change of wireless network issue.

I have a sonos arc and a subwoofer that I wanted to move to another wireless network in my network. Same hardware, same access point same firewall same switch just a new wireless network. To make sure I had the password correct I connected my cell phone and it connected OK and then I moved six Alexa devices and nine other devices to this network without a hitch. I go to change the Wi-Fi network on my Sonos and six times. I’ve tried six times I get an error that it cannot connect to the network. What’s even pissing me off? Moore is now I can’t go back to the original network because it says that it can’t connect to it either. 

I hoping somebody here can give me some insight without a flood of misdirection because this is the stupidest bunch of bull I’ve ever seen. I’ve even tried moving my cell phone to the same network that I’m trying to add the Sonos to and that also didn’t work. Now I have the Sonos app asking me to restart the devices and restart my firewall. Now that I’ve knocked my entire network off-line for two speakers which didn’t do a thing because now I have a message on my app saying we couldn’t connect to your products. Please try again later.
