IKEA SYMFONISK Speaker Not Connecting or Playing

Identifying the Issue

If your IKEA SYMFONISK Floor Lamp Speaker is not connecting or not playing audio, you may experience the speaker being invisible in the Sonos app, audio cutting out mid-stream, the speaker going offline repeatedly, or the setup process failing to complete. The SYMFONISK Floor Lamp Speaker combines a floor lamp with a Sonos-powered speaker, connecting over Wi-Fi for audio streaming. Since it runs the Sonos platform, most troubleshooting follows Sonos networking patterns rather than IKEA's Zigbee or Thread protocols.

Common Causes

• Wi-Fi signal weakness — Floor lamps are often placed in corners or behind furniture, which may be Wi-Fi dead spots
• Router or network change — Changing your Wi-Fi password, switching routers, or updating router firmware can disconnect the speaker
• Power supply issue — A faulty power cable or loose outlet connection can prevent the speaker from booting properly
• Sonos software conflict — Mismatched firmware versions between Sonos devices or an outdated Sonos app can cause connection failures
• IP address conflict — Another device on your network may have been assigned the same IP address as the speaker

Step-by-Step Fixes

1. Verify power. Confirm the floor lamp is plugged in and the outlet is working. The speaker portion shares the lamp's power cord, so if the light works, the speaker has power. If neither works, try a different outlet.
2. Restart the speaker. Unplug the SYMFONISK Floor Lamp from power, wait 30 seconds, and plug it back in. Allow 2 minutes for the speaker component to boot and attempt to rejoin the Wi-Fi network.
3. Restart your router. Power cycle your router and modem. Once fully back online, open the Sonos app to see if the speaker reappears. Many Sonos connectivity issues resolve with a simple router restart.
4. Check Wi-Fi signal at the lamp's location. Use your phone to check Wi-Fi signal strength where the floor lamp sits. If the signal is weak, relocate the lamp closer to the router, add a Wi-Fi mesh node, or connect a Sonos device to Ethernet to enable SonosNet.
5. Update the Sonos app and firmware. Open the Sonos app and navigate to Settings > System > System Updates. Install any pending updates for the app and all connected speakers. Firmware mismatches are a common cause of connection drops.
6. Reconfigure the speaker on a new network. If you changed routers or Wi-Fi passwords, the speaker cannot reconnect automatically. In the Sonos app, go to Settings > System > Network and follow the prompts to update the Wi-Fi credentials for the speaker. You may need to temporarily connect the speaker to the router via Ethernet to push the new credentials.
7. Factory reset. Press and hold the connect button on the back of the speaker while plugging it in. Hold for approximately 5 seconds until the LED flashes amber and white. Set it up fresh through the Sonos app.

When to Contact Support

If the speaker portion does not power on at all while the lamp portion works fine, there may be an internal hardware issue with the speaker module. Contact IKEA customer support for warranty service. For persistent network issues after a factory reset and fresh setup, contact Sonos support — they can run remote diagnostics on your Sonos network.

Prevention Tips

Test Wi-Fi signal strength at the intended lamp location before committing to it as a permanent spot. Assign a static IP address to the speaker in your router's DHCP settings to prevent IP conflicts. Keep all Sonos devices on the same firmware version by enabling automatic updates in the Sonos app. If your home has multiple Sonos products, connecting at least one to Ethernet creates SonosNet, a dedicated wireless mesh that greatly improves reliability for all wirelessly connected Sonos speakers including the SYMFONISK Floor Lamp.
