A power-management system for wireless network devices includes a media access control module (MAC) that receives a first enable signal and based thereon selectively transmits and receives data packets. A clock generator module receives a second enable signal and based thereon selectively generates a clock signal that is communicated to the MAC. A power management module receives configuration information associated with a plurality of power savings modes. The power management module generates the first and second enable signals based on a selected one of the power savings modes and the configuration information.
