The crack Comcast tech, who really did know his business, has come and gone. The problem was not just mine but also affected the neighborhood, and it might be 72 hours before all is well again. However, he also found a problem with the outside connections for both TV and Internet, and he fixed that. Maybe I'll be able to have a connection without interruption. I hope so, not that I need to be connected. It's just a convenience, that's all. Trust me.
