The Error 230 error on your Sonos Soundbar means the speaker has lost its connection to your home network or to the Sonos app, which stops it from playing music, receiving updates, or grouping with other Sonos speakers. Restarting your router and soundbar in the correct order fixes this in most cases.

Meaning Network connectivity failure between the Sonos Soundbar and your Wi-Fi router or the Sonos app

Time to fix 5–20 minutes

What the ERROR 230 error means

Error 230 on a Sonos Soundbar points to a breakdown in communication between the soundbar and your home network. This can happen when your router changes IP settings, when Wi-Fi signal drops out, or when the soundbar’s firmware falls out of sync with the Sonos app. The soundbar effectively “loses sight” of the network it needs to stream audio and stay controllable from your phone.

It’s a common issue and usually not a sign of hardware failure. In most households it clears up once the network connection is refreshed, though repeated occurrences can point to a weak Wi-Fi signal or router settings that need adjusting.

Common causes

  • Router restarted or changed IP address without the soundbar reconnecting
  • Weak or unstable Wi-Fi signal reaching the soundbar’s location
  • Soundbar firmware out of date compared to the Sonos app
  • Too many devices competing for bandwidth on the same network
  • Temporary Sonos server or account sync issue
  • Physical interference from other electronics near the soundbar

How to fix the ERROR 230 error

  1. Restart the soundbar: Unplug it from the mains for 30 seconds, then plug it back in and wait for the light to turn solid white.
  2. Restart your router: Power cycle the router after the soundbar has restarted, then give both devices a couple of minutes to reconnect.
  3. Check the Sonos app connection: Open the app and confirm the soundbar appears online; if not, follow the in-app prompt to reconnect the room.
  4. Update the soundbar firmware: In the Sonos app, go to Settings > System > System Updates and install any pending update.
  5. Move the soundbar closer to the router or use a wired connection: A Sonos Boost or Ethernet cable can stabilise a weak signal.
  6. Remove and re-add the soundbar: If the error persists, remove the room from the Sonos app and set it up again from scratch.

FAQ

Why does my Sonos Soundbar keep showing Error 230 after a router restart?
This usually means the soundbar hasn’t been given enough time to reconnect, or your router assigned it a new IP address. Wait a few minutes after restarting, and if it still shows the error, restart the soundbar again.

Will resetting my Sonos Soundbar delete my saved settings?
A simple power restart won’t delete anything. Only a full factory reset, which is a separate and more drastic step, will erase your saved settings and room setup.

Is Error 230 linked to my internet provider or just my home network?
It’s almost always a local home network issue rather than something caused by your internet provider, since the soundbar only needs to reach your router and local network to function.
