Assume you're running the xfinity modem in bridge mode with the wifi disabled?

That Netgear is a nice piece. The world of wifi everything is really stressing out most consumer routers, but a good 6 system should be fine.

I do know of a friend that had an issue with his local xfinity whereby some security software at their end didn't like some device he had on his network (an older airport he used for streaming) and identified it as a possible dns attack threat and kept whacking his ip with filtering that would crash his network. No one locally could solve it, but he's a cellular consultant to investment banks and was able to get thru to top level engineers at Comcast that solved it for him. You or I would get nowhere.
