I have a customer who married a guy and he likes to build computers. Yay. He also likes to tinker with the network. Yay. I wired the place before he was even in her life and eventually, I got a call saying that the WiFi & hard wired network in the Master Bedroom as well as most of the house, wasn't working- he was convinced that it was caused by a mouse chewing through a cable in a wall. Right. OK, I went there one evening, but it was too dark and they were going out, so I went back the next day and checked into it. I found that he had unplugged EVERY ethernet jumper in the enclosure between the switch and punch down modules, located in the basement- he even unplugged the power cord for the switch. I reconnected everything and went upstairs to check the WiFi- it was limited to the space covered by the router, so I looked at that- he had bought an Asus gaming router just before the wheels fell off and before I left the previous time, I got the model number so I could check into it. It has a fallback WAN port- guess where he connected the ethernet cable that feeds the network switch in the basement......

I told my customer and she said "Typical".
