T-Mobile Gateway kdv21 and Netgear c6300v2

[ljones86]

I used a coax to ethernet adapter to connect my Netgear Nighthawk to the T-moblile Gateway.  I wanted to use the Gateway as a modem and create a LAN via the Netgear NIghthawk.  How do I get the Nighthawk to broadcast internet.  The Nighthawk creates a LAN and I can connect my old printer and computer using this LAN but the LAN is not connected to the internet from the Gateway.  Anybody got a solution to get the Nighthawk LAN connected to the internet from the Gateway?
