Network Name (SSID)
The SSID (up to 32 printable ASCII characters) is the unique
name identified in a WLAN. The ID prevents the unintentional
merging of two co-located WLANs.
You may specify a SSID for the adapter and then only the device
with the same SSID can interconnect to the adapter.
This is a computer-to-computer

(ad hoc) network; wireless access Infrastructure – This operation mode requires the presence of an
points are not used.
802.11 Access Point. All communication is done via the Access
Point or Router.
Ad Hoc – Connect to another wireless adapter in the Wireless
LAN network without through an Access Point or Router.
If this item is selected, the adapter will work in Ad Hoc mode.
Channel
This setting is only available for Ad Hoc mode. Select the number
of the radio channel used for the networking. The channel setting
should be the same with the network you are connecting to.
14
Network Authentication
This setting has to be consistent with the wireless networks that
the adapter intends to connect.
Open System – No authentication is needed among the wireless
network.
Shared Key – Only wireless stations using a shared key (WEP
Key identified) are allowed to connecting each other.
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 wireless stations in the network.
WPA-PSK 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.
WPA2-PSK – WPA2-PSK is also for home and small business.
The difference between WPA-PSK and WPA2-PSK is that
WPA2-PSK provides data encryption via the AES. In contrast,
WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
WPA 802.1X – WPA provides a scheme of mutual authentication
using either IEEE 802.1x/Extensible Authentication Protocol
(EAP) authentication or pre-shared key (PSK) technology. It
provides a high level of assurance to enterprises, small
businesses and home users that data will remain protected and
that only authorized users may access their networks. For
enterprises that have already deployed IEEE 802.1x
authentication, WPA offers the advantage of leveraging existing
authentication databases and infrastructure.
WPA2 802.1X – Like WPA, WPA2 supports IEEE 802.1x/EAP
authentication or PSK technology. It also includes a new
advanced encryption mechanism using the Advanced Encryption
Standard (AES). AES is required to the corporate user or
government users. The difference between WPA and WPA2 is that
WPA2 provides data encryption via the AES. In contrast, WPA
uses Temporal Key Integrity Protocol (TKIP).
WEP 802.1X – It’s a special mode for using IEEE 802.1x/EAP
technology for authentication and WEP keys for data encryption.
15
Parameter
Description
Data Encryption
Disabled – Disable the WEP Data Encryption.
WEP – Enable the WEP Data Encryption. When the item is
selected, you have to continue setting the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the
temporal key every 10,000 packets (a packet is a kind of message
transmitted over a network.) This insures much greater security
than the standard WEP security.
AES – AES has been developed to ensure the highest degree of
security and authenticity for digital information and it is the most
advanced solution defined by IEEE 802.11i for the security in the
wireless network.
Note: All devices in the network should use the same encryption
method to ensure the communication.
ASCII
WEP Key can be ASCII format. Alphanumeric values or signs are
allowed to be the WEP key. It is more recognizable for user.
PASSPHRASE
It is a text string with a maximum of 32 alphanumeric characters,
for example: “Test“. The WEP Key is based upon the Passphrase
determined by you. This passphrase may not work with other
vendors’ products due to possible incompatibility with other
vendors’ passphrase generators. You must use the same
passphrase or WEP key settings for all wireless computers within
the network.
Key Length
When you select the “WEP and “PASSPHRASE“ and this function
will display in the current status of the utility.
The keys are used to encrypt data transmitted in the wireless
network. Fill the text box by following the rules below.

example: “0123456aef“.
128-bit – Input 26-digit Hex values as the encryption keys. For
example: “01234567890123456789abcdef“.
Key Index (advanced)
Select one of the four keys to be the data encryption key.
Network Key
Please enter network security key here to make sure the
password is correct.
16
Parameter
Description
Confirm Network Key
Please enter network security key here again.
EAP Type
GTC – GTC is an authentication protocol which allows the
exchange of clear text authentication credentials across the
network.
TLS – TLS is the most secure of the EAP protocols but not easy to
use. It requires that digital certificates be exchanged in the
authentication phase. The server presents a certificate to the
client. After validating the server’s certificate, the client presents a
client certificate to the server for validation.
LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many
of the features of EAP protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should be selected for
use only when limited vendor choice for client, access-point, and
server products is not a concern. When you have set up LEAP
authentication, you have to enter the user name and password of
your computer.
PEAP & TTLS – PEAP and TTLS are similar and easier than TLS
in that they specify a stand-alone authentication protocol be used
within an encrypted tunnel. TTLS supports any protocol within its
tunnel, including CHAP, MSCHAP, MSCHAPv2 and PAP. PEAP
specifies that an EAP-compliant authentication protocol must be
used; this adaptor supports MD5, TLS, GTC (Generic Token Card)
and MSCHAPv2. The client certificate is optional required for the
authentication.
Tunnel
Includes MD5, GTC, TLS, MSCHAP-v2.
Username

4 Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and operation
of the adapter.
1. 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 requires backward compatibility 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.
2. 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.
3. What does IEEE 802.11 feature support?
The product supports the following IEEE 802.11 functions:
z
z
z
z
z
z
CSMA/CA plus Acknowledge Protocol
Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS Feature
Fragmentation
Power Management
4. 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.
5. What is Infrastructure?
An integrated wireless and wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database, or
wireless application for mobile workers.
26
6. 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.
7. 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.
8. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent 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.
9. 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.
10. 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.
11. 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.
12. 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 single 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
receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most
narrowband receivers.
27
13. 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 signal looks like background noise. There are two main alternatives, Direct
Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
