The Error 220 error on your Sonos Soundbar means the device has lost its connection to your home network or the Sonos app cannot communicate with it properly. Restarting your router and soundbar, then reconnecting through the Sonos app, resolves this in most cases.

What the Error 220 error means

Error 220 appears when your Sonos Soundbar can’t maintain a stable connection to your home network or the Sonos cloud service. This often happens after a router reboot, a Wi-Fi password change, or an internet outage that disrupts the soundbar’s session. The soundbar itself is usually fine — it’s the network path between your phone, router, and the device that’s broken.

This is a common issue across smart home audio devices. If you also use a Sonos system alongside other brands, similar network-based errors are covered in guides like the Sonos Soundbar ERROR Error Code: Causes and Fixes article.

Common causes

  • Router was recently restarted, updated, or had its Wi-Fi password changed
  • Soundbar is positioned too far from the router causing a weak signal
  • Temporary internet service provider (ISP) outage
  • Soundbar firmware is out of date and needs updating
  • Too many devices connected to the same Wi-Fi network causing congestion
  • Router firewall or band settings (2.4GHz/5GHz) blocking the soundbar

How to fix the Error 220 error

  1. Restart your router and soundbar: Unplug both devices from power, wait 30 seconds, then plug the router back in first. Wait two minutes before powering the soundbar back on.
  2. Check the Sonos app for connection status: Open the Sonos app and go to Settings > System > About My System to see if the soundbar is listed as connected.
  3. Move the soundbar closer to the router: Weak signal strength is a leading cause of Error 220. Temporarily relocate the soundbar closer to test if the connection stabilises.
  4. Reconnect the soundbar to Wi-Fi: In the Sonos app, select the soundbar, go to Settings > System > Network, and re-enter your Wi-Fi credentials if prompted.
  5. Update the soundbar’s firmware: Go to Settings > System > System Updates in the Sonos app and install any available updates, then restart the soundbar.
  6. Factory reset as a last resort: If the error persists, remove the soundbar from your Sonos system and set it up again from scratch using the Sonos app.

FAQ

Why does Error 220 keep coming back after I fix it?
This usually means your Wi-Fi signal is unstable at the soundbar’s location or your router is dropping connections intermittently. Try switching to a 5GHz band or moving the router to a more central spot.

Can I use Ethernet instead of Wi-Fi to avoid this error?
Yes. Connecting the soundbar directly to your router with an Ethernet cable creates a more stable connection and often eliminates network-related errors like this one.

Will resetting the soundbar delete my saved settings?
A full factory reset removes the soundbar from your Sonos system, so you’ll need to set it up again, but your streaming service logins and playlists remain saved in your Sonos account.
