I’ve been having issues with my Sonos system acting up (speakers cutting in and out, Alexa working but not connecting to the music services, etc) and have decided to set the entire system up from scratch. 

Is there a way to ‘reset the entire system’ or do I have to go speaker to speaker and factory reset each one? I imagine the proper procedure would be 

  • unplug all speakers 
  • disconnect all wireless devices 
  • unplug router
  • replug router
  • factory restart each speaker 
  • Build system back up one speaker at the time.

We currently have 4 zones (living room, kitchen, patio and bedroom) with a total of 7 Sonos speakers (2 Sonos One, 4 play:1 and 1 older Sonos Amp. 

 

DO NOT RESET THE ENTIRE SYSTEM.

It never cures the problem, which is almost certainly network related.

You will lose playlists, favourites, settings and achieve nothing.

I second the above advice, factory resetting is only necessary when instructed by Sonos support staff, and is only useful if an update has bricked the unit.  Factory resetting an entire system wipes out all data; services, playlists, favorites, account info, etc., and also wipes out any diagnostic info Sonos could use to help you out.  

Connection problems which appear suddenly are often caused by network problems, not Sonos problems.  The  typical cause is duplicate IP addresses.  These often show up after an update or power outage because a reboot requires the device to request a new IP, and the router, having lost track of current IP assignments, issues a new IP that is in use by another device.  To cure this, do the following:

Reboot/power cycle your devices in the following order:

Modem
Router
Switches or hubs
Wired Sonos units
Wireless Sonos units
Computers/printers
Wireless devices - phones/tablets etc.

Allow each device to come back up before proceeding to the next.  Note that you can permanently prevent duplicate IP addresses by assigning an IP to each device's MAC address in the router setup.  See your router manual for details.

And if @jgatie’s advice doesn’t cure it, there are other possibilities to explore.

One question: does your system include a wired Sonos component or are you fully WiFi?

Thanks all. This is a fully wireless setup. 

Please give @'jgatie's advice a try. 

If that doesn't fix things, temporarily wire a Sonos device to the router (but keep it at least 3 frrt from the router) and see how thst goes. Experimemt with changing the wireless channeel on your router,  trying 1, 6, and 11.
