Simple wireless networks require WEP keys or a WPA/WPA2 preshared key/passphrase, or may not have any security at all. More-advanced wireless network security can require one or more certificates and an authentication server. If the network requires a certificate and you do not have it, then fill out the certificate request form provided within the Wireless Setup Utility and follow the procedure of your organization in requesting a certificate for network access.
The following is a list of supported types of wireless network security and their requirements:
WEP key (up to four keys may be required)
Default WEP Transmit Key (if more than one WEP key is configured, this specifies which one to use)
Preshared key
Encryption (AES or TKIP)
