Abstract
An access point including a first processor and a network device. The network device is separate from the first processor. The first processor transitions between first and second power modes. The network device includes a second processor and first and second interfaces. The second processor, while the first processor is in the second power mode, (i) causes the second interface to transmit a beacon, or (ii) receives a probe request from a client device. The second interface, while the first processor is in the second power mode, (i) transmits a probe response over a wireless local area network to the client device based on the beacon or the probe request, and (ii) receives an authentication frame from the client device based on the probe response. The second processor, in response to the authentication frame, signals the first processor via the first interface to transition to the first power mode.
