WPA/WPA2-Enterprise: Also called WPA/WPA2-EAP (Extensible Authentication Protocol). In addition to
device-based authentication, WPA/WPA2-Enterprise enables user-based authentication via IEEE802.1X.
The TAP-125-U-W-X-Z (YYYYYYYY) can support three EAP methods: EAP-TLS, EAP-TTLS, and EAP-PEAP.

For security reasons, you should NOT set security mode to Open System, since authentication and data
encryption are NOT performed in Open System mode.
WEP
According to the IEEE802.11 standard, WEP can be used for authentication and data encryption to maintain
confidentiality. Shared (or Shared Key) authentication type is used if WEP authentication and data encryption
are both needed. Normally, Open (or Open System) authentication type is used when WEP data encryption is
run with authentication.
When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be specified as 64/128
bits, which is actually a 40/104-bit secret key with a 24-bit initialization vector. The TAP-125-U-W-X-Z
(YYYYYYYY) provides 4 entities of WEP key settings that can be selected to use with Key index. The
selected key setting specifies the key to be used as a send-key for encrypting traffic from the AP side to the
wireless client side. All 4 WEP keys are used as receive-keys to decrypt traffic from the wireless client side to
the AP side.
The WEP key can be presented in two Key types, HEX and ASCII. Each ASCII character has 8 bits, so a 40-bit
(or 64-bit) WEP key contains 5 characters, and a 104-bit (or 128-bit) key has 13 characters. In hex, each
character uses 4 bits, so a 40-bit key has 10 hex characters, and a 128-bit key has 26 characters.
