XB7 and google wifi router

Recently i switched over the XB7.  I have the google router plugged in.  For some reason, destiny and xbox are not working properly and i dont think speeds are where they should be. 

Im thinking there may be a double NAT issue. But when i tried to switch the XB7 over to bridge mode it completely killed the internet and i see signal.

Is there a particular port i should have the google router plugged in to?
