Security

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

menu. This web page offers four authentication protocols for you to secure your data while

connecting to networks. There are four selections including None WPA, 802.1X,WPA, and

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

For Open System (or Shared Key), 64-bit
