Sonos Speaker Keeps Disconnecting: Possible Causes

There are several reasons why your Sonos speaker may keep disconnecting. The good part is that most of these reasons aren’t hardware-related, as such simple troubleshooting procedures can be enough.

  • Bugged/Outdated Sonos Firmware

The most common cause of Sonos system disconnecting is a firmware failure. Often experienced in the form of glitches, you may notice your device stop playing for some seconds, then reconnect again as if all is good.

Usually, when this happens, you want to check if your firmware is up to date – that’s if other issues internet and power are stable.

  • Issues with Sonos Control Device

Just as the Sonos firmware may occasionally malfunction, so can the controlling app on your smartphone. Many times, it’s always an issue with your app becoming outdated, but there are some times when your phone may no longer effectively support the Sonos control app. While that’s the case, simply clearing your app data will often solve the issue if you find a new update on your Play Store or AppStore.

  • Poor Network Connection

The Sonos speaker uses an internet connection to play from streaming services. If in any case, you have a weak Wi-Fi connection or your router settings happen to be interfering with the Sonos speaker, then you’re likely to experience short breaks while it’s playing.

In other cases, it can be that the ethernet cable or port of your Sonos speaker is damaged or not connected properly, causing a network issue that can lead to frequent disconnection.

  • Issue with Streaming Service

There are times when the disconnecting issue may not be caused by your speaker or even its controlling app.  It can be a result of the streaming service you’re using not being stable.

In most cases, the best you can do is see if you can reduce the streaming quality, other than that, you may just need to change service altogether.

Sonos Speaker Keeps Disconnecting: How to Fix

Sono’s speakers are quite durable, as such, it’s very unlikely that a malfunction is being caused by hardware damage. You only have to be a little bit IT savvy to carry out the troubleshooting measures.

  • Factory Reset your Device

This is often the first troubleshooting procedure you want to try before anything else; even a firmware update comes after this. Meanwhile, simple power cycling can also do the trick quite well. Here’s a quick step-by-step guide to factory resetting your Sonos Speaker.

  1. Unplug the power cord from the back of the speaker.
  2. Wait for at least 10 seconds.
  3. While holding down the Join button (or Play / Pause or Mute button, depending on your speaker model), plug the power cord back in.
  4. Continue holding down the button until the speaker’s light starts flashing orange and white.
  5. Once the light flashes green, the speaker has been factory reset.
  • Check for Firmware Update

There are times when a simple factory reset wouldn’t do, you may need to download a firmware update. In most cases where this is the solution, it’s either your current firmware version is now too old, or there was a flaw in the previous update for your model. Here’s a step-by-step guide to updating Sonos speakers with the app.

  1. Open the app and navigate through Settings >> System >> System Updates
  2. If there’s an update available, it will be listed under available updates
  3. Tap on it to download, once downloaded, the installation wizard will begin automatically
  • Check your Internet Connection

First, you want to make sure that you still have an active internet subscription, then proceed to confirm that your ISP is currently active, and then check if the ethernet cable (if you use a model with one) is still working. If everything looks good, you may try restarting/power cycling the WiFi router as this might do the trick.

Meanwhile, you want to make sure that your router isn’t too far from your speaker or you may have a weak signal which in turn, can cause occasional disconnection. Also, you may want to change the 2.4GHz wireless channel on your router to see what gives.

  • Contact Support

Despite it not being the exact solution, you may be expecting, it sure gets the job done especially if you have a product with a valid warranty. In the US, Canada, and Mexico, Sonos speakers come with a 1-year warranty, in Europe, you can get up to 2 years, and warranty in other countries depends on the specific speaker model.

After trying the options above and you’re still being faced with this problem, you may want to contact support and see if you qualify for a warranty claim. This should always be your last resort. Also, Sonos’ support team is more likely to have a solution if it’s a zero-day problem that’s causing the disconnection.
