8. A method, comprising:
-
performing a passive scan on one or more channels;
if network activity is detected on a current channel of said one or more channels, determining whether the network activity is on a preferred network;
if the network activity is on a preferred network, exiting said performing and connecting to the network;
if the network activity is not on a preferred network, indicating the channel as a valid channel of a present region;
in said performing, sending a probe request with a preferred network identifier on the current channel using a safe transmitting power level; and
if a reply to the probe request is received, exiting said performing and connecting to the network; and
if no reply to the probe request is received, eliminating the current channel. - View Dependent Claims (9)

-
a transceiver;
an omnidirectional antenna to couple to said transceiver; and
a baseband processor to couple to said transceiver, wherein said baseband processor detects a wireless local area network by selecting one regulatory domain from two or more regulatory regions in which to perform a passive scan for the wireless local area network. - View Dependent Claims (20, 21, 22)
