Hello everyone,

Here’s details

Sonos always been on 2.4ghz private wifi, we have three routers, one for pos system(toast), one for customers, and one for management(2.4ghz/internal5ghz), Sonos has always been connected to the management WiFi. Today for some reason, it has trouble connecting to the management, so I forgot system and did it on the 5g customer wifi, was on the phone with Sonos while this happened, 3-4 speakers connected but two of them were on management wifi and the other 2 were on customer 5g, weird. I had connected to customer 5g on mobile and set them up on that wifi but my system wouldn’t show up unless I was on management wifi. Reset everything and tried again. This time I deleted the management wifi and made a wifi called Sonos just for Sonos. After that, I never got another speaker connected. I would go through all the steps, get to the part where it wants me to type in the wifi password, then it wouldn’t never connect and ask me to try again until it prompted for use of ethernet. While on the phone with support i used ethernet and IT STILL DIDNT CONNECT. First Sonos support guy said I needed to bridge because my speakers kept trying to connect to different ip addresses. The other guy just kept trying to reset everything and try over and over until I got tired of him. I know for a fact it has to be a network error and is probably a cluster of stuff, but remember that it was working before it just wasn’t consistent. We have Comcast business and pay for the highest speed. Out 2.4ghz was about 50-70mbps


Weird things I noticed

-after changing the wifi from management to Sonos, the computer in the back was still connected to management through Ethernet.

-tried to ping the Sonos wifi with cmv but it didn’t work

-wifi still worked fine on different devices with searches and stuff

-ISP can only see Sonos WiFi and internal btw. I don’t think there’s another modem with management wifi or anything like that, just a bunch of switches
 

Factory reset speakers

Restarted router

Was On support with both isp and Sonos support for 4+ hours, at one point on the phone with both and let them talk to try and figure out

Disabled 2.4ghz wifi and created new one

used Ethernet straight to modem/router

used multiple devices/ none worked

factory reset wifi, didn’t work

Currently waiting for a technician to come find out what’s going but thought I’d shoot my shot here

 

Your network config is unclear. Do you have VLANs for each network, or are they on separate subnets, or are they just 3 SSIDs onto one subnet? Are the networks isolated from each other?

What device(s) are running the Sonos app?

If on iOS, does “Phonos Plus” from the App Store find any/all of your devices?

You say both “Sonos has been on private” and “Sonos has always been connected to management”, which is it?

Maybe a diagram would make this clearer but your description is, frankly, a mess.


also noticed that when I’m trying to connect to a device after typing in WiFi password, I can see it show it was added in the system for a split second in the background but then it goes away, never connects, the furthest I’ve gotten to connect is using a different wifi, such as internal or the customer wifi. It says it’s connected but it won’t show up on the system. Says to unplug and plug back in if I don’t see but it never shows

I do not know what do you mean, the Comcast business is the ssid, the other systems are connected to it, they are all switches, they are all in the same room close to eachother. I have a iPad 10th generation, iPhone 14 and android, that have tried running the app. Private and management are the same WiFi I just meant that management WiFi is a wpa2 psk. 
 

no devices found on phonos plus, I apologize for the messiness


So I used the 2.4ghz wifi to start the connection, but then when I try to put the password in for Sonos to connect, doesn’t let me. So then I changed networks to the internal wifi, and it says it’s connected but I may need to plug it out and back in. Then when I connected back to the 2.4ghz network it showed that I have a system on this network(which is not the network I connected to when adding the product) and the play 1 isn’t registered and asked me to “fix it”. I go through the steps and it says this. This speaker has already been updated btw yesterday.
