Two identical Sonos One HAY speakers lose Wi-Fi connection in the kitchen

Hi, I really hope anyone can help here, im going crazy soon :D
 

I am having a persistent Wi-Fi problem with standalone Sonos One HAY speakers in my kitchen. I have tested two identical speakers in the same location, and the problem appears to follow the kitchen location rather than the individual speaker.

My Sonos system consists of:

  • Sonos Beam Gen 2 in the lounge

  • Two Sonos One SL speakers used as wireless surrounds

  • Sonos Sub in Lounge

  • Sonos Amp in the dining room - connected to analog sounds system

  • Two identical standalone Sonos One HAY speakers, normally used in the kitchen and bedroom

Network setup:

  • TP-Link Deco XE75

  • Only one Deco unit is currently in use, so the speakers are not roaming between different mesh access points

  • One combined SSID for 2.4, 5 and 6 GHz

  • 160 MHz enabled for 5 GHz

  • All Sonos devices are assigned to the 2.4 GHz band in the Deco app, as recommended

  • Mesh roaming is disabled for all Sonos devices

  • The kitchen speaker is approximately 2–3 metres from the Deco router

The kitchen Sonos One initially connects and works normally over Wi-Fi. After some time, however, it goes offline and disappears from the Sonos app.

Troubleshooting already performed:

  • Restarted the Deco router several times (I also does that automatically weekly)

  • Power-cycled the Sonos speakers several times

  • Factory-reset and re-added the affected speakers

  • Successfully added the speaker while connected by Ethernet

  • Confirmed that both Sonos One HAY speakers work correctly over Ethernet

  • Assigned all Sonos devices to the 2.4 GHz band in the Deco app

  • Disabled mesh roaming for all Sonos devices

  • Physically swapped the two identical Sonos One HAY speakers between the kitchen and bedroom

The important part is that the same problem occurs with either of the two identical Sonos One HAY speakers when placed in the kitchen. The speaker initially works over Wi-Fi but eventually goes offline. Both speakers work when connected by Ethernet.
 

The Sonos app currently reports:

  • Bedroom Sonos One HAY: Ethernet (WiFi Disabled)

  • Kitchen Sonos One HAY: Offline (Not Connected)

  • Dining Room Amp: WiFi

  • Lounge Beam: WiFi

  • Lounge One SL surrounds: Home Theater (wireless)

  • Lounge Sub: Home Theater (wireless)

Software information:

  • Sonos app build: 89.01.10-release+20260907.42e3be3fe

  • Sonos system build: 97.1-80312

  • Both Sonos One HAY speakers: S2

  • Both Sonos One HAY hardware version: 1.21.1.8-2.8

  • Controller device: iOS

Since the problem occurs with either speaker in the kitchen, but both work over Ethernet, it seems unlikely that both speakers have defective Wi-Fi hardware.
 

Could this be caused by:

  • Wireless interference in the kitchen, despite the short distance to the router?

  • A TP-Link Deco XE75 setting?

  • Band steering or the combined 2.4/5/6 GHz SSID?

  • Multicast, mDNS or DHCP behaviour?

  • An IP-address conflict?

  • Another Sonos or network configuration issue?

Please let me know what additional information would be useful or which settings I should test next.

    - Tried disabling fast roaming and beamforming, not change, still disappears after some time.
    - Set to 80Mhz now then, i remember it also sometimes switches to this automatically because of interference.
    - But all Sonos devices are atm dedicated to only 2,4ghz (except the wired) - should I try to now change the kitchen one to 5ghz alone and see if this can solve issue?
     

Why you should disable beamforming:

https://www.tp-link.com/baltic/support/faq/4420/

When the Deco system tries to "hand off" the device to a better signal, the device may:

  • Refuse to connect.
  • Stick to a weak, distant signal.
  • Drop the connection entirely.

Disabling Fast Roaming & Beamforming can resolve these mesh compatibility issues.

I wouldn't assign the Sonos devices to 2.4GHz, just disable the fast roaming beam forming, let the Sonos devices decide what band to use, they will make a better decision than the Deco AP.

 

 

A big clue, why you should use 40 or 80MHz? 😀

My question:

How long has this situation been occurring as the Sonos One HAY speakers have been around for years (not to mention discontinued)? By how long I mean has the issue been occurring ever since they were purchased or within recent weeks? BTW…the internal design of the Sonos One HAY speakers are the same as Sonos Ones without the HAY moniker. HAY is just a color finish. TBH my inclination is that you have network/interference issues.

About for the last 3 months the issue has persisted while trying to solve.
The router has been the same for almost a year.

Thanks for the response.

What changes occurred with your network within the last 3 months. The changes could have been by you or your ISP via update to the equipment (assuming they provide it).

Also, by chance are you using your own router connected to ISP provided gear? If so it may be that the ISP gear is still generating a WiFi signal causing Sonos gear to attach to it instead of your TP-Link Deco XE75 WiFi.

    ​@Smilja - My Deco is currently in Wifi-Router mode.
    The internet connection is supplied by Parknet through a managed switch in the basement and an Ethernet wall socket in my apartment.
    There is no modem/router in my apartment before the Deco.
    A computer can obtain internet directly from the wall socket, but the Deco is the only router protecting and managing my private home network.
    So would the AP solution be advisable here still?

     

    You can switch back to router mode anytime if it does not work out.

      There is the internet connection supplied by ‘Parknet’ through a managed switch, so I am not sure how this works.

      Does the speaker just disappear from the iOS controller app or does it disappear from the network? Does it continue to play when it disappears from the app? Can you see it using the Web app (play.sonos.com) when it has disappeared from the iOS controller? Have you tried to see if other controllers (devices) show the same problem?

      ...

      ...

      This would suggest that there is another DHCP if the computer works through the network connection without going via the Deco.

      Presumably the Deco is connected via the same network socket so there is the possibility of conflict between the Deco DHCP and the basement equipment DHCP.

      FWIW I use a Deco mesh with no issues on 160mhz with beamforming and fast roaming enabled (I have 4 nodes). I run using 'Stable mode' for the 2.4 network and use as an AP so no DHCP.

      I see you submitted a diagnostic as indicated by Moderator removal of the reference ID from your post for security measures. After submitting the diagnostic you must call Sonos tech support to discuss the data. People in this community have no access to diagnostics. My suggestion is to contact Sonos tech support who will have a better idea on how to help. On the other hand if you have spoken with Sonos tech support what did they say?
