Disclosed is an active scanning method in a wireless LAN system. The active scanning method comprises: a step of transmitting a probe request frame via a predetermined channel; and a step of receiving, from an access point, a probe response frame corresponding to the probe request frame via a predetermined channel. The probe response frame includes main channel information on the access point. Thus, the access point can be quickly scanned.
