Introduction - D-Link AirPlus XTREME G+ DWL-G650+ Manual

Introduction

The D-Link AirPlus Xtreme G+ DWL-G650+ Wireless Cardbus Adapter is a 802.11g
high-performance, wireless adapter that supports high-speed wireless networking at home,
at work or in public places.
Unlike most network cards, the DWL-G650+ provides data transfers at up to 8X (compared
to the standard 11 Mbps) when used with other D-Link AirPlus Xtreme G+ products. The
802.11g standard is backwards compatible with 802.11b products.This means that you
do not need to change your entire network to maintain connectivity. You may sacrifice
some of 802.11g's speed when you mix 802.11b and 802.11g devices, but you will not
lose the ability to communicate when you incorporate the 802.11g standard into your
802.11b network. You may choose to slowly change your network by gradually replacing
the 802.11b devices with 802.11g devices .
In addition to offering faster data transfer speeds when used with other 802.11g products,
the DWL-G650+ has the newest, strongest, most advanced security features available
today. When used with other 802.11g WPA (WiFi Protected Access) and 802.1x
compatible products in a network with a radius server, the security features include:
WPA*: A new security feature, Wi-Fi Protected Access authorizes and identifies
users based on a secret key that changes automatically at a regular interval.
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 insures much greater security than the standard WEP security. (By
contrast, the older WEP encryption required the keys to be changed manually.)
802.1x*: Authentication is a first line of defense against intrusion. In the
Authentication process the 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-G650+, used in conjunction with other 802.11g products, will still be much
stronger than ever before. Utilizing the Pre Shared Key mode of WPA, the DWL-G650+
will obtain a new security key every time it connects to the 802.11g 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-
G650+, you will automatically receive a new key every time you connect, vastly increasing
the safety of your communications.
