wireless network setup

chapter 15

Wireless Network

Each node (computer or device) on the WLAN uses a

Adapter

wireless network adapter into which a wireless transceiver,

 

with a small, integrated antenna, is built. Wireless network

 

adapters might be internal (inserted in a computer or device),

 

external (housed in a separate case), or built-in (such as the

 

adapter in the HP PSC).

 

Common adapters include the following:

 

•

USB adapter: An external device that connects to a USB

 

 

port on the computer (typically has a PCMCIA card

 

 

attached to one end).

 

•

Notebook adapter: A PCMCIA card that plugs directly

 

 

into one of the PCMCIA slots on your laptop or other

 

 

portable computer.

 

•

Desktop computer adapter: A dedicated ISA or PCI card,

 

 

or a PCMCIA card with a special adapter, that plugs into

 

 

your desktop computer.

 

•

AirPort adapter: A wireless card that plugs directly into

 

 

the AirPort slot on your Macintosh laptop or desktop

 

 

computer. AirPort adapters eliminate the need for cable

 

 

connections to the computer.

 

 

WPA (TKIP)

Wi-Fi Protected Access. Provides standards-based,

 

interoperable security to strongly increase the level of data

 

protection and access control for a wireless LAN. To improve

 

data encryption, WPA uses the Temporal Key Integrity

 

Protocol (TKIP). To strengthen user authentication, WPA

 

implements 802.1x and the Extensible Authentication

 

Protocol (EAP).

 

WPA supports two basic solutions: Enterprise and Home/

 

SOHO. In an enterprise environment with IT resources, Wi-Fi

 

Protected Access is used in conjunction with an

 

authentication server such as RADIUS to provide centralized

 

access control and management. In a home/SOHO

 

environment, WPA runs in a special home mode called

 

Pre-Shared Key (PSK) which uses manually-entered keys or

 

passwords to provide security. PSK is designed to be easy to

 

set up for the home or small office user.

 

 

Note: WPA/802.1x and WPA/PSK parameters can

 

 

only be entered through the EWS.

 

 

WPA/PSK

Wi-Fi Protected Access/Pre-Shared Key. In WPA/PSK

 

authentication, clients are authenticated using a shared

 

master secret key. See WPA (TKIP) above.

 

 

Note: All devices on the network must use the same

 

 

pre-shared key. The pre-shared key must be

 

 

implemented through the HP PSC embedded Web

 

 

server.
