Spectrum problem

I have spent almost 11 hours on various telephone calls with Sonos tech support trying to get my Sonos One speakers working.  Technicians have told me that I must label my 5G and 2.4 with different names.  Spectrum tells me their routers cannot do this.  Are there cures for this problem?

Which Router is recommended for Sonos products?

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?

Having the same issue!  

Have 6 speakers: 4 Sonos 1’s, Beam and a Move.

Router is Spectrum model: SAX2V15.

Spoke to Sonos said that I have to have the ISP separate the bandwidths (2.4 and 5ghz).

ISP Spectrum says that I need a router that has a dual band option… That the modal has a feature called “Advanced Home Wifi”. That this router is not capable of separating the badwitdhs.

Sonos say’s it can be done. Who is telling the truth?? 

Anyone find a solution with this type of router or should I have to spend money on a different router to support the Sonos system?

Been having similar issues ever since we got a new Spectrum router.  All three Sonos devices appear to be connected to the router, but fall in and out on the app.  Seems very random, with constant “connection” issues… at least as it appears on the app.

Tried this today and so far it seems to have fixed the problem!

In the My Spectrum app, clicked on Router and Advanced Settings.  There is a setting there called UPnP (Universal Plug and Play), which “enables devices on your network to find each other and communicate”.  This setting was disabled… enabled it, and after the router reset now everything works!

Hopefully it continues, but so far its working consistently.

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

Please let us know if that is a consistent fix. 

Thanks!

Sadly this did not resolve the issue.  I’m thinking the change in router setting just did a restart of the router which made it “work”… for a while.  By the next morning, the same problems were occurring.

The odd thing is that each Sonos device remains connected to the router just fine.  I can press play and each one will resume playing the last station or playlist.  The problem seems to be more with the app not being able to connect to the Sonos network.

Really wish someone would figure this out!

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

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.

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?
