RBR40 and Chromecast Audio Device
I have an Orbi system setup in AP mode with a FIOS Gateway (wireless antennae disabled). I've successfully set up multiple chromecast audios and groups in the past. I have a new soundbar with chromecast that I just cannot get to work. After messing around for a long time with various settings based on different posts here, I was finally able to get the soundbar hooked up. I believe what worked was using a method from another post putting it on the guest network with the same password. However, it only works on my iPad. I cannot get any android device to work. It will see the soundbar, but can't communicate. I've also tried methods seen elsewhere for chromecast issues, including turning airplane mode off and on (on the android devices) during setup.
I've confirmed that it's on the 2.4 part of the guest network. But I'm at a loss as to whether there's any additional settings I can change. It does appear that most other devices are on the 5, but I was under the impression that all the devices should be able to connect to devices regardless of which one they were on, right?
If anyone can point me in the right direction, I'd appreciate it. I have limited time to change individual settings and reboot since I've got remote learning going on all the time. I"ve turned off an on a lot of different settings based on other posts.
Thanks for any tips in the right direction.
If it's helpful my current setup after following multiple other posts is:

This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktopI would try option #2 first, then #3 next.
Thanks for the reply.
I think I may have explained it poorly. I believe I'm already connect via method #3. I attempted #2 unsuccessfully a few months ago, though I'll try it out after remote learning is done.
