Many have commented that after making changes to their network that their Sonos system is not working properly. Issues range from speakers not being recognized in the Sonos app and/or drop-outs. Some of the more common network maintenance/changes are:
- Replacing/upgrading a router
- Moving from a single router to a Mesh Network setup
- Changing Internet Service Provider (ISP)
- Moving to a new dwelling with network hardware you own *
Those projects need not be an unpleasant experience as it relates to Sonos. Here are tips that can keep a Sonos smile 
on your face and avoid frustration. First…
- Unplug all Sonos components
- Do not factory reset any Sonos components
- Do not change the SSID and Password for your network **
If changing your ISP and using their hardware insist that they assist you to change their proprietary SSID and Password to the one’s you were using before.
- Setup your network (completely) before doing anything with Sonos
If moving from a single router to a Mesh network (main router and satellites) make sure to configure it properly so that none of the satellites have DHCP capability to create/assign IP Addresses. Only the Main router should have DHCP functionality. ***
- Check for updates to your device (install if available)
- Make sure your device connects to your network using the same SSID and Password as before
- Delete the Sonos App from your device
Now you can Plug-in your Sonos components and let each come back. Wait seven (7) minutes after plugging in the last Sonos component before proceeding to the next step.
- Re-install the Sonos app
- Open the Sonos app
- Select “Join an existing system”
- Sign-in with your Sonos credentials
Everything Sonos should be as it was before including voice assistants. Enjoy your Sonos!
Glossary of Terms

** If changing the SSID and/or password is necessary follow the Sonos steps in this link
*** If you connect the Main router to the ISP’s combo router/modem make sure that the router side is “disabled” or placed in “bridge mode” so as not to create a second WiFi network.
