I have 1 Soundtouch 10 (connected via WIFI) and 1 Soundtouch 20 (connected via Ethernet) which are controlled by my iphone 5 with latests firmwares/IOS/App versions. I have 3 Access points in my house to cover everything.
Every now and than I want to turn on the Soundtouch 20 and the App cannot find the any speakers. How can I start to debug this issue ?
Which network communication is used to find the speakers ?
