I think it depends on which one you get. The version I had, 4 years ago, yes. I’m not sure that version is still available, but I haven’t checked, I’m happy not to have to deal with Spectrum any longer. That being said, I’m really hoping fiber gets to my location in the next several years, right now CenturyLink is the only wired possibility, and they failed four attempts to install over three months, I have too many trees to go with a satellite option, so I’m stuck with a 5G offering from a cellular company. Living in the sticks does have some connectivity restrictions. 

"Wired" is not a good solution! Results in poor, limited speaker positions.

Hi,

   As of 5/15/2024 the problem persists. I went with a inexpensive AX1500 and Sonos Beam,Sub Mini,2sl wireless . All working fine as of now.

Yes, further research shows that my particular Spectrum router - SAGEMCOM SAX1V1S - is locked down by Spectrum so you cannot change the band steering settings, which seems to be the cause of my Sonos issues.  So I will likely be buying a router and give this one back to Spectrum… but at least that should save me $5 a month!

In my case, the Sonos devices have no issue connecting to the router, presumably on the 2.4Ghz band.  The problem is really a disconnect between the Sonos “network” and the phone app, and seems to occur when my phone connects on the 5Ghz band, then I can’t “connect” to any of the Sonos devices.  As a temporary workaround, it seems like when this occurs, I can temporarily shut off the phone wifi, and turn it back on.  Usually everything then connects… at least for a while. PITA, but at least I can select music again until I get a new router.

Hope this helps someone else with this issue.

Most Spectrum routers do this with no issue. IF you are in an area where they are supplying Eero routers instead of Arris, Netgear, etc. you have to do a “trick” to get 2.4 active. See in our video below.

Would a new router be possible?

Not a huge fan of Spectrum… while I have a device of theirs that I use as a modem, I use my own router to generate my own WiFi network. 

Which Router is recommended for Sonos products?

Thanks Airgettam.  I suppose i’ll just take a shot at a new/different router then since, like you say, they are a moving target given routine chip updates.

Motorola cable modems work well with Spectrum and Sonos. I have been using the Motorola MG8702 cable modem with success.

I already ordered the amazon Eero.  Hope that one is compatible?

@Steve821 Makes me wonder why Sonos did not recommend this.

Please let us know if that is a consistent fix. 

Thanks!

ugh. Thanks for the update. Everyone says to purchase your own router… 

What model etc? 

Some routers do not allow 5GHz clients to communicate with 2.4Ghz clients. If this is your situation, when the phone signs-in on 5Ghz it cannot communicate with SONOS, but if the phone signs-in on 2.4GHz it is available to the SONOS system.

Thanks, let us know what router you do get and share if what special configuration changes you need to do. I’m shopping around but still hesitant to pull the trigger. :-) 

So how do you force your phone to sign in on the 2.4GHz band? 

You would need to give different SSID’s (WiFi name) and passwords to 2.4 and 5GHz segments. My understanding is that this is not possible with some of the SPECTRUM routers, nor is it possible to change the setting that blocks communication between 2.4 and 5GHz segments.

The phone will automatically pick the ‘best’ WiFI. Potentially you could carry the phone to an area not covered by 5GHz as the phone starts up, but this would be a very fragile arrangement because if the phone ever renegotiates its connection, it will again pick ‘best’ at that moment.

Hey - hope this helps someone. 

I just upgraded from AT&T to Spectrum. It worked fine on AT&T, older router. The new spectrum router automatically routes your phone to 5g when available. That’s why you can’t connect Sonos to your router, because you have to be on 2.4ghz to pair the devices. 

FIX: call spectrum and tell them your issue, most know what to do already. if they don’t, ask them to connect your phone (or table or whatever you’re using to pair the devices) to 2.4ghz for an hour, which they will do. 

If you are coming from upgrading from a different service or router, you will need to factory reset your speakers or it will not work. 

Within that hour, pair your devices to the network. It should work fine now because you’re on 2.4ghz. I’m messaging within this hour, so i’ve still yet to test if it works once my phone reverts back to 5g. I’m sure it does, since I’m not trying to pair devices any longer. 

Hope this helps. 

I don’t quite understand. You should never, ever need to factory reset your system, unless at the direction of Sonos employees directly. Moving to a new service/router is covered in the new router - installation instructions FAQ. 
 

I previously went from AT&T to Spectrum, in neither case was I impressed with the provided hardware, so I used their equipment as a ‘modem’, and set up my own router connected to their gateway device. Had zero issues on either, other than Spectrum going down frequently. AT&T was much more stable a connection. 

I had it consistent but now with the latest Sonos app update all is bad now!

I’m still having issues where the system loses the network and I have to unplug all my speakers and search for the system. I’m looking at this router: WiFi Router 1200Mbps, WAVLINK Smart Router Dual Band 5Ghz+2.4Ghz. Will this be a good option?? Tired of the constant disconnects with the Spectrum router!
