Just upgraded to 1GB speed and now have the following setup with the Quantum Router setup as a bridge (disabled wifi, dhcp...):
ONT -> WAN Google Wifi LAN -> LAN Fios Quantum Router
The Quantum still has the coax so it can feed my two set top boxes.
All seems fine and I can see all devices in my house, including my set top boxes, through the Google WiFi app.
However, now I notice that when I try to watch live TV on the Fios app, I only get a limited number of channel options as it says I am not connected to my home network.
Has anyone experienced this and found a rememdy?
I imagine the solution is to enable wifi on the Quantum router and connect to that network only when I want to watch live local TV from the app. Hoping that is not the case though.
Hope to hear from some other options.
