Chapter 4: Configuration
WEP
WEP Authentication: There are three options to choose, Open System, Shared Key and Both.
The default is set to Open System which does not request a shared key between the AP sender
and the AP client, only supplying a correct SSID and an encryption key if there is any. With Share
Key authentication, the AP client is granted only if it provided correct challenge response to the AP.
WEP Encryption: To prevent unauthorized wireless stations from accessing data transmitted over
the network, the router offers highly secure data encryption, known as WEP. If you require high
security for transmissions, there are two alternatives to select from: WEP 64 and WEP 128. WEP
128 will offer increased security over WEP 64.
Passphrase: This is used to generate WEP keys automatically based upon the input string and a
pre-defined algorithm in WEP64 or WEP128. You can input the same string in both the AP and
Client card settings to generate the same WEP keys. Please note that you do not have to enter
Key (0-3) as below when the Passphrase is enabled.
Default Used WEP Key: Select the encryption key ID; please refer to Key (0-3) below.
Key (0-3): Enter the key to encrypt wireless data. To allow encrypted data transmission, the WEP
Encryption Key values on all wireless stations must be the same as the router. There are four keys
for your selection. The input format is in HEX style, 5 and 13 HEX codes are required for WEP64
and WEP128 respectively, the separator is “-“. For example, using WEP64, 11-22-33-44-55 is a
valid key, whilst 1122334455 is invalid.
