SSID
You can find your SSID on your wireless router. This is your box that connects you to the Internet and will have an antenna on it. It will typically be on a sticker on the bottom of your router, but if you have trouble finding it, refer to your router's manufacturer for further assistance.
Security
Wireless connections have a few security options. When connecting your PSP to your SSID, if it requires you to enter a password, then your network is secure. The two options that may come up for passwords are the hexadecimal wired equivalent privacy (WEP) option or the personalized WiFi protected access (WPA).
Speed
When connecting to your SSID you need to understand that it is a wireless connection. Wireless connections are not as reliable as a hard connection and your speeds and connectivity can vary.
