Spectrum problem

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. 

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

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’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! 

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? 

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