Pro tip: a bad barrel connector on a 6 foot run ate 4 hours of my Tuesday
Two weeks ago I got called out to a house in Mesa for a simple internet drop, one room, maybe 40 feet of cable, easy money right? Wrong. The signal kept dropping every few minutes and I swapped the modem, the splitter, and even re-terminated both ends twice. I was on site for 4 hours on what should have been a 45 minute job, and the whole time the homeowner is standing behind me asking if it's the provider's fault. Turned out the barrel connector in the wall plate was loose and the center pin was barely making contact, so every little bump killed the signal. A $1.50 part cost me a whole afternoon and made me look like a rookie in front of a paying customer. Now I keep 10 spare barrels in the van and I check every wall plate first before I touch anything else. What's the dumbest cheap part that has ever wrecked your whole day on a job?
