"WEP" stands for wired equivalent privacy. It is an added layer of protection for a wireless network. To connect to a WEP key-enabled network, you need to select the network's SSID (service set identification, a network's public name) and enter the WEP exactly as it was entered into the router. An unknown WEP or one that is incorrectly entered will prevent you from connecting to that network.
Aspects of a WEP Key
The WEP key is the password for a wireless network. These passwords help protect a network by keeping unwanted users from being able to connect to a private wireless router. A WEP key can come in four formats: five letters and numbers, 13 letters and numbers, 10-digit hexadecimal, and 26-digit hexadecimal. Though WEP is considered to be a flawed method of securing a network, it is still widely used in many home wireless networks.
Locating the WEP
The WEP key is typically written somewhere on a wireless router. If it isn't written on a wireless router and you want to change or disable the WEP key, you can change the router's settings by entering "192.168.0.1" in a web browser.
PSP Wi-Fi
The PSP connects to the Internet via a Wi-Fi connection. To connect to the Internet, the PSP must be in range of a wireless router so that it can receive a signal and connect to the Internet. Once that is established, simply find the network SSID to which you wish to connect.
Other Internet Security
The WPA key is another common security key. "WPA" stands for Wi-Fi Protected Access. In home networks, it is referred to as "WPA-PSK;" "PSK" stands for Pre-Shared Key. The WPA key can range from eight to 63 characters in length, or exactly 64 hexadecimal characters. Unlike WEP keys, WPA keys require encryption. Encryption is handled by one of two protocols: Temporary Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES). Some routers do not support AES, so TKIP is the most common type of encryption you will come across with WPA.
