Orbi RBR20 with AT&T internet

[ddjeff]

Sorry if this has been asked before but I just got ATT internet and I noticed that my orbi (when plugged into the provided att router/modem) shows the RBR as a magenta color and the RBSs as green. All firmware is updated. The main screen of my app also says it’s offline but I have internet connection which is weird.

I’m not sure why it’s doing this but I’d like to just use the att box as a modem and rely on the orbi as the router. Is there a way to make that happen with att?

Sorry not real knowledgeable on all this.

Any of those 3 should work.

What I'd recommend? it'd be based on your capabilities. 

If you don't use the orbi's parental controls or other features, just put it in AP mode. 

If you use them. Then try the passthrough or dmz option.

its because att installs modem/router combo devices. 

it puts you in a double nat. https://kb.netgear.com/30186/What-is-Double-NAT

options? 

1. put the orbi in access point mode

2. put the att router in passthrough/modem only mode

3. put the orbi in the att's devices DMZ

Ok thanks, which would you recommend if those three? Or did you mean try them in that order?
