Upgrading Firmware

[AJ290]

It's my understanding that firmware upgrades to any cable modem are provided via the ISP.
In my case, that's Comcast/Xfinity. Thinking of going with the C7800 modem/router combo.

Two questions:

1)  will Comcast support know what I'm calling about when I ask for a firmware upgrade?  I'm leery of dealing with some kid in the Phillipines upgrading my hardware.
2)  Being that the C7800 is a combo unit, is there a separate firmware upgrade for the router?

Thank you.

when comcast provisions the device it'll update the firmware with their provisioning. the "router" portion of this will update with their provisioning. Thats the problem with combo devices is that the ISP controls the firmware for the whole device and not just the modem functions
