How to use my N600 router/modem C3700 as a modem only (choosing "no" to router mode did not work)
I have an N600 Router/Modem and an R7000 NightHawk Router. I want to use the N600 as a modem only and the NightHawk as my sole router. So, I chose "off" in the router mode on my N600 but it will no...

disconnect the R7000 and any other devices from the c3700. For good measure, I'd reset the R7000 back to factory as well.
Switch it over the modem only mode. It should reboot. If it doesn't reboot, then power it down and back on.
then hook up the R7000 to it with the r7000 powered down (and the r7000 needs to be in router mode).
then power up the r7000. Let it fully boot.
then try to setup the r7000.
don't hook anything else up to the C3700. In modem only mode, it only gets a single public ip address from the ISP. If multiple devices are plugged in, it'll cause issues and won't work properly.

Was doing more research, I don't see a modem only setting for the D3600. You can disable the dhcp server and the wifi on it. then just hook only the R7000 to it.
