Well, I still have no resolution to this problem. I have the cck disconnected except when I want to download a movie. To download a movie, I connect the cck to the router via Ethernet, download and watch the movie, and then disconnect the Ethernet. Usually, I have to reboot several boxes to get whole home to work again. I think I will call me ISP (Entouch), just in case they have heard of such a problem. I am eve considering changing ISPs, but I cringe at having to change my email address.
