To configure security features for the Wireless interface, please open Security item from Wireless

WPA-PSK. Different item leads different web page settings. Please read the following information
carefully.
For None WPA
WiFi-Protected Access: The None item
offers you the less protection for wireless
communication.
Authentication Type:
The ADSL Router supports two
authentication types: Open System and
Shared key. This should be considered with
the WEP (Wired Equivalent Privacy)
mechanism.
Open System means that it allows any
client to authenticate and attempt to
communicate with a bridge. The client
can only communicate if its WEP keys
match the router’s WEP keys.
Shared Key means that a bridge or
router will send an unencrypted text
string to any client attempting to
communicate with the router. The client
requesting authentication encrypts the
text and sends back to the router. Both
unencrypted and encrypted can be
monitored, yet it leaves the bridge
open to attack from any intruder if he
calculates the WEP key by comparing
the text strings That is why shared key
authentication can be less secure than
open authentication.
Data encryption (WEP):
Select the WEP mode for the WEP key
function. You can choose 64-bit or 128-bit
for your necessity. If you choose Off, the
Encryption Keys will not be shown on this
page. If selected, data is encrypted using the
key before being transmitted. For example, if
