Introduction
The D-Link Air DWL-122 Wireless USB Adapter is a convenient Plug & Play USB
1.1 solution that brings wireless networking to your laptop or desktop PC.
With transfer rates up to 11Mbps* you can connect to a wireless network at
home, at the office or at any wireless hotspot. Now you can stay connected
wherever you are and wherever you go.
The DWL-122 is Wi-Fi compliant, meaning that it can connect and interoperate
with other 802.11b Wi-Fi-compliant wireless routers, access points and adapters.
The DWL-122 connects to any available USB port on a laptop or desktop
Windows and Macintosh-based computer and also includes a standard USB
extension cable. With the optional USB extension cable, the DWL-122 can be
positioned virtually anywhere at a workstation to achieve the best available
wireless signal reception - whether that workstation is in your office, on your
deck or patio, by the pool, at the local coffee shop, or in an airport terminal while
waiting to board your next flight.
The adapter works with Apple Mac OS X (10.2x or later) Jaguar, Microsoft
Windows XP, Windows 2000 and other Windows operating systems to
ensure that you’ll be up and running on a wireless network in just a matter of
seconds.
Using its default settings, the DWL-122 automatically connects to other D-Link
wireless products as soon as it’s active.
In addition to featuring 64- or 128-bit WEP encryption, the DWL-122 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.

WPA will be available soon as a download for Mac users.

Not all servers can provide Authentication.
