Abstract
A electronic device includes a memory, a communication circuit that supports plural frequency bands for wireless local area network (WLAN) communication, and a processor operably connected to the memory and the communication circuit. The processor establishes WLAN communication with an access point (AP) over a first frequency band among the frequency bands, compares, based on a signal of a second frequency band different from the first frequency band being detected, the first frequency band with the second frequency band, determines, based on the second frequency band being higher than the first frequency band, a change in a strength of a signal received over the first frequency band, estimates, when the change indicates an increase in the strength, a link quality for the AP over the second frequency band, and switches the first frequency band for WLAN communication with the AP to the second frequency band based on the link quality.
