receive feedback information, including the strength of a signal received from the electronic device, from the external electronic device in response to the transmission of the designated packet; determine the communication state of the designated network based on the received feedback information; and display, on the display, an indicator indicating the communication state based on the determined communication state of the designated network. ## Claims ### Claim 1 An electronic device comprising: a display; a communication circuit; a memory including instructions; and at least one processor, comprising processing circuitry, electrically connected to the display, the communication circuit, and the memory, wherein the at least one processor is configured individually and/or collectively to: identify a connection state of a Wi-Fi network with an external electronic device; obtain a first RSSI indicating a strength of a signal received from the external electronic device through the Wi-Fi network; control the communication circuit to transmit a specified packet to the external electronic device through the Wi-Fi network when the first RSSI is smaller than a first threshold value; in response to transmission of the specified packet, receive feedback information from the external electronic device, wherein the feedback information includes a second RSSI indicating a strength of a signal received from the electronic device; compare the first RSSI to the second RSSI, based on the received feedback information; and control the display to display an indicator indicating a communication state of the Wi-Fi network on the display, based on a smaller value between the first RSSI and the second RSSI, when a difference between the first RSSI and the second RSSI is greater than a second threshold value. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the external electronic device is an access point (AP). ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the specified packet is at least one of a null data packet (NDP) or a null data packet announcement (NDPA). ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the feedback information is channel state information (CSI) feedback. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to: perform a roaming trigger based on a strength of a signal related to the communication state of the Wi-Fi network being less than a specified value. ### Claim 6 (depends on 5) The electronic device of claim 5, wherein the at least one processor is configured to: based on there being no other external electronic device which can perform the roaming trigger, recognize that there is no other external electronic device which can perform the roaming trigger; and based on data transmission not being performed between the electronic device and the external electronic device, provide information related to a cause of non-performance of the data transmission. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to: provide information on the communication state based on a strength of a signal related to the communication state of the Wi-Fi network being less than a specified value. ### Claim 8 (depends on 1) The electronic device of claim 1, wherein the indicator is a Wi-Fi antenna bar type. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein the at least one processor is configured to: detect whether there is a connection with the external electronic device supporting channel state information (CSI) feedback through the Wi-Fi network. ### Claim 10 A method of operating an electronic device, the method comprising: identifying a connection state of a Wi-Fi network with an external electronic device; obtaining a first RSSI indicating a strength of a signal received from the external electronic device through the Wi-Fi network; transmitting a specified packet to the external electronic device through the Wi-Fi network when the first RSSI is smaller than a first threshold value;

a communication circuit; a memory including instructions; and at least one processor electrically connected to the display, the communication circuit, and the memory, wherein the at least one processor is configured to: identify a Wi-Fi connection state with an external electronic device supporting channel state information (CSI) feedback; based on the Wi-Fi connection state with the external electronic device being identified, identify a first RSSI indicating a strength of a signal based on the electronic device receiving the signal from the external electronic device; based on the first RSSI being less than a first threshold value: transmit a null data packet (NDP) to the external electronic device; acquire CSI feedback from the external electronic device; acquire a second RSSI based on the acquired CSI feedback; and based on difference between the first RSSI and the second RSSI being greater than a second threshold value, display an indicator indicating the Wi-Fi connection state on the display, based on a lower value among the first RSSI or the second RSSI. ### Claim 15 (depends on 14) The electronic device of claim 14, wherein the at least one processor is configured to: acquire a third RSSI corresponding to a lower value among the first RSSI or the second RSSI;
