It worked Sunday early morning. It didn't work Sunday mid-morning.
I played with it. Encouraged it. Talked firmly to it. Tech support was willing to talk firmly to it, but it wasn't taking calls. It wasn't talking to anybody.
So I'm not ignoring you, it's the cable modem. The plan is to pick up a new one tonight on the way home.
In the meantime I actually had time to read, and (gasp!) finish a book. Maddie Hatter and the Deadly Diamond by my buddy Jayne Barnard. It's a fun steampunk romp. I'd read more of it.
