Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security
enhancements that strongly increase the level of data protection (encryption) and access control
(authentication) for existing and future wireless LAN systems. The technical components of WPA
include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and 802.1x for
authentication.

Parameter Description
Network Authentication Open –No authentication is needed among the wireless network.

Shared – Only wireless stations using a shared key (WEP Key identified)
are allowed to connecting each other.

WPA – This mode is for users with an authentication server (Radius
Server), WPA-enabled access point, and a WPA-enabled client. Once
WPA is enabled, all clients and access points on the network must be
WPA-enabled in order to access the network.

WPA-PSK – It is a special mode designed for home and small business
users who do not have access to network authentication servers. In this
mode, known as Pre -Shared Key, the user manually enters the starting
password in their access point or gateway, as well as in each PC on the
wireless network. WPA takes over automatically from that point, keeping
unauthorized users that don't have the matching password from joining
the network, while encrypting the data traveling between authorized
devices.

TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key
every 10,000 packet s (a packet is a kind of message transmitted over a
network.) This insures much greater security than the standard WEP
security.

Note: All devices in the network should use the same encryption method
to ensure the communication.

3.3 Current Statistics

4 Troubleshooting

This chapter provides solutions to problems usually encountered during the installation and operation
of the adapter.

1. Why can’t the USB adapter work or only work in 11b mode while connect to USB 2.0 port?

If this situation oc curs, please upgrade the driver of your USB port. This problem may be the
compatibility issue with the old driver of the USB port.

2. What is the IEEE 802.11g standard?

802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for
up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream
wireless LAN technology for the home, office and public networks.

802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for
the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b.
The 802.11g standard is backwards compatible with 802.11b.

The standard specifically calls for:

A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency

band, known as the extended rate PHY (ERP). The ERP adds OFDM as a mandatory new
coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps
(optional speeds). The ERP includes the modulation schemes found in 802.11b including
CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.

B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b

devices interoperate.

3. What is the IEEE 802.11b standard?

The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the standard for the
industry. The objective is to enable wireless LAN hardware from different manufactures to
communicate.

4. What does IEEE 802.11 feature support ?

The product supports the following IEEE 802.11 functions:

l CSMA/CA plus Acknowledge Protocol
l Multi-Channel Roaming

l

Automatic Rate Selection

l RTS/CTS Feature
l Fragmentation
l Power Management

5. What is Ad-hoc?

An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter,
Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO operation.

17

6. What is Infrastructure ?

An integrated wireless and wireless and wired LAN is called an Infrastructure c onfiguration.
Infrastructure is applicable to enterprise scale for wireless access to central database, or
wireless application for mobile workers.

7. What is BSS ID?

A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSS ID.

8. What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key
algorithm, as described in the IEEE 802 .11 standard.

9. What is TKIP?

TKIP is a quick-fix method to quickly overcome the inheren t weaknesses in WEP security,
especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security
standard, and the specification might be officially released by early 2003.

10. What is AES?

AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the
highest degree of security and authenticity for digital information, wherever and however
communicated or stored, while making more efficient use of hardware and/or software than
previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES,
TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at
the hardware level.

11. Can Wireless products support printer sharing ?

Wireless products perform the same function as LAN products. Therefore, Wireless products can
work with Netware, Windows 2000, or other LAN operating systems to support printer or file
sharing.

12. Would the information be intercepted while transmitting on air?

WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence
Spread Spectrum technology, it has the inherent security feature of scrambling. On the software
side, WLAN series offer the encryption function (WEP) to enhance security and Access Control.
Users can set it up depending upon their needs.

13. What is DSSS? What is FHSS ? And what are their differences?

Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency
in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect
is to maintain a sing le logical channel. To an unintended receiver, FHSS appears to be
short-duration impulse noise. Direct-sequence spread -spectrum (DSSS) generates a redundant
bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The
longer the chip is, the greater the probability that the original data can be recovered. Even if one
or more bits in the chip are damaged during transmission, statistical techniques embedded in the
radio can recover the original data without-the need for retransmission. To an unintended

18

receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most
narrowband receivers.

14. What is Spread Spectrum ?

Spread Spectrum technology is a wideband radio frequency technique developed by the military
for use in reliable, secure, mission -critical communication systems. It is designed to trade off
bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is
consumed than in the case of narrowband transmission, but the trade off produces a signal that
is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of
the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a
spread –spectrum sign al looks like background noise. There are two main alternatives, Direct
Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
