A while back I was working for a woman who had an unusual small office building (I'm pretty sure it's a big converted house), who shared the place with a small law firm's branch office. They decided to split the verizon bill and share internet. Of course they had no clue how to do this, so they managed to find me of all poor schmucks. After misery with verizon, I got them set up with a nice wireless network.
A few months later I'm called back - this lawyer is moving his office to another room in the building. So my task is to move the damn computer? Go figure
Either way, it turns out as I had expected - wireless struggles through two walls. So the woman then wanted me to wire up the basement and get ethernet over there. Suddenly I'd gone from simple tech to network jesus to electrician and wiring expert
Despite my daily calls to her, I haven't been back since, so I assume they're getting along just fine
