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.

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!
