Introduction - D-Link AirPlus Xtreme G DWL-G520 Manual

Introduction

The D-Link AirPlus Xtreme G DWL-G520 Wireless PCI Adapter is an 802.11b/802.11g
high-performance, wireless adapter that supports high-speed wireless networking.
Unlike most network cards, the DWL-G520 provides data transfers at up to 54 Mbps (up
to 108Mbps in Super G mode) when used with other D-Link AirPlus Xtreme G products.
The 802.11g standard is backwards compatible with 802.11b devices.
The DWL-G520 has the newest, strongest and most advanced security features available
today. When used with other 802.11 WPA (Wi-Fi Protected Access) and 802.1x compatible
products in a network with a RADIUS server, the security features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secret
key that changes automatically at regular intervals. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a
packet is a kind of message transmitted over a network.) This ensures much
greater security than the standard WEP security. (By contrast, the previous
WEP encryption implementations required the keys to be changed manually.)
802.1x: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server* verifies the identity of the
client attempting to connect to the network. Unfamiliar clients would be denied
access.
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-G520, used in conjunction with other WPA-compatible 802.11 products, will
still be much stronger than ever before. Utilizing the Pre- Shared Key mode of WPA,
the DWL-G520 will obtain a new security key every time it connects to the 802.11
network. You only need to input your encryption information once in the configuration
menu. No longer will you have to manually input a new WEP key frequently to ensure
security. With the DWL-G520, you will automatically receive a new key every time you
connect, vastly increasing the safety of your communication.
