Can’t play on Sonos from within Spotify

I’ve got:

Sonos Amp, cabled to Asus RT-AX92U (which has another RT-AX92U in mesh-configuration)

Router set to wifi channel: 1

I have set the channel bandwidth manually to 20MHz (used to be 20/40Mhz)

SonosNet channel: 6

2x Sonos Play:1

I’ve got 4 analogue JBL speakers and a subwoofer connected to the AMP.

Thanks a lot to @Ken_Griffiths and @John B for helping out. I appreciate your expertise, those are superb advice, and input indeed.

Hi @Don Vito.

Thanks for reaching out and for the detailed responses, we are glad to help.

To add up with the suggestions above, upon checking with your router (Asus RT AX92U), I noticed known symptoms that are quite similar to this issue, which includes association failures with other ASUS RT routers with Airtime Fairness.

If this router has the said feature, I suggest that you may try to “disable” and see if that will help, here’s how:

1. Log into the ASUS router.
2. Under Advanced Settings, click Wireless.
3. Click the Professional tab.
4. Disable Airtime Fairness and click Apply.
5. Change the Frequency to 5GHz.
6. Disable Airtime Fairness and click Apply.

If the problem continues, it would be worthwhile checking also and making sure that the router is not blocking Sonos. 

• Download the Asus App on your mobile device.  (if you don’t have it yet)
• Ensure that your mobile device is connected to the right WiFi and launch the Asus router app.
• Tap Devices.
• Scroll to see if there are blocked Sonos devices and tap on it to open a new menu.
• Disable Block Internet Access.
• Then, test music playback, or any other activity to Sonos that was previously failing, and see if the problem will be resolved.

NOTE: You may need to reboot the affected Sonos players.

Hopefully, that helps but if not, please submit a diagnostic report using the Sonos app when an issue occurs, so we can review your system further and see if there’s anything under the hood that might be causing this issue.

Hello Annazel, 

I’ve disabled Airtime Fairness on all frequencies. No luck.

There are no devices blocked so I couldn’t unblock them.

I’ve submitted my diagnosyics, this is my confirmationnumber: 942401437.

Looking forward to you response.

Hi @Don Vito.

Thanks for your response and for your effort in submitting the diagnostic.

Upon checking on the diagnostic report, it was triggered using MAC OSX and the network connection of this controller is ‘Unknown’, meaning, it is not connected on the same network where you have your Sonos system.

• Please ensure that the controller is connected to the right WiFi network. 
• Try to use another controller (mobile device) and if the issue still occurs, please submit a diagnostic using this device.
•  

There are also transport errors detected by the system. I see that both SonoNet and your router are using the same WiFi channel (6) and that is not suggested because it can cause interference.  

In reference to @Ken_Griffiths, the Sonos component that is currently hardwired (Amp) must be directly wired to the router. You mentioned using ‘intermediary switch’, can you try to remove it for this troubleshooting, it will help us isolate the issue.

You can visit our article on reducing wireless interference to change wireless channels and move Sonos away from certain electronic devices in order to avoid interference.

I recommend changing the wireless channel on the wireless router (or access point). NOTE: This may involve disabling automatic channel assignment on the wireless router or access point.

• Log in to the wireless router or access point that Sonos is associated with through a web browser or through the router/AP's designated App.

• Change the router/AP's wireless channel to a different channel. If the router/AP uses an automatic channel assignment, it is recommended that this be disabled for this exercise. Ideally, select channels 1, 6, or 11 are the preferred non-overlapping channels.

• Test it and attempt music playback, or any other activity to Sonos that was previously failing, and see if the problem is now resolved.

If the issue still persists, please submit a new diagnostic report and reply with the confirmation number so I can check further and see if there’s anything else causing this issue.

Let us know how it goes and if you have any questions feel free to reach out, we’re always here to help.
