The PlayStation 3 supports a wired Internet connection when connecting to the PlayStation Network. The PlayStation Network houses all online PlayStation content, including the PlayStation Store, PlayStation Home and a variety of streaming media service such as Netflix. Built in to the PlayStation 3 is an Ethernet port, which can be used to connect to a broadband modem or router. Ethernet connections require less set up and are generally more reliable than wireless connections.
Press the "Power" button on the front of the PS3 to turn it off if it's on. Connect one side of the Ethernet cable into the "Ethernet" port on the back of the PS3 and connect the other side into the "Ethernet/Internet/WAN" port on the broadband modem or router.
Press the "Power" button to turn the PS3 on. The PS3 main menu, referred to as the XMB, will open. Press the "PS" button on the center of the PS3 controller to turn it on. Press the arrows on the directional pad or use the analog stick to move to the "Settings" icon on the XMB.
Select "Network Settings" and press the "X" button. Scroll down to "Internet Connection" and select "Enabled." Scroll down to "Internet Connection Settings" and press the "X" button. Select "Easy" as the connection method. The PS3 will automatically search for a wired connection.
Press the "X" button to save the settings. Select "Test Connection." After the test completes, the PS3 will be connected online.
