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 not communicate the internet to my NightHawk Router.
If I use the N600 with the router mode "on," I can successfully plug the NightHawk into the N600 and use the NightHawk to create a second network. In that scenario I have two active networks.
So, I have two questions. First question: If I have two networks as described above are they as powerful as having just one network?
Second Question: Second question: How do I get the N600 to actually work as a modem only?

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.

Where "off" was actually spelled "No"?

> as having just one network?Define "powerful". If the C3700 and the R7000 are close together,
then they might interfere with each other more than reinforce each
other. And, communication between devices on the different subnetworks
can be difficult.> [...] How do I get the N600 to actually work as a modem only?
Did you contact your (unspecified) ISP? Cable-TV providers can be
fussy about (or fearful of) different (or multiple) devices connecting
to your cable. You may need to provide a MAC address (for the R7000) to
your ISP.
Another option would be to keep the C3700 in modem+router mode, and
configure the R7000 as a wireless access point. This might be more
useful if you can separate the two devices.Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual. Read. Look for "Use the
Router as a Wireless Access Point".
> I don't see a modem only setting for the D3600. [...]I'll bite. Who was asking about a D3600?
There should be a NAT mode feature with in the C3700's web page, probably under Advanced tab/Advanced settings/Router or modem mode? If you find this settting, disable the NAT mode and that should set the c3700 up for modem only mode.
Review the user manual for modem only mode information and location of this feature in the modems web page.
