Plug the small, rectangular shaped USB input on your Wi-Fi link USB adapter into any available USB input on your PC. The USB inputs on your PC are also rectangular shaped. The Wi-Fi link adapter connects to your PC the same way a flash drive would.The PlayStation 3 has built-in wireless network capabilities so no device like the Wi-Fi link is needed on the console itself. Instead, the Wi-Fi link USB adapter is designed to take your computer's wired network connection and turn it into a wireless connection that the PS3 can then use to get online.
Turn on the Sony home video game console.
Select "Settings" and "Network Settings."
