Method and electronic device for performing wireless communication by using channel list

An electronic device comprising:

• a housing;
• a wireless communication circuit located inside the housing and configured to support a wireless protocol for a wireless connection, at a time point, with one of a plurality of access points (APs) that use identical first credential information, wherein the wireless protocol comprises a Wireless Fidelity (WiFi) protocol and the first credential information comprises a service set identifier (SSID);
• a processor located inside the housing and electrically connected with the wireless communication circuit;
• and
• a memory located inside the housing and electrically connected with the processor,
• wherein the memory stores instructions that are configured to cause, when executed, the processor to:
• wirelessly connect to a first AP by using the first credential information, through the wireless communication circuit;
• receive, from the first AP, a list of first channels at least partially associated with at least one second AP having a coverage overlapping a coverage of the first AP and a list of second channels associated with at least one third AP that does not have a coverage overlapping the coverage of the first AP through the wireless communication circuit, wherein the first AP, the at least one second AP, and the at least one third AP use the identical first credential information;
• increase a dwell time for each of the first channels at least partially associated with the at least one second AP, if a number of the at least one second AP is less than or equal to a designated value;
• and
• based on the increased dwell time for each of the first channels, perform scanning with respect to the at least one second AP by using the list of the first channels, through the wireless communication circuit,
• wherein the list of the first channels comprises, but not all, a plurality of channels among channels available from the wireless protocol.
