The funny thing is that he's done this twice in a week after having never done it before after having the service for several years. Maybe I should write all of the settings out and tape them to the router. I have something similar at home, with a sheet taped to the wall behind the router with all of the setting information just for cases like this.
Ironically, he did this just as I was sending my (I hope) last e-mail of the night before turning in. However, if I hadn't fixed it tonight, I still would have had to fix it tomorrow morning.
