No matter what connection i have i can't connect to the internet on my ps3 how do i fix that?

Have you tried this Sony PlayStation support site and listened when they said that you could not connect without High Speed Broadband Cable or DSL and that Dial-Up connection is not supported and that you could not connect using the USB ports. That means you won't be able to connect using USB wireless adaptors or Cell Phone USB adaptors with the PS3 system. The system PlayStation has to provide support has helped millions to connect to the internet. Use the related link and give it a try after you have a Broadband or DSL internet service and the connection devices.
