How come when I set up the Jersey Shore computer as the Host, I can't connect to it using the cable modem? The shore computer has dialup, we have a cable modem here. I had my father sign online down there, while I tried to connect up here using the IP Address of the shore computer, my user name and password, and TCP/IP connection. It didn't work. But if I chose Dial up as the connection for both computers, it connected flawlessly. Any ideas?
