Thanks for the reply Mujtaba.khokhar. To answer your question my network is pretty basic. I have a single router, Asus RT-AC88U all settings at default. The remaining actions in Control4 seem to run fine without any delay, quick response actually on any execution such as turning on TV, video source, lights on/off etc. The only issue i have is the music execution. I have updated the controller to the latest update. The music now takes 15 seconds to come on. One more thing to note, once the music is initiated and running all is normal. When I add a room to the music selection already running, the music comes on instantly. Thanks again.
