Certain examples accommodate data routing optimizations. An example method comprises receiving, by a first playback device, data to be directed to at least a second playback device, the data comprising: i) audio data and ii) non-audio data. The method comprises transmitting, by the first playback device, the non-audio data to the second playback device via a third playback device according to a network protocol for communication between the first playback device and at least the second playback device via a wireless communication link. The method further comprises determining, by the first playback device, that a signal strength of the wireless communication link is above a threshold, and in response to the determination, transmitting the audio data to the second playback device via the wireless communication link, wherein transmitting the audio data comprises transmitting the audio data over the wireless communication link not according to the network protocol.
