Orbi's are junk
Bought a set for my mum. The first few versions were alright, but they doubled down on all the wrong things. You have almost no control over the AP config in the firmware. You have to install the crappy app, which does not let you configure much either, and it if decides to grab the same address as something on the existing network, god help you, and it will knock itself and your network offline.
Ubi's AmpliFi line were better if you need mesh coverage, but also seem to be in a tailspin as far as updates to either the firmware or the product line. I have been using Nano HDs on each floor in standalone mode (I hate Ubi's "controller" software) and a 3rd party PoE switch. Setup is pointlessly stupid so I can't recommend it, but it is at least boring and stable once configured, and you can update the firmware.
The Orbi's like to park themselves on top of adjacent wifi signals and will just disable large chunks of their 5g bands instead of moving to open channels. They also like using 2.4g links, killing performance even on dual band gear. You are pretty much stuck with whatever it wants too do, as there is no "advanced mode" setup for things you may be used to seeing. This can also cause headaches if you have gear with a radio chipset that is picky about band/WPA/SSID settings.
