, where a first identifier in the at least two identifiers indicates a password-free connection to the first hotspot by using a first application, and a second identifier indicates a connection to the first hotspot by using a native wireless local area network of the terminal. The method further includes, in response to an operation of selecting the first identifier by the user, establishing a WLAN connection to the first hotspot by using the first application. The method further includes, in response to an operation of selecting the second identifier by the user, establishing a WLAN connection to the first hotspot by using native WLAN connection logic of the terminal.
