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.

WPA/WPA2-Personal
WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method.
WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i.
The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is
regularly changed so that true session is secured.
Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security
mode of some wireless APs and clients as well. The IE-WL-VL-AP-BR-CL also supports AES algorithms in WPA
and WPA2 for better compatibility.
Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (
Pre-Shared Key
), provide a simple way of
encrypting a wireless connection for high confidentiality. A
Passphrase
is used as a basis for encryption
methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as
possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security
reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.
