my customer-own modem appears to lose its provisioning/activation at least once a day, and that is for all of my devices, which get routed to the Xfinity "Let's get started" screen at "https://register.be.xfinity.com/activate". you could effectively say that my modem is stuck in "ground-hog mode".
other Comcast Xfinity customers also appear to have this same problem which has been reported here: "http://forums.xfinity.com/t5/Your-Home-Network/Modem-loses-provisioning-asks-for-reactivation-every-...", and here: "http://forums.xfinity.com/t5/Your-Home-Network/Xfinity-activation-is-required-every-day/td-p/3059193" although i have no idea if the issue has been resolved for them.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
