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 2.4 GHz band, for example, an IEEE 802.11b/g client device, may actively scan on channels in the 2.4 GHz band where transmissions are permitted by the regulatory domain without first passively scanning on channels in the 2.4 GHz band.
