Correct order to reestablish sonos system on S1 app

Hi @Michael_53 

Welcome to the Sonos Community!

Generally, for a best-possible refresh, I’d recommend the following:

1. Turn off all Sonos devices and your router
2. Once router has been off for at least 30 seconds, turn it back on
3. Once WiFi has returned, reapply power to any Sonos products that are ethernet-wired to the network. Wait for solid white lights. If no Sonos products are ethernet-wired, skip this step
4. Reapply power to wireless Sonos units
5. Wait a couple of minutes before opening the Sonos app

However, you should not need to do this - regardless of any power outages, your Sonos system should rebuild itself - at most - a couple of minutes after the router has finished booting up. As you have issues, however, you will probably find it beneficial to reserve IP addresses for your Sonos products in the router’s settings to ensure no other devices take them and cause conflicts. How exactly you go about doing this, I can’t currently say, but searching the internet for “IP reservation” and the model name of your router should yield results. Alternatively, you could contact your ISP for instructions, or get in touch with our technical support team, who have tools at their disposal that will allow them to do it for you, via remote access to a computer.

When you say “power down booster”, are you talking about a Sonos Boost (which just counts as an ethernet-wired device in the steps above) or a WiFi Booster? If it’s the latter, we recommend turning it off and keeping it off - we don’t support their use, and it could quite easily be the cause of the issues you describe. A mesh WiFi system would serve you better, though if used in conjunction with your current router should be placed into Bridge/AP mode, also to prevent IP conflicts.

I hope this helps. You may also find my article of help:
