If I don't make any sense sorry, not an expert. In your setup do you still have a stand alone cable modem? If so, when you connect a computer directly to the cable modem can you access the Internet? If your new setup is also replacing the cable modem do you have to log into your account before it will work? I know with Frontier DSL when I replaced their unit with my own DSL Modem I had to log into my Frontier account through the modem before I could actually use it to access the Internet.
