This week at church, we began testing a new Wi-Fi in-ear monitor system that uses your personal mobile device connected to a Mac over a dedicated Wi-Fi connection. Initial testing by myself was pretty good. The quality was good and the connection was clean. But then on the first practice, we added another user to the test, and the connection was jittery. I suspect we need to fine-tine the wireless router. This it the video that details how to do it.
