The laptop usually runs over Wi-Fi, but today I had it plugged in a 
couple of times. I also had it connected via Wi-Fi to my cell phone 
while away from the house, and then via Wi-Fi to another modem while 
testing that the other modem was working. So, it makes sense that it 
would show up when I had it back home and plugged it in to CAT-5 while 
in my office, neglecting to remember that I usually only use it via Wi-Fi.

Thanks. I think I can call this one "fixed".
