Well, I did get out for a walk around Quarry Lakes after lunch. Now I'm settled in to watch the Super Bowl, although I don't have any dog in this hunt. I decided to take the computer into the living room. To my annoyance, it would connect to the home wireless network, then disconnect. If I unplugged the AC power, it would connect, and then disconnect when I unplugged the power. If it sat flat on the coffee table, it would connect, but if I propped the back up slightly (a configuration I find easier for typing) it would not. I assume it must have something to do with the wireless antenna. Anyway, I eventually found a configuration where I can connect. Don't know how long it will last, though.
