I recently purchased a google nest wifi router and want to set up my modem vr1600v. The modem is already set up (as we were using this for almost year).
I have tried as advised below but it still does not work 
, Any suggestions?
Google site suggests this:
The best solution to double NAT is enabling Bridge mode on your modem/router combo.
Log in to your router or modem/router combo and find its settings to enable Bridge mode. To access your router’s settings, you might have to open an Internet browser, and enter your router’s IPaddress in the address bar. Details vary depending on the device. Many ISPs and manufacturers provide instructions on how to do this.
