Setting WPA PassPhrase Encryption
WPA is a new standard-based wireless security solution developed by the Wi-Fi Alliance. WPA
also supports the WEP (Wired Equivalent Privacy) security standard. Microsoft provides a
security patch called “Windows XP Support Patch for Wireless Protected Access” on its website
for free download and it works only with Windows XP. The WPA encryption is supported on
Windows
R
XP Professional and Windows XP Home Edition.
There are two types of WPA security:
l WPA-PSK (with no server) – it uses the so-called “pre-shared key” as the security key. A
pre-shared key is basically a password that is between eight and 63 characters long. It can be
any combination of letters, numbers, and other characters. This is the typical mode that is
used in a home environment.
l WPA (with server) – it is a system where a RADIUS server distributes the keys to the clients
automatically. It is typically used in a business environment.
To enable WPA with a passphrase (WPA-PSK), select Pre-Shared Keys from the Security
Options list and place a check mark in the WPA box.
