Said much better. Once again, I am "too literal". Every router (of any brand) can be attached to an existing router/satellite (of any brand) and will do what it is supposed to do: it will set up its own IP subnet and assign IP addresses to anything that asks for one. Just today, I attached an Orbi RBR50 yellow (WAN) port to an existing Orbi RBR50 LAN port. Worked fine, except that it's an irrational thing to do. A computer attached to my 2nd Orbi surfed the web just fine. Did email just fine. BUT... when I wanted to access a printer on my primary Orbi - no dice! Computers on my regular Orbi have no idea how to reach computers on my 2nd Orbi.
I am thinking here of those people who post questions about , "How can I provide access to (tenants, renters, children, etc.) without letting them access my main network?" Any old WiFi router would do the trick (including the RBR40).
If the question was meant "the other way", "Can I attach an RBS850 satellite to a CBR40 router, "no way in hell".
