I'm living in a basement suite. The landlords upstairs have internet through cable and told me I'd also have it, but all I have is the outlet where a TV type of cable would normally go. Can I just buy a cable modem from a store, or do I have to get it through a cable company? Do I have to pay the cable company money, or should I be able to just hook it up and use it? From what I understand the cable company charges you for the IP they give you because the number of IP's you have is related to how much bandwidth the system gets. Would the two modems be able to run on the same IP address? A few days after I moved in, the landlords left a few things outside my door that I think they wanted me to use to create an internet connection with, but I have no idea how they expected me to use it. They left a wireless router, a small length of TV type cable and a wireless card without the required installation software. Is there a way I can use any of this to get online without a cable modem?
