A wireless local area network (WLAN) client device determines the WLAN regulatory domain in which it is currently located by using information received via a non-WLAN wireless interface. Once the regulatory domain has been determined, a WLAN client device operating in the 5 GHz band, for example, an IEEE 802.1 la client device, may passively scan for wireless local area networks on channels in the 5 GHz band that are valid in the regulatory domain and may refrain from passively scanning on channels in the 5 GHz band that are not valid in the regulatory domain.
