I had to leave then to take my daughters to the dentist (another random day off; similar to my random internet connection). They told me to call back and they'd walk me through some things to check.
When I got home, it was working again. I called them anyway, and they walked me through the secret sequence of powering things off and on to get my wifi working again. Of course, it all works now. Kind of like going to the doctor and your symptoms stop.
But I don't trust it. Perhaps I shouldn't write it out loud. It might see me, take offense and drop again. The computer guys think I really didn't have the right power down/up sequence, but we'll see. Random acts of confusion and mayhem seem to be all part of the computer world. That's why they'll never take over.
And people call me sensitive.
