Flat earth rocket guy was low-key kind of awesome. Taught himself how to build rockets and had a few successful launches. No rocket program has ever had a 100% success rate. Unfortunately he also suspected that the world was flat.

Yeah it sucks. As often as I see it I would be willing to guess its not something that inspections for.

I honestly don't have any clue why this seems to be such a common practice. I blame HGTV, all those shows never talk about cat6 or coax cables and in this day and age its just as important as power/heating.

Edit: Sorry I didn't even answer the question. Even if the exterior cable was intact and you hooked up a router to it. It still wouldn't work unless the service was activated for that address.
