Sonos Products and Wifi 7 routers (Asus BT10)

43 replies
4395 views

Just reporting a bug really and doing it here as support chat has been impossible to get hold of.

Recently upgraded to Asus BT10 wifi 7 mesh system. All my other devices connected fine (including the ancient stuff like nest thermostats, ring doorbells, my 14year old printer etc...) with the exception of my Sonos gear

Arc, Sub3, symfonisks bookshelves - none of it would connect.

Trying to manually reset the network settings and ultimately factory reset didn’t work, it simply wouldn’t connect to the wifi network.

Ultimately I found that disabling ‘Wifi 7 Mode’ within the router settings allowed everything to connect back up. Wifi 7 mode is backwards compatible with older devices, as proven by everything else in my hose connecting to it fine, just evidently not for sonos, they will not connect whatsoever to an Asus wifi 7 router if Wifi 7 mode is enabled.

Hopefully this can make its way to the engineers and they can push out a firmware update for these devices to work fine on a wifi 7 enabled network, as even the most ancient of my other kit can do without issues.

Hi @Cronchy

I got a reply quicker than I expected.

You mention that other devices are connecting without issue - I wonder if this is because they are connecting via 2.4GHz?

The engineer I spoke to says that if he enables WiFi 7 on his router, it is WiFi 7 only, with the caveat that 2.4GHz stays active - the result is that any device trying to connect to 5GHz in particular fails to do so. However, your Arc should only be attempting to connect to 2.4GHz in the first place. I can see that the Arc is not connecting directly to the router, however, and that could be the reason for at least some of the behaviour.

So a full understanding of the network can be had, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports - they will also be able to remotely connect to your computer (assuming you have one) and adjust router settings for you.

I hope they are able to assist.

In the interests of adding weight to the importance of Wifi7 compatibility.

I just upgraded my Wifi mesh to ASUS BQ16. I found most of my Sonos system connected: Playbar/Sub/Play:1x2/Era100, but my Sonos One did not connect. Or at least not easily or reliably. After a long chat with Sonos customer support, who were easy to get hold of and super helpfull, I discovered that for some reason the Sonos One was insisting on connecting to the AIMesh node farthest away from it, rather than the one in the same room. I was advised that I need to set the nodes in AP mode (which I am still trying to find out if that is even possible) but in the process stumbled across this Wifi7 issue and sure enough, once turned off, The Sonos One connects!

So yes please Sonos, an update to fix this would be hugely appreciated.

thanks

Make sure to update the support folks with the WiFi 7 info, the more they hear the higher priority it gets.

Posting here is good too but seems to get less priority assigned than a support call as the moderators have to feed it up the chain..

Thanks Stanley_4, I was on the phone to Sonos support when I discovered the issue so they know. Well she didn’t know then, but she knows now.

Hi @volvo707

Welcome to the Sonos Community, and I’m sorry to hear that this is affecting you too.

As it only seems to be affecting your Beam, we think a report from your system might be helpful to look at here.

Assuming your Beam Gen 2 is still connected via ethernet cable and WiFi 7 is still activated in your router’s settings, please disconnect the ethernet cable, wait 3 minutes, then reconnect the ethernet cable, wait for the Beam’s light to stop flashing white, and submit a support diagnostic from within the app. Please let me know here when you have done so, but please don’t share the number given.

If you currently have WiFi 7 disabled and your Beam Gen 2 on WiFi, please enable WiFi 7, wait 3 minutes, disable WiFi 7 and wait for the Beam to stop flashing white and submit a support diagnostic, as above.

Thank you.

Hi all,

I updated my home wi-fi system to an ASUS BT10 Wi-Fi 7 mesh. Everything (33 devices) connected, except the Sonos stuff (5x One and 1x Port).

The workaround, as I learned from this forums, is to disable “Wi-Fi 7 mode” on the router/mesh. This “solves” the problem but then I lose functionality on my router, like MLO, etc.

Please fix this. No other equipment on my network has this problem.

Thanks

Hi @fantasma

Sorry to hear that you are also having this issue. I recommend you get in touch with our technical support team - getting more cases related to this issue is the best way to affect a change.

I hope this helps.

Hi @Corry P

I contacted the Technical Support via chat and was eventually able to speak with a human representative. She told me she would forward the notes from the chat to the technical team, so they can look into the problem. The more cases we bring to them, the more likely we are to get a fix.

@Cronchy, @Corry P,

I recently upgraded to the ASUS BT10 router as well and was having the same issue. The latest BT10 firmware resolved this issue for me.

My resolution:

Upgrade to firmware version 3.0.0.6.102_36921, released 2/19.
In the router admin page, go to Network, select your Main network, and change WPA Encryption from AES+GCMP256 to AES.

I guess this means Sonos devices don’t yet support GCMP256. The Wi-Fi Alliance page https://www.wi-fi.org/discover-wi-fi/security only mentions GCMP256 under WPA3-Enterprise, so I’m not sure why it’s enabled by default for WPA3-Personal. I’m not a network engineer, so maybe someone smarter can answer that.

Absolutely legendary stuff here, thanks. My network was already set to AES (must have been there as default as I didn’t manually set that I don’t think…) but having updated to the latest firmware as you mentioned, my Sonos gear now appears to connect fine whilst WiFi 7 is enabled!

I will do some further testing but looking very promising, thank you

Thanks Eric!

With this workaround I can enable wi-fi 7 mode on the router and the Sonos equipment connects.
I guess AES encryption is good enough.
I thinks this workaround is better than creating a separate IoT network.
