Wireless ADSL Modem User’s Manual 49

Security:
The ADSL Bridge/Router provides a security encryption tool known as
WEP (Wired Equivalent Privacy). WEP is designed to provide security and
privacy equivalent to that found in a wired network. This is done by encrypting
the data packets sent between client and host with an encryption key. Both the
client (PC) and the host (access point/router) must have the same WEP key in
order to communicate. The available WEP settings are 64 bit and 128 bit. The
higher the bit value on the encryption, the more secure the data transmission.
Select
Enable Encryption
to activate this feature.
•
Key Length:
Choose between 64 bit (default) and 128 bit. 128 bit offers more
security, but at the cost of slower packet processing.
Key 0-3:
You are able to enter 4 encryption keys, only one of which is enabled at
any given time. All devices on the network must share the selected key in order to
communicate with the ADSL Bridge/Router AP. The key length for 64 bit is 10
hexadecimal characters and the key length for 128 bit is 26 hexadecimal
characters.
Note: If you have the WLAN Security (see next section) enabled, always choose
WEP Key ID 2. This will allow the 802.1x client and non-802.1x client to work
simultaneously in the 802.1x WLAN security Method.
•
Auth Mode:
Select Open System or Share Key to set the authentications the
Access Point recognizes.
o
Open System: This default setting allows any device, regardless of its
WEP keys, to authenticate and then attempt to associate.
o
Shared Key: This setting tells the Access Point to send a plain-test, shared
key query to any device attempting or associate with the Access Point.
This query may leave the Access Point open to a known-text attack from
intruders and is therefore not as secure as the Open System setting.
o
Both: allow both Open System and Shared Key modes

Secret AP
: enable or disable AP broadcast to show or hide AP. When AP
broadcast is disabled, your AP would not be shown on most wireless scanners
such as NetStumbler.
Click
the
“Submit”
and
“Save Setting”
buttons once confirm your setting or
configuration and reboot the device in order to activate the setting.
