Abstract: An electronic device is disclosed. In addition, various embodiments recognized through the specification are possible. The electronic device includes a housing, at least one antenna located in the housing, a Wi-Fi module that is electrically connected with the at least one antenna, supports a Wi-Fi protocol, and includes one core, a processor that is located in the housing and is operatively connected with the Wi-Fi module, and a memory operatively connected with the processor. The memory stores instructions, when executed, causing the processor to establish a Wi-Fi link on a first channel with an access point (AP), through the Wi-Fi module, establish a mobile hotspot link on the first channel with an external electronic device, through the Wi-Fi module, detect an event associated with a change in state of the Wi-Fi link, and change a state of the mobile hotspot link, based at least on the detected event.

Abstract: The present disclosure relates to a wireless communication method using near field communication, and an electronic device, and in the electronic device supporting first near field communication and second near field communication, a request for the second near field communication is confirmed while the electronic device is connected to a first external device through the first near field communication, circumstantial information related to the first external device (for example, the intensity of an electric field signal) is checked on the basis of at least the confirmation, and a second external device can be connected to the first external device (for example, an AP) or to a third external device (for example, base station (server)) through the electronic device by using the second near field communication, when the circumstantial information satisfies a predetermined condition. In addition, other examples are possible.
