disappearing speakers, its not my wifi

Every time I add to my Sonos system other speakers disappear. It’s so time consuming and frustrating to have to reset several speakers just because I spent more money with Sonos. You all should be paying me since I have to spend time reconnecting everything just to add more! It’s NOT the network!

How are you adding them?  If you are following the instructions for setting up a new system instead of setting up a new unit, your speakers will disappear.  You add to a current system by going to Settings > System, and choosing Add Product.

Here is an article about IGMP Snooping. I’m sure that it’s a bit more technical than you’d like. The bottom line is that SONOS needs to be able to “multicast”. Simple phone/pad/computer access to the Internet does not need to multicast. SONOS units need to be able to chatter with each other. This is a potential reason why people are noting that their network was “perfect” before SONOS arrived -- therefore it must be a SONOS issue.

It’s possible that a wireless router is configured for IGMP Snooping (or not) by default and user access to the option is omitted in an effort to make the user interface appear “simple”.

We may be able to offer more specific advice if you provide more detail about your network. Please include model numbers.
