A:Answer Yes, Google Nest WiFi mesh system is compatible with your router, but it is recommended to connect the Nest WiFi router directly to your modem's WAN port as your primary router to establish your Wi-Fi mesh network. If you connect Nest WiFi router to your Fios Quantum Gateway router, then both routers will broadcast their own private networks. This is called Double NAT and it will likely cause connectivity issues when port forwarding and gaming.
