Things You'll Need
Instructions
Plug an Ethernet cable from your router into the back of the PlayStation 3.
Power the PlayStation on. Navigate to "Settings," then "Network Settings" using the PS3 controller.
Select "Internet Connection Settings," then "Yes." Select "Easy." The PS3 will detect your wired Internet connection.
Choose "Test Connection" to ensure the wired Ethernet connection is properly working. If successful, a confirmation message will be displayed. Save the settings and and exit back out to the main PS3 menu. Once configured, your Internet connection will not only be faster, but much more reliable.
