I have a cable ISP for my cable internet. They've supplied me with only one cable modem, which I use to directly connect to the internet for one computer. My roommate also has a computer, which he brought another cable modem home one day. He has a television in his room, which runs on cable. He plugged in that cable to that cable modem and he gets free internet access. Would this be considered stealing from our isp? Because we have everything under them (cable internet, tv, etc.). Would it be technically stealing if we're using a tv cable (we're also paying them for the tv bill). And does this slow down my modem in a way? BEcause we are under the same household. I want to know the legal matters before I consider allowing him to do it again.
