I've had a new router, network switch, patch panel and APs installed at home and now I cant use my exisitng Sonos system. I can sometimes get one or two to connect but not all of them. Its as though the are connecting to different APs as separate networks. I can find all devices when I do an IP and MAC search so they are definitely connected to the same network. I have updated and reset Sonos controller and turned off all devices and turned back on. The system will not create the mini Sonos network in order to set up. Ideas please, I've had two weeks of misery.
