Multiple Orbi devices with Router set up use AP question

Greystorm64 You do not need to turn off DHCP, DNS, or configure anything on Orbi or the satellites.  Just switch Orbi to Access Point mode and choose whether to set Orbi's IP address manually or have Orbi obtain an IP address via DHCP from your new router.  Your Orbi will continue to provide the same WiFi coverage as before. Your new router should assign IP addresses to the satellites as well.  I use DHCP IP address reservations in my third party router for the Orbi "router" and my two satellites.  That way I always know where to go to log into them.
