AP Mode Vs Router Mode—both seem to work
Just installed a new R7800 router. Set it up initially using default settings. I connected it to my modem with an Ethernet cable. All works as expected. Although…my modem is also a router. So what I ...

Yup. Try more things. For example, file sharing between systems on
the "192.168.1.*" subnet and systems on the "10.0.0.*" subnet. Or
anything which requires port forwarding to the inner subnet
("10.0.0.*").
Cascading routers doesn't wreck everything, but it does wreck many
things. If you don't notice or care, then it may not matter. If all
you ever do is use a web browser accessing the outside world, or an
e-mail client, or the like, then you might never have a problem. As
soon as you do anything on the inner subnet which involves a server
(like, say, file sharing, or a web server, or some games), then you can
expect to run into trouble.

Because many things work better (or more easily) if all your client
devices are on one subnet. Search these forums for terms like "double
NAT", and see some of the trouble people get into when they cascade two
(or, in a few cases, more) routers.

Thanks antinode. What you say makes sense.
In fact I only have devices with which I'm unlikely to want to communicate on the 192.168.1.** subnet—Apple TV, a television, and a PVR. All my computing devices—Macs, iPhones, iPads—are connected via WiFi to the 10.0.0.** subnet.
Nevertheless I see no reason not to go with your recommendation to use AP Mode, and keep everything on the one subnet.
