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?

Replaced my Spectrum SAX2V1S with a TP Link AX1800 ($85 cost) and my Sonos connectivity issues disappeared.  Not sure what the problem was with the Spectrum router but cost of new router was way worth the time saved in fussing with the Sonos app on speakers disappearing.

At least you don’t have much WiFi interference. Currently I’m in an urban area. I have fiber — that’s great. On the not so great side — at times I can see about 70 access points; a combination of home mesh systems and a medical facility next door. There are a few “smart guys” who are using channels 8, 9, & 10. I suspect that some of these are “auto”.

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. 

@Airgetlam, can you Bridge the SPECTRUM?

I connected my Netgear router to the Spectrum Modem/router, and did as @buzz suggests. Never had an issue, other than Spectrum dropping more frequently than I preferred. AT&T DSL was way more steady for me. 

The older SONOS product will build its own private wireless network, SonosNet, when one or more units are wired to the network. The newest units, such as the ERA’s or any of the portable units do not support SonosNet. Using a SONOS USB network adapter, you can wire the ERA’s and MOVE 2. Otherwise, the newer units must use WiFi and, if you search, there lots of Internet “fires” burning around the SPECTRUM router.

If it was my system, I’d disable the SPECTRUM’s WiFi as much as possible or ignore it and install my own router. Actually, I’d avoid SPECTRUM if possible.

Folks, the easiest fix for any router issues is to plug one of your speakers into the router with an Ethernet cable. Your Sonos system will automatically create its own network and, just like that, all router related issues are solved. Of course, you need to have your router near enough to one of your speakers, or run some cable through your house. But for me, it was a much easier and less expensive fix than having to buy a new router. And yes, you only have to connect one speaker, not all of them. 

BTW, my issues were caused by a new router from Spectrum.

Per the support, this will not work for Era 300s

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.

I did this (enabled UPnP) and thought it was working for a bit, but then started having the same problems. Then I saw on another post, and remembered from issues I had years ago, that the best and easiest fix is to plug one (yes, it works with only one) of your Sonos speakers into your router with an Ethernet cable. Your Sonos system will create its own network, and just like that, all your router problems solved!

We travel a lot. This Spectrum router incompatibility was just another disappointment. Guess what, Roam doesn't work with hotel wifi. Last year it took 2 calls and 3 hours of Support time to make our SL One speakers work in an Airbnb. Sonos product is just too fragile. Big regret I bought it. It won't play Amazon music, can't "find" the music yet the same music plays via Bluetooth to the Roam. On and on.

I’ve found it fairly easy to wire several Sonos here, in particular the Arc and Beams since I already had Ethernet to the TVs.

A Sonos Boost is also a good option to get off WiFi IF you don not have any WiFi only Sonos Era speakers.

That’s why I use a Sonos BOOST. It can sit close to the router, without sacrificing a speaker.

Hello,

There are known Wi-Fi issues with Spectrum routers. See Incompatible hardware with an available solution

The general resolution is to use Sonos in a wired setup."

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

Just replaced my spectrum router this past weekend because Sonos customer service mentioned it’s a known issue with Spectrum routers; I always had at least 2 speakers missing! When I added two Sonos era 100s in December, the situation only got worse. I was really getting ready to return them. I have 5 Sonos speakers and was suuuper frustrated.
 

 I tried the NETGEAR router mentioned in this thread, but it didn’t work for me! Maybe I got a dud because I bought used from Amazon.

I caved and bought an Eero router fr Best Buy and omg, I wish I did this sooner…returned rented router to spectrum today. Good riddance!!! 

What model etc?

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! 

I had this same issue trying to set up two new Era 100s (my first Sonos products) - I called spectrum and had them manually switch my phone to the 2.4 gigahertz band so I could finish the setup but as soon as he switched it back to 5 the app could no longer find my system (even though the Era 100s allegedly work on both bandwidths. I bought a new router to plug into my spectrum modem (NETGEAR R6020, was $36 on Amazon) and renamed the network to my original network name, and everything immediately worked - I didn’t even have to create separate networks for each bandwidth!

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

UPDATE: my phone has reverted back to 5g and the sonos still works.

The reason I had to factory reset my sonos is that when trying to pair to the new wifi, they were still stuck on the old “system” and router. Do what works for you, just giving you my experience.
 

Happy listening. 

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. 

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. 

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.

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.

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

Badge

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.

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. :-) 

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.
