About the Product
WL230USB provides wireless connectivity to desktop and laptop computers. The device
performs the function of a radio broadcaster and receiver to communicate with a
wireless network. This gives the computer connected with WL230USB the capability to
communicate with other devices and use the Internet service available in the wireless
network.
WL230USB is capable of connecting with wireless networks that utilize the Wireless B and
Wireless G protocols. Wireless B broadcasts data at a speed of up to 11 Megabits per
second (Mbps) while Wireless G promises a speed of up to 54 Mbps. Bear in mind that
these speeds have nothing to do with the speed of your Internet connection. Nowadays,
most high-speed Internet connections provide 3 to 5 Mbps, which is lower than the
speed of the Wireless B protocol.
WL230USB is easy to setup - connect it to a USB port, install the necessary driver
software, and then connect to a wireless network. USB ports look physically the same but
there are generally two variants namely USB 1.1 and USB 2.0. Connect the device to a
USB 2.0 port because it provides twice the speed of a USB 1.1 port. In most cases
especially for desktop computers, USB 2.0 ports are placed behind the computer case.
Connecting WL230USB behind the computer case impedes signal strength because the
device is partly hidden. In situations like this, use the USB Extension to help place
WL230USB more prominently to the host access point.

Data Encryption with WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted
between the wireless LAN adapter and the AP or other wireless station to keep network
communications private.
Both the wireless stations and the access points must use the same WEP key for data
encryption and decryption.

IEEE 802.1x
The IEEE 802.1x standard outlines enhanced security methods for both the authentication
of wireless stations and encryption key management. Authentication can be done using
an external RADIUS server.
EAP Authentication
EAP (Extensible Authentication Protocol) is an authentication protocol which runs on the
top of IEEE 802.1x transport mechanism in order to support multiple types of user
authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access
point helps a wireless station and a RADIUS server perform authentication.
Page 25 of 37
User Manual
The type of authentication you use depends on the RADIUS server and an intermediary
AP that supports IEEE 802.1X. You must first have a wired connection to the network and
obtain the certificate from a certificate authority (CA). A certificate can be used to
authenticate users and a CA issues certificates and guarantees the identity of each
certificate owner.
WPA(2)
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 is a wireless
security standard that defines stronger encryption, authentication and key management
than WPA.
WPA
WPA:::: Allows you to gain access to a more secured wireless network that requires mutual
WPAWPA
authentication between client and access point with a Radius authentication server or
other authentication server on the network. WPA uses 802.1X and Extensible
Authentication Protocol (EAP) for authentication. WPA offers Enterprise and individual
needs to meet the different market segments. This product supports various EAP types
(TLS and PEAP), which require different credential authentication. In order to access the
wireless network, you must select EAP type your service provider supplied in the section
of IEEE802.11

PSK:::: WPA offers a Personal mode of operation. In the Personal mode of operation, a

pre-shared key is used for authentication. WPA-PSK allows you to gain access to a
secured wireless network that the station and the access point use the same pre-shared
key to authenticate. You must type a mixture of numbers and letters in the Pre

Encryption Mode
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message
Integrity Check (MIC) and IEEE 802.1X. WPA2 use Advanced Encryption Standard (AES) in
the Counter mode with Cipher block chaining Message authentication code Protocol
(CCMP) to offer stronger encryption than TKIP.
The encryption mechanism used for WPA(2) and WPA(2)-PSK are the same. The only
difference between them is that WPA(2)-PSK uses a simple common password, instead
of user specific credentials. The common password approach makes WPA(2)-PSK
susceptible to brute-force password-guessing attacks but it’s still an improvement over
WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is
used to generate unique temporal encryption keys.
IEEE 802.1X Authentication
WPA and WPA2 apply IEEE 802.1X and Extensible Authentication Protocol (EAP) to
authenticate wireless stations using an external RADIUS database. WPA2 reduces the
number of key exchange messages from six to four (CCMP 4 way handshake) and
shortens the time required to connect to a network. Other WPA2 authentication features
that are different from WPA include key caching and pre-authentication.

Shared key mode.
SharedShared
Open system mode is implemented for ease-of-use and when security is not an issue. It
requires NO authentication, since it allows any device to join a network without
performing any security check. The wireless station and the AP do not share a secret key.
