Abstract
According to various embodiments of the present invention, an electronic device includes: a display; a near-field wireless communication circuit configured to repetitively transmit a scan signal for finding an access point; a processor electrically connected to the communication circuit; and a memory electrically connected to the processor, wherein, during execution, the memory can store commands for allowing the processor to set a transmission period of the scan signal as a first period, to determine whether it is necessary to adjust a scan frequency on the basis of a trigger for turning on the display when the display is turned on, to maintain the transmission period as the first period when the scan frequency adjustment is not necessary, and to change the transmission frequency to a second period shorter than the first period, when the scan frequency adjustment is necessary.
