VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
Chapter 4: Configuration 37
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. Default Used WEP Key: Select the encryption key ID;
please refer to Key (1~4) below.
Key (1-4): 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.
