You do not have a cable "internet" connection, you have a cable TV connection. The FORT will give you a "modem kit" that has the necessary cables and a splitter along with the instructions on how to connect everything. You need to plug your laptop into the cable modem with an ethernet cable unless you have your own wifi modem to connect to the cable modem for wireless, which is what we do. Actually that is how I am responding right now.
Enjoy the FORT.
