I bought eight Sonos speakers for my restaurant and due to a bad internet connection, I think the best solution is to wire them together somehow. The issue starts every once in a while when internet breaks and place becomes silent. The guests are not happy, I am not happy .. You can get the picture.
Can someone please suggest me how to connect all of my speakers via cable to an iPad and when internet breaks, I can play music that is on my device.
Thanks in advance
