I have an internet provider WiFi router/modem at one end of my house, and the R7000 at the other end. I originally set it up as a sub LAN (internet port on R7000 connected to Lan port on on WiFi router/modem). I though this config would separate the guest phones/portables from my "work" Lan. I also have a Windows desktop connected to the R7000 via Lan port. In the past, this all seemed to work fine as I could "share" across the two Lans (router/modem DHCP range 192.168.254.x, R7000 DHCP range 10.0.0.x). Initially the sharing worked intermittantly, but now not at all... especially the network printer HP 2035n. BTW, the R7000 has an IP address of 192.168.254.59 assigned by the router/modem.
So I thought I could just turn off DHCP on the R7000, and the router/modem would assign IP's sharing would be seamless and all would be well. No joy ;( Now the desktop connected to the R7000 had no internet access, and couldn't even talk to the R7000 to manage the configuration (I was able to connect wirelessly from a laptop).
I looked online to find examples of how to configure my situation with a single DHCP (a single network). No joy.
After attempt 1 (above) I tried to configure the R7000 to provide DHCP in a subrange of the 192.168.254.x, which did not conflict with the DHCP range of the router/modem. The configuration manager on the R7000 wouldn't let me choose a LAN ip (of the router I guess) of 192.168.254.210 and DHCP range of 192.168.254.211-230.
I'm a retired software engineer, but obviously not a network engineer.

Some of us may not know which end of your house is the "work" end, but, either way, it can be tough to isolate much with only two routers. (And it's seldom worth the bother.)

I don't see how. With two LAN subnets, I'd expect to need to do some extra routing configuration to get data to move between them. Typically, that would be done by specifying a static route on the outer router.

There's more to it than that.

"online" is a very big place, with many examples of many things.

Also a bad idea.
If you'd like to have one big LAN, with one subnet and easy sharing, then the usual approach would be to configure the inner router (R7000) as a wireless access point. Astoundingly (perhaps), this is covered in the R7000 User Manual. (Although the pictures were better before the latest revision.)
