WPA Encryption When "WPA-PSK" authentication method is used, the newly proposed TKIP (Temporal Key Integrity Protocol) or AES encryption schemes are applied. WPA Pre-Shared Key Select "TKIP" or "AES" in the WPA Encryption, this field is used as a password to begin the encryption process. 8 to 63 characters are required. WEP Encryption When "Open or Shared Key", "Shared Key" or "Radius with 802.1x" authentication methods are selected, traditional WEP encrption is applied. When "WPA" or "WPA-PSK" authentication methods are selected, you still can set WEP encryption for those clients that do not support WPA/WPA-PSK. Please note that Key Index for WEP key is limited to 2 or 3 when both WPA and WEP encryption are supported at the same time. 64/128-bit versus 40/104-bit The following section explains low-level (64-bit) and high-level (128-bit) WEP Encryption schemes: 64-bit WEP Encryption 64-bit WEP and 40-bit WEP are the same encryption methods and can interoperate in a wireless network. This level of WEP encryption uses a 40-bit (10 Hex character) encryption scheme as a secret key, which is set by the user, and a 24-bit "Initialization Vector" scheme, which is not under user control. Together these two schemes make a 64-bit (40 + 24) encryption scheme. Some vendors refer to this level of WEP as 40-bit and others refer to this as 64-bit. ASUS WLAN products use the term 64-bit when referring to this lower level of encryption. 128-bit WEP Encryption 104-bit WEP and 128-bit WEP are the same encryption method and can interoperate on a wireless network. This level of WEP encryption uses a 104-bit (26 Hex character) encryption scheme as a secret key which is set by the user, and a 24-bit "Initialization Vector", which is not under user control. Together these two schemes make a 128-bit (104 + 24) encryption scheme. Some vendors refer to this level of WEP as 104-bit and others refer to this as 128-bit. ASUS WLAN products use the term 128-bit when referring to this higher level of encryption. 4-16 Chapter 4: Configuration

Chapter 4: Configuration
WPA Encryption
When “WPA-PSK” authentication method is used, the newly proposed TKIP
(Temporal Key Integrity Protocol) or AES encryption schemes are applied.
WPA Pre-Shared Key
Select “TKIP” or “AES” in the WPA Encryption, this field is used as a password to
begin the encryption process. 8 to 63 characters are required.
WEP Encryption
When “Open or Shared Key”, “Shared Key” or “Radius with 802.1x” authentication
methods are selected, traditional WEP encrption is applied.
When “WPA” or “WPA-PSK” authentication methods are selected, you still
can set WEP encryption for those clients that do not support WPA/WPA-PSK.
Please note that Key Index for WEP key is limited to 2 or 3 when both WPA and
WEP encryption are supported at the same time.
±4/128-bit versus 40/104-bit
The following section explains low-level (64-bit) and high-level (128-bit) WEP
Encryption schemes:
±4-bit WEP Encryption
64-bit WEP and 40-bit WEP are the same encryption methods and can
interoperate in a wireless network. This level of WEP encryption uses a 40-bit (10
Hex character) encryption scheme as a secret key, which is set by the user, and a
24-bit “Initialization Vector” scheme, which is not under user control.
Together these two schemes make a 64-bit (40 + 24) encryption scheme. Some
vendors refer to this level of WEP as 40-bit and others refer to this as 64-bit. ASUS
WLAN products use the term 64-bit when referring to this lower level of encryption.
128-bit WEP Encryption
104-bit WEP and 128-bit WEP are the same encryption method and can
interoperate on a wireless network. This level of WEP encryption uses a 104-bit
(26 Hex character) encryption scheme as a secret key which is set by the user,
and a 24-bit “Initialization Vector”, which is not under user control.
Together these two schemes make a 128-bit (104 + 24) encryption scheme. Some
vendors refer to this level of WEP as 104-bit and others refer to this as 128-bit.
ASUS WLAN products use the term 128-bit when referring to this higher level of
encryption.
