Configure R7000 to take internet from another router

Hello. I have a home network with an R7000 as the main router. There are many devices and home automation configured to it. I have another router that is used exclusively to provide internet service (it is a 4G router). I can see my devices correctly but I am not able to provide internet service to my R7000. 

I found this post ( R7000 as access point )in the forum, but it doesn't help me since I think (I'm not sure) that if I put my R7000 in access point mode, it will no longer manage the IPs. And I don't want that since every time I change my router (I mean the 4g router for a different one), I would have to reconfigure all my devices every time. Below I put a diagram of how I have my network set up. Everything works fine except internet service. How can i fix this? Another fact to keep in mind is that the connection between the 2 routers is LAN to LAN.

    If the tplink is truly in passthrough/modem only mode, you need to go tplink---->netgear---->switch.

    You have it going tplink---switch----netgear.

      But my switch switch dont have any ip or configuration. So it should not affect the configuration, right? I am new into Lan design. what should i do ? 

      Must the 4G router and R7000 be connected directly?I cannot move the 4g Router because it is the only place where I have coverage, and the R7000 is better for me if it is in the living room due to space issues. If you explain to me a little about how a switch can influence, I would appreciate it, because I thought that since it is a device without IP or configuration, it could not affect the network.

        Problem is that if the tplink is truly in passthrough/modem only mode, the isp only assigns 1 public ip address. And if you're putting a switch next, then one of the other devices attached and not the router can get that public ip address. 

        The route normally takes that public ip address and assigns private ip addresses to devices on the network (simplified explaination). 

        If the device assigned the public ip address isn't handling hdcp/nat (like the router does), then nothing else can connect to the internet.
