How do you delete network setting in ps3?

To delete network settings on a PS3, go to the "Settings" menu from the XMB (cross-media bar). Select "Network Settings," then choose "internet Connection Settings." From there, you can either choose to configure a new connection or delete the existing settings. If you want to reset the entire network configuration, you can also go to "System Settings" and select "Restore Default Settings," but this will reset all system settings, not just network settings.
