Things You'll Need
Instructions
Connect one of the Ethernet cables from the dial-up modem to your computer, and the other from your computer to the Ethernet port on your PlayStation 3 console.
Power on the PlayStation 3 console and launch your computer's dial-up connection. Although an Internet connection will begin to transfer data from your computer to your PS3, you will need to configure the Internet settings on your PlayStation 3 before the connection is complete.
Scroll over to the "Network Settings" icon on your PlayStation main menu. Scroll down to the "Settings" menu and select the "Internet Connection Settings" option.
Press the "X" button on your PlayStation controller as the "Enter" command. Select the "Wired Connection" option on the next page and wait for the console to detect the dial-up connection. Once it has detected the connection coming from your computer, it will take you back to the PlayStation main menu.
