Instructions
Launch an Internet web browser on a computer that has a network connection with your wireless router. The type of browser does not matter.
Enter your router's IP address in the address bar of the web browser and press the "Enter" key on your keyboard. The default IP address varies by the brand of router. If you don't know your router's IP address, you will need to check its manual.
Log into the router's control panel using an administrator account. If you did not set up an administrator user name and password for your router, it should be using the default administrator settings. If you do not know these settings, you will need to check your router's manual.
Open the "Wireless" network settings on your router's menu and navigate to the "Security" section. If you have set up a security password on your router, the information should be displayed here.
Write down the password listed next to "Key 1" under your WEP settings. This will be a combination of letters and numbers. There will be 4 keys listed, but you will only need to use Key 1.
Enter WEP Key 1 into your PSP's wireless configuration to connect to the wireless router and establish an Internet connection.
