After 5 transfers and 45 minutes, we all came to the conclusion that my equipment is old (just installed in November 2014) and we should upgrade to a single X3 Router, which is their newest setup that does cable modem, wifi and Home Security router.
I'm hopeful this is right, or I'm going to be super disappointed.
If anyone from XFINITY/COMCAST can confirm this is the right path, I'd appreciate it.
