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? 😀

  • - Set to 80Mhz now then, i remember it also sometimes switches to this automatically because of interference.

Thanks everyone for your suggestions, the issue now appears to be resolved :)

The working configuration is:
- Router emains in Wi-Fi Router mode
- Fast Roaming and Beamforming is disabled
- All Sonos devices are now free to select either 2.4 or 5 GHz themselves

The 5 GHz channel width is currently set to 80 MHz, not sure if this effects it though, but will keep it like that :)

Enjoy your weekend!

    Returning to this one.

    After a week or so the problem returned.
    Now i am back to unplugging the kitchen speaker for 1min before it is recognised.
    But woke up this one and it was gone once again.
    Tried to restart router (it does this automatically weekly) and it comes back as well, but as mentioned before, it eventually disappears. 

    All speakers and apps are updated to newest version.

    What to do? Dunno how to re-open the topic, since the original answer stopped working.

    Looking back at old posts I noted you have Wi-Fi disabled on one speaker, that is usually a bad idea, it disables Wi-Fiby tur ing off the internal radio. If you wish to keep it wired and not move all your other capable speakers to Sonosnet you might turn  the internal radio back on and disable Sonosnet instead.

    I may have missed some details with the forum hiding them so this may be redundant.

    Is your 2.4 gHz set to 20 mHz and your 5 gHz set to 80 mHz, that seems to work best here.

    Does the App's Network section show a good or better connection to the problem speakers?

    When rebooting are youpowering down ALL Sonos then rebooting the router. That is  needed to clear some issues.

    Is there any correlation wth a kitchen microwave oven operation?

    Many years ago I had an intermittent issue much worse than yours. After I started keeping a log it obviously wasn’t quite as intermittent as I thought. It was most evenings and Sunday afternoon that were impossible. I slipped a copy of my log, along with a polite note, under my neighbor’s door. A couple days later the log, now annotated, returned. Some evenings she traveled and on Sunday afternoon she called Mom. She was using a very nasty cordless phone system with the base station located on the other side of the party wall from my kitchen SONOS unit that provided wireless coverage for some other Rooms. Fortunately, I had in-wall network wiring available and I was able to rearrange things to eliminate the issue.

      It is indeed unfortunate that many folks consider their own WiFi signal as ‘sacrosanct’, and immune from outside influences. Which any electronic signal is, even when carried by wires, it’s just a matter of ‘how much’. 

      I’ve had issues myself, both from a breaking (at least in my perception) microwave, as well as a new neighbor setting up a router that stomped all over my channel in use. Neither were easily tracked, at least using the tools I had at hand, but certainly obvious in retrospect. And, ultimately, repairable.

      Making it even worse for most folks is that many of the things using the 2.4 gHz band do not even register on most of the Wi-Fi analysis tools giving a very false impression of which is the best channel.

      Then you have the auto-tunining devices that select new channels, often disrupting things that were working fine before the channel switch. Tracking my neighbor's router's tuning antics makes me want to scream "Quit Moving and messing me up!"

      I'm set to 5 gHz channel 100, yep right in the middle of the DFS block, but none of the neighbors seems to auto-tune to the DFS range. Do not try that until you understand the DFS issues!
