Setting up a wireless Internet connection using the [Easy] settings
Before you begin:
Ensure that the settings for the wireless access point (usually a router) are correct and that its power cable is properly connected. If it is battery-powered, check that the batteries have not run out.
Ensure that the Ethernet cable is not connected to the PlayStation 3 system. If the Ethernet cable is connected, the PlayStation 3 system will automatically attempt to connect to the Internet via a wired connection.
Access the XMB Menu and choose [ Settings] > [ Network Settings].
