Hi, I just want to inform others that the latest firmware for ASUS RT-AX58U, released on the 26th of
November, will make the Sonos speakers stop working (Confirmed on Play:1 and Play3).

I have tried to factory reset the speakers and reconfigure them but without success.
I don’t exactly know what is causing this, but a roll back to previous firmware resolved the issue.

FWIW, having the same problem with the latest firmware ( Version 3.0.0.4.386.42095 2021/03/09) and a Sonos Play:1. Downgrading to 3.0.0.4.384.9918 was the only thing that worked. Obviously super worrisome, since there were a number of CVEs fixed in later firmware versions.

Steps I tried (but didn’t work):

Toggling IGMP snooping (ending up at disabled)
Toggling Airtime fairness for both 2.4GHz and 5GHz (ending up at disabled)

Interestingly, after toggling the airtime fairness setting the Sonos Play:1 worked for 30 seconds before disconnecting again, and remaining disconnected..

Have you contacted Asus to find out why almost every other manufacturer out there isn’t having the same issue as Asus with Sonos?

Yes I did. Here was the response:

I understand that your Sonos Play 1 cannot connect to the router after the firmware update. I know how important it is for you to fix the issue and I apologize for any inconvenience you may have experienced. Let me help you resolve this problem.

I appreciate your time and effort in troubleshooting the issue. Based on the issue you described, please perform the troubleshooting steps as follows.

A. May disable the smart connect feature for selected models (GT-AC5300, RT-AC5300, RT-AC3100, RT-AC88U, RT-AC3200)

B. 2.4GHz connection issues:
1. Change wireless mode to 'Legacy' (Wireless -> General -> Band = 2.4GHz)
2. Change channel bandwidth to '40 MHz' (Wireless -> General -> Band = 2.4GHz)
3. Change control channel to 1, 6, or 11 (Wireless -> General -> Band = 2.4GHz) (l = lower band, u = upper band)
4. Wireless -> Professional -> 2.4GHz -> disable Explicit beamforming and Universal Beamforming

C. 5GHz connection issues:
1. Wireless -> General -> 5GHz-1 or 5GHz-2 -> Select 'Legacy', 'N only' or 'N/AC mixed' in Wireless Mode
2. Change channel bandwidth to '40 MHz' (Wireless -> General -> Band = 5GHz-1 or 5GHz-2)
3. Wireless -> Professional -> 5GHz-1 or 5GHz-2 -> disable Explicit beamforming and Universal Beamforming

D. Please downgrade to previous firmware version to check if the same problems still persist.
Then disable Airtime Fairness for both 2,4 and 5 GHz again, apply to restart the router.

If the issue persists, please fill out the feedback form that I have attached in this email for us to be able to replicate and diagnose what is causing this issue for us to come up with a resolution on how we can get this issue resolved.

The files like system log, wireless log and configuration file will help us in replicating the issue with your router.
To get the setting file:
step1. login router go to Administration->System->Change the router login name to ... then proceed to step 2.
step2. Administration -> Restore/Save/Upload setting, and you will find the 【save setting】
step3. click button【save】

And provide to us the CGF file that will be saved.

To get the system log
step1. login router
step2. System Log -> General log, you will find【save】button here
step3. click button【save】

There’s at least one thing in that response I’d take issue to.

The setting of the channel bandwidth to 40 Mhz is odd, at least to my understanding, and offers increased opportunity for interference.

But then again, I’m not a networking expert, so I’ll leave that for others to dissect.

It does seem like a form letter, not specific to Sonos, but there is some valid suggestions, I think, in it.

Frankly I think you should return the router while you can. Asus have illustrated an inability to fix their products that does not inspire any confidence.

Thanks for the candid answer. What router or mesh system would you recommend that supports wifi 6 and be fully compatible with Sonos?

I use AmpliFi devices in my homes which run a total of four Sonos households. I believe their latest model supports WiFi 6 but that’s not something I need myself.

Thanks for your answer. On second thought, a mesh wifi would definitely be overkill for our current home. I am giving the Archer AX50 router a try. It is arriving tomorrow. I will report back here for the community. If all good, I will return the Asus router.

As promised, here’s a follow-up to my situation.

I received the TP-Link Archer AX50 today. After initial set up and firmware upgrade to the latest version, all my Sonos speakers are working flawlessly. My Wifi speeds may actually be a bit faster than with the Asus router as well so that’s pretty cool. I am returning Asus to Best Buy tomorrow.

Well, I guess I may have spoken too fast. This router seems to have its set of issues too. Sigh. The wifi speed is extremely inconsistent, dropping as low as 10mbps for seconds at a time. The Asus on the other hand has been rock solid so far. A quick google search indicates this is a common issue with this TP-Link model, along with overheating problems after days/weeks of use.

So for anybody else looking for another option, this may not be it…

One more, and hopefully final update to the firmware update issue on the Asus router…

Following the thread here, I was actually able to update to the latest firmware and Sonos has been working since! Another user on that thread confirmed that worked for him/her.

This link by Asus outlines the procedure to upgrade the firmware. A factory reset must be performed after the update.

Hopefully this helps the Sonos community here.

I can confirm the solution above works.

But you have to do the factory reset!
