I am frustrated beyond belief with my Sonos system. I have 20 Sonos devices that do not work and haven’t in several weeks. I’ve invested a lot of money in the system but it is functionally worthless. My wireless router is a mesh network with five satellites covering a 4000 square-foot house. Download speeds are more than sufficient to run the network. I have gone through the tedious process of unplugging every speaker, every router, every amp and rebooting the modem, the routers and each Sonos devices to no avail. It still does not work. I come from the tech industry and understand when a software update isn’t done correctly and causes bugs. I have patience and am willing to give the company a chance to fix it, but it has been way too long with no fix. I am at the point where I’m gonna give one last Hail Mary pass with tech-support and if they can’t get it running, I’m gonna sell all of it and move to another system. I didn’t buy Sonos to be a part-time job trying to make it work. Is there any hope or is to time to pull the plug and move on.
