The Sony PSP hand-held video game system has wireless Internet capabilities. You can use the wireless Internet on the PSP to download demos, videos and even entire PSP games from the PlayStation Network. Before you can access any of these online features, you'll have to configure your PSP to connect to your wireless router.
Turn your PSP on. Press "Home" if your PSP automatically boots up a game. Set the WLAN switch on the lower-left side of the PSP to the "On" position.
Navigate to the "Settings" section of the home screen. Highlight "Network Settings" and press "X."
Choose "Infrastructure Mode" and press "X." Highlight "New Connection" and press "X."
Press "X," create a name for the network, highlight the "Enter" key and press "X." This name does not have to be the same as your network's SSID: you can name it anything you like.
Select "Scan" and press "Right" on the gamepad. Choose your wireless network from the list and press "Right" again. Choose the type of wireless security your router uses, if any, and press "Right." Enter the network password. Highlight the green "Enter" button and press "X." Press "Right" three times, then press "X" to save the settings.
Highlight "Test Connection" and press "X" to test the connection to the wireless router.
