We're having AT&T Fiber installed at the house, and the tech informed me that he's getting a "short" reading and that the CAT5 wiring in the house is bad. The house is 7 years old, so it's not covered by warranty. What do I do here? Am I SOL? I guess general solution would be to have an electrician come out and try to pull new CAT5 cable from the ground floor up to the main comm box?
