Why not use the C2000T as a wired-only router (disable WiFi) and use your R7000 as a WiFi AP?
You mentioned that you want full speed in the den, which means you may need a quality network switch in there. Then connect your devices to that switch. You can connect the R7000 to either the switch or the modem, your choice. The switch and modem need to be wired together, of course.
You may not need a switch if the R7000 is capable of full gigabit speeds, but you mentioned that it was only capable of 850Mbit on the WAN. Whether that limut applies to LAN to LAN traffic, I dunno.
No, it only hits it's head across the WAN port. LAN-LAN speeds are fine. And I *wish* it would do 850; it is maxing out at 500. The RT-87U is the router that has been reported to hit 850 across the WAN port, but I don't have that router. I considered purchasing it, but there are wide spread reports about reliability issues with 5ghz connections.
As I mentioned in an earlier post, I had the C2000T handling the ethernet connections and the R7000 handling wifi, but the R7000 kept crashing. I'll be working on this configuration more, though, as I think this is about the best solution for the hardware I have, and it doesn't look like any consumer grade alternatives would be adequate.
