Abstract: Examples described herein involve networking in a media playback system. In one aspect, an access point may prevent two or more grouped playback devices from being steered to different networks. In another aspect, an access point may operate as a sleep proxy for a playback device. In a third aspect, an example system may include a fixture configured to receive a bulb. Example bulbs include sound bulbs with one or more audio transducers and access point bulbs, among other examples.

Abstract: Seamless migration of an AP/STA link across channels to compensate for a changing RF environment is achieved by forecasting alternate AP communication channels to an STA prior to loss of connectivity on the link. The AP, when identifying a preferred communication channel, also identifies an alternate communication channel, and communicates this alternate channel to a coupled STA. In the event that communication between the AP and the STA is lost, the STA can quickly predict the new location of the AP, and migrate to the new channel without loss of communication state. The AP is not required to communicate to any STA that it has switched stations. Rather, the fact that the AP has switched is inferred at the STA by the inability of the STA to communicate with the AP. Thus the present invention may be used to preserve link state when a communication channel used by the AP/STA link is blocked.
