Wireless Configuration

v1.0, May 2008

–

WEP — 

Wired Equivalent Privacy (WEP) data encryption provides moderate data 

security. WEP Shared Key authentication and WEP data encryption, while weaker than 
newer security protocols, will block all but the most determined eavesdropper. 

–

WPA — 

Wi-Fi Protected Access (WPA) uses either TKIP data encryption or the newer 

AES data encryption to provide much better data security than WEP. Combining strong 
authentication with dynamic per-frame rekeying, WPA is virtually impossible to 
compromise. Older wireless devices may not support WPA, or may only support WPA 
with TKIP encryption. Windows XP and Windows 2000 with Service Pack 3 or above 
include the client software that supports WPA, but your wireless adapter hardware must 
also support WPA. Consult the product document for your wireless adapter and WPA 
client software for instructions on configuring WPA settings

–

WPA2 — 

WPA2 is a later version of WPA with additional security enhancements. WPA2 

supports only AES encryption. Windows XP and Windows 2000 with Service Pack 3 do 
not include the client software that supports WPA2. Make sure your wireless adapter 
hardware and driver support WPA2.

With each of these data encryption methods, you have the choice of using one of these 
authentication methods:

–

PSK — 

With pre-shared key (PSK), all wireless devices on your network must know a 

special passphrase in order to join the network. Because all users share the same 
passphrase, this method is only recommended for small networks or home networks.

–

RADIUS

 — A large network will typically contain a Remote Authentication Dial In User 

Service (RADIUS) server that stores and verifies account information for many users. A 
network access device such as the DGFV338 can request a user name and password from 
each new device that tries to join the network. The network access device then forwards 
this information to the RADIUS server for verification before granting network access to 
the new device.

Your wireless security settings can affect the time it takes to establish a wireless connection, your 
connection speed, and the power consumption of your mobile computers. WEP connections, for 
example, can take slightly longer to establish and can consume more battery power on a notebook 
computer. Failure to configure wireless security, however, exposes your network data to intruders.
