An electronic device includes a Wi-Fi module configured to perform communication in a first frequency band, a communication module configured to wirelessly communicate with a given network in a second frequency band, a first processor operatively connected to the communication module, a second processor operatively connected to the Wi-Fi module and the first processor, and a memory operatively connected to the second processor. The memory may store instructions, that when executed by the second processor, cause the second processor to receive, from the first processor, a message notifying a state of the electronic device wirelessly communicating with the given network and to lower transmit power of the Wi-Fi module in response to the message.
