I have had my system for a few years. It worked fine. Two weeks ago, the system would not connect. I have a sonos controller, plus use the apps on my iphone and ipad to control it. I also use the imac controller from the desktop. None of the devices or computer could access the system. I had to reset the entire system, walking around the house adding each room back in. this worked for a few days, and now it the same thing is happening. I can't access the system. Please help!
