Ikea Symfonisk Lamp Gen2 and Wifi.

Question

Hi,

I have a Sonos system that consists of IKEA Symfonisk lamp speakers (x5), Sonos One (x2), Play:3 (x2), and a Sub.

I kept my system on version 16.1 (April 2024) until recently, about two months ago. During that time, I didn’t have any issues — everything was working flawlessly.

At the end of January, I acquired two Sonos Roam 2 speakers, and in order to use them, I had to upgrade the system to the latest version. I also enabled auto-updates so that my system stays up to date. I use the Android app and the Sonos desktop app on Mac.

For at least two weeks now (maybe even longer — I didn’t pay close attention at first), I’ve been experiencing major issues when playing music on the IKEA lamp speakers.

Most of the time, I use a local music library hosted on my Synology NAS (same setup as in the past couple of years). I usually listen to playlists with around 250 tracks.

I’ve observed that very often, during playback on the IKEA speakers, tracks are skipped — sometimes one, sometimes multiple — with the message: “Couldn’t play track xyz”. This did not happen before on version 16.1 of the app.

At least once every two days, an IKEA speaker disappears from the list of speakers in the app.

Under Settings → Your System, there is an exclamation mark and a “Not connected” status.

Since I’m a technical person, I’ve gone through the setup: assigned static local IP addresses to all speakers, checked minimum SMB version, etc. However, nothing I’ve tried has made the system stable.

So my question is: what is going on here?

Why are the IKEA Symfonisk lamp speakers dropping from my WLAN?

The IKEA lamp speaker is in a normal wifi network, about 2 m away from the router. Before the update, I never experienced any Wi-Fi issues.

Hard to tell, with the data provided. Normally, I’d think an IP duplication issue, resolved by a reboot of the speakers and the router, with the speakers being powered down during the router reboot. But you’ve said you assigned reserved IP addresses already in the router.

My next thought is a version mismatch between your controller, and the firmware running on the Sonos devices. This would require them being temporarily wired to your router with an Ethernet cable to be updated, but this is a pretty slim possibility. When you do get them reconnected, it is worth checking in the controller for updates, though, just in case.

My other concern is ‘simple’ (not really) wifi interference , particularly from outside your network. While it’s possible it’s coming from inside your home, it’s equally possible (and has happened to me) that an outside influence has taken hold. In my case it was a new neighbor, with a new router, in a new location, stomping on the broadcast network I was using. Took a couple of days to figure that out.

I would recommend that you submit a system diagnostic, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution, particularly outside influences to your network.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
