This is the email after getting off the phone:

“Hello Thanks for Contacting Sonos support , Here is the following email with the information we discussed before

Today we discovered that they are like 7 network devices sharing same network name > 4 devices from company neatgear and 3 from company called Humax and thats making the system to change between one or the other one so we have to make sure they have different network names or you can ask your Internet provider if they could bridge the network so we can prevent this issue from happening 

If you have any questions please give us a call”

I asked multiple times why I could not just factory reset the devices and he was ignorant. He also said he would link how to fix the situation in the email and there as nothing attached and no instructions. It seems the support person misunderstood the situation. There isn’t a secondary bridge; it’s a single network provider. I tried to clarify that while I can adjust the router settings, I don’t see how that would impact Sonos in any way. I ended the call frustrated and did factory reset all devices. I was able to connect all but 1 on the network. I left the house and returned and they were all disconnected from the app again. 

I will never buy another sonos product again. The whole point was simplicity and ease of use. I just use receivers in the future and sell this piece of $%#@.

case number is: ********
