After broadcasting the first message, the computing device may receive the first message via a wired interface. Based on receiving the first message via the wired interface, the computing device may broadcast a second message indicating a second network topology via the wireless interface. Based on receiving the first message via the wired interface, the computing device may operate according to the second network topology. ## Claims ### Claim 1 A computing device comprising: a wired interface; a wireless interface; one or more processors; and tangible, non-transitory computer-readable medium having stored thereon instructions that, when executed by the one or more processors, cause the computing device to perform functions comprising: while operating according to a first network topology, broadcasting via the wireless interface, a first message; after broadcasting the first message, receiving via the wired interface, the first message; based on receiving the first message via the wired interface, broadcasting via the wireless interface, a second message indicating a second network topology; and based on receiving the first message via the wired interface, operating according to the second network topology. ### Claim 2 (depends on 1) The computing device of claim 1, wherein broadcasting via the wireless interface, a first message comprises: broadcasting the first message via the wireless interface periodically. ### Claim 3 (depends on 1) The computing device of claim 1, wherein the functions further comprise: prior to operating according to the second network topology, receiving via the wired interface, a third message comprising an MAC address corresponding to the computing device. ### Claim 4 (depends on 1) The computing device of claim 1, wherein the functions further comprise: prior to operating according to the second network topology, determining that the second message has been broadcasted via the wireless interface for a predetermined duration of time. ### Claim 5 (depends on 1) The computing device of claim 1, wherein the functions further comprise: while operating according to the second network topology, receiving via the wired interface, audio content; and transmitting over the wireless interface to a playback device within the second network topology, the audio content. ### Claim 6 (depends on 1) The computing device of claim 1, wherein the first network topology comprises a star network topology. ### Claim 7 (depends on 1) The computing device of claim 1, wherein the second network topology comprises a mesh network topology. ### Claim 8 Tangible, non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors of a computing device, cause the computing device to perform functions comprising: while operating according to a first network topology, broadcasting via a wireless interface of the computing device, a first message; after broadcasting the first message, receiving via a wired interface of the computing device, the first message; based on receiving the first message via the wired interface, broadcasting via the wireless interface, a second message indicating a second network topology; and based on receiving the first message via the wired interface, operating according to the second network topology. ### Claim 9 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein broadcasting via the wireless interface, a first message comprises: broadcasting the first message via the wireless interface periodically. ### Claim 10 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein the functions further comprise: prior to operating according to the second network topology, receiving via the wired interface, a third message comprising an MAC address corresponding to the computing device. ### Claim 11 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein the functions further comprise: prior to operating according to the second network topology, determining that the second message has been broadcasted via the wireless interface for a predetermined duration of time. ### Claim 12 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein the functions further comprise: while operating according to the second network topology, receiving via the wired interface, audio content; and transmitting over the wireless interface to a playback device within the second network topology, the audio content. ### Claim 13 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein the first network topology comprises a star network topology. ### Claim 14 (depends on 8) The tangible, non-transitory computer-readable medium of claim 8, wherein the second network topology comprises a mesh network topology. ### Claim 15 A method comprising: while operating according to a first network topology, broadcasting by a computing device via a wireless interface of the computing device, a first message; after broadcasting the first message, receiving by the computing device via a wired interface of the computing device, the first message; based on receiving the first message via the wired interface, broadcasting by the computing device via the wireless interface, a second message indicating a second network topology; and based on receiving the first message via the wired interface, operating by the computing device according to the second network topology. ### Claim 16 (depends on 15) The method of claim 15, wherein broadcasting by the computing device via the wireless interface, a first message comprises: broadcasting by the computing device, the first message via the wireless interface periodically. ### Claim 17 (depends on 15) The method of claim 15, further comprising: prior to operating according to the second network topology, receiving by the computing device via the wired interface, a third message comprising an MAC address corresponding to the computing device. ### Claim 18 (depends on 15) The method of claim 15, further comprising: prior to operating according to the second network topology, determining by the computing device that the second message has been broadcasted via the wireless interface for a predetermined duration of time. ### Claim 19 (depends on 15) The method of claim 15, further comprising: while operating according to the second network topology, receiving by the computing device via the wired interface, audio content; and transmitting by the computing device over the wireless interface to a playback device within the second network topology, the audio content. ### Claim 20 (depends on 15) The method of claim 15, wherein the first network topology comprises a star network topology, and wherein the second network topology comprises a mesh network topology.
