I upgraded my WiFi from one that had a router and modem combined to one where they are separate. Will this Orbi works with that configuration?
Yes, but you may have to change the settings on your Orbi router.
That depends on how you have it set up now. For example, if you had to put the Orbi into access point mode to work with the other router – that's common practice – you may need to put the Orbi into router mode.
