WPA encryption
In addition to WEP, you can also use WPA encryption with the Bewan Wi-Fi USB 54.
Caution:
the WPA protocol can only be configured in Infrastructure mode (with an Access Point).
To configure WPA using the utility programme provided, you must first update your version of
Windows XP.
If you have already installed Windows XP Service Pack 2, the Windows XP patch for WPA is
included in the update.
If not, you will have to download and install the patch, which is available free of charge from the
official Microsoft website. Here is a link to the Windows XP (KB826942) patch download page:

WPA (
Wi-Fi Protected Access
) is a security protocol designed to replace the current WEP (Wired
Equivalent Privacy) for Wi-Fi links using static keys, which must be changed manually.
WPA uses different data encryption protocols (or algorithms):
•
TKIP (
Temporal Key Integrity Protocol
): instead of using a set key to encode the data packets, it
regularly generates new dynamic keys derived from the main key, providing increased security.
Note: all existing devices can benefit by simply upgrading the software used.
•
AES (
Advanced Encryption Standard
): this is a symmetrical algorithm for block encoding. It
operates using 128 bit blocks. This block encryption provides a greater level of security.
Caution: this requires the use of a dedicated chip. It is therefore not possible to upgrade existing
equipment. Its compatibility remains limited to devices fitted with this chip.
Proceed as follows:
1.
In the
Authentication Mode
section, select
WPA-PSK
.
2.
In the
Encryption
section, select
TKIP
or
AES
.
3.
