Abstract
Structures and methods for conserving power in wireless, multi-homed communication devices includes powering down unused network communication devices while leaving an active or most desired network communication device active. A prioritized list of the available network communication devices, based on user preferences, is used to activate the desired network communication device(s) and power down the other network communication devices.
