Unable to add second Boost to S2 system

I recently upgraded my S1 Sonos system to S2 (removing two original Play:5 speakers, and adding a half dozen Ikea Symfonisk bookshelf speakers). Everything was, and still is, connected to SonosNet through a Boost wired to my router that I’ve had for some time. Everything works fine after upgrading the app and adding the new speakers, and all is still on SonosNet. 

To help ensure extended range and prevent dropouts, I purchased a second Boost last week to add wirelessly halfway through the house. However, I cannot get it set up. I plug it in, choose Settings: System: Add Product in the S2 app for Android, make sure Bluetooth is on on my phone, and then wait for the Boost light to turn from white to flashing green (set up) before I press the Bluetooth button on the Boost to make it change to flashing orange (connecting). 

The S2 app on my phone never recognizes it as it scans for products to add. I’ve tried this multiple times. The original wired boost continues to work (Sonos System Info shows all products connected, as WM:0). 

I’m about to send the second Boost back since it’s not absolutely necesssary and seems very difficult to get set up with the S2 app. Is there something easy I’m missing? There aren’t any detailed setup instructions for a Boost used as a second, wireless booster for SonosNet that I can find.

Hi @Seattlenerd 

Thanks for your post!

A second Boost must be added to an existing system while ethernet-connected. Once setup is complete, the ethernet cable can be removed.

Please note that such a configuration will only help in very particular circumstances - in all likelihood, a wireless Boost will not help matters. It will only do so when there is a large physical gap between two sections of the Sonos system that the Boost can bridge.

I hope this helps.

Does the Boost show in the app if you wire it to your router, just for initial setup?

This is a second Boost to be used to extend SonosNet coverage. My original Boost is still connected to my router. There’s no indication in any Sonos documentation I could find that you have to connect a second Boost that will be used only wirelessly as a signal booster to the router for initial setup. 

The original, router-connected Boost still shows up in the app.

I understand the purpose of the 2nd Boost. My question still stands.

I appreciate the question, and I’ve answered it as well as I can. I haven’t attached the additional Boost to my router for initial setup for two reasons: there is already a Boost attached to the router, and there’s nothing in the setup instructions saying a second Boost needs to be attached to the router for setup. (I followed the standard Add Product instructions.) If it does, that’s new information.

If you are only going to follow the setup instructions, why are you here?

    To see if I missed any steps because the setup instructions that came with the Boost, and that are online, are sparse. Thanks for the reply.

    A common troubleshooting step if a speaker does not appear on WiFi is to wire it temporarily to complete setup, even if another device is already wired.

    Have you checked your WiFi meets the system requirements?

    I’d tell you to plug it into your Ethernet too.

    Sonos gear has a lot of stuff that either is not in the instructions or that is in there but is wrong or misleading.

      Thanks for the tip. I’ll just have to hope Sonos isn’t confused into thinking I’m replacing the original Boost with a new Boost. Would you first disconnect the existing Boost before temporarily connecting the new Boost to the router for setup, or would you instead plug the new Boost into the first Boost with an Ethernet cable to force it to be recognized for setup?

      WiFi does meet the system requirements -- thanks for the link. I already have 13 Sonos speakers connected, plus the original Boost. So the second Boost is more a belt-and-suspenders backup, which may not be worth the hassle to connect. But I might try the direct Ethernet connection you suggested to see if I can get it added without screwing up anything else. Thanks.
