Funny you say that. We had someone in a remote office complaining of neverending WIFI problems, but never reproducable. None of the coworkers mentioned any problems. All network statistics said everything fine. One day I happen to be in the neighbourhood so let's take a look.
Turns out the line was upgraded by the phone company, but the old modem never removed. So there was a new phone line connected to a new modem connected to nothing. Next to it a literally crumbling phone line, an old modem thrown on the ground and buried under a mess of boxes and overheating, connected to their core router. Monitoring was a mess of statistics from the old and new system thrown together, so nobody noticed for over 2 years.
Why she was the only complainer at that office, I will never understand. But she stopped complaining that very day.
