I just recently had the g1100 router installed and I bought the previous router, the Fios Quantum Gateway. I'm using the g1100 as my main router in room 1, but in room 2 I need a ethernet connection but I only have a coaxial connection (I can't use a WiFi extender it is too far). So would I be able to us the Quantum Gateway as a router in room 2 if I plug it into the coaxial port? If I can do I have to modify anything in the settings?
