Time to fix 10–20 minutes
Tools needed Sonos app, Wi-Fi router access, smartphone or tablet

What the Error 800 error means

Error 800 appears when your Sonos Soundbar loses its connection to the wireless network it needs to communicate with other Sonos speakers and the Sonos cloud service. It can happen during setup, after a router change, or randomly if your home network becomes unstable. The soundbar itself is usually working fine — it’s the link between the device and your network that has broken down.

Common causes

  • Wi-Fi router has restarted, changed channels, or lost internet access
  • Soundbar is out of range or blocked by walls/interference from other devices
  • Router firmware is outdated or has a temporary glitch
  • Network name or password was changed without updating the soundbar
  • Too many devices connected to the router causing network congestion
  • Internet service provider outage affecting your home connection

How to fix the Error 800 error

  1. Check your internet connection — Confirm other devices in your home can browse the internet normally. If not, restart your router and modem.
  2. Restart the soundbar — Unplug it from power for 30 seconds, then plug it back in and wait for it to fully boot.
  3. Move the soundbar closer to the router — Temporarily reduce the distance or remove obstructions to rule out a weak signal.
  4. Reboot your router — Power cycle the router for a full minute, then let all devices reconnect before testing the soundbar again.
  5. Rejoin the Sonos app network setup — Open the Sonos app, go to Settings, and run the network setup wizard to reconnect the soundbar to Wi-Fi.
  6. Update router firmware — Log into your router’s admin page and install any pending firmware updates, then retest the soundbar.

FAQ

Why does my Sonos Soundbar show Error 800 only sometimes?
A. This usually points to an unstable Wi-Fi signal or a router that occasionally drops connections, rather than a permanent fault.

Will resetting my router fix Error 800?
A. In many cases yes, since a router restart clears temporary network glitches that block the soundbar’s connection.

Do I need to factory reset the soundbar for this error?
A. Usually not. Try reconnecting through the Sonos app first, as detailed in guides like Sonos Soundbar ERROR Error Code: Causes and Fixes, before attempting a full reset.
