Sonos Era 100 : Unable to find product

You will have to provide a bit more detail if you are looking for support from other Sonos users here…

• Is this a new Sonos Household/System you are setting up or are you adding the speaker to an existing system? How many devices are setup already?
• Does your local network meet the system requirements shown HERE. Can you describe the network including router make/model WiFi protocols in use.
• Are you using an S2 Setup? (Era 100 is not S1 compatible)
• Does the mobile controller device meet the S2 App requirements shown HERE.
• Does the network have any switches (managed or unmanaged)
• Are you currently using SonosNet connectivity? (Note Era 100 does not use wireless SonosNet), but have you tried the setup whilst the device is wired to the router?

Any further information you can provide here to fellow Sonos users maybe useful in suggesting some things to try, but you need to give a bit more detail, or you can of course contact Sonos Support Staff instead. If you do the latter then it maybe best to submit a Sonos system diagnostic report from within the Sonos App and note it’s reference and then contact/chat with Sonos Support Staff via this LINK  and see what the Staff can suggest to resolve the matter.
