1 Introduction  
Thank you for purchasing the Hawking Technologies Hi-Gain Mini USB Wireless-G Adapter. The  
HWU54DM complies with the IEEE 802.11g standard, which supports up to 54Mbps high-speed  
wireless networking. It is also backwards compatible with IEEE 802.11b devices. The HWU54DM is a  
high quality, high performance wireless product that has been designed with Hawking’s Hi-Gain  
Technology for improved distance and throughput. Using a unique swivel-and-rotate design paired  
with a 5dB/5dB Patch antenna, the adapter ensures you’ll get the greatest signal coverage wherever  
you are. Just point the unit in the direction of the wireless signal source and you’re sure to get the  
highest signal strength. The LED Signal Strength Indicator provides you the information you need to  
make sure you’re getting the most from your wireless connection.  
For wireless security issues, this card supports 64/128-bit WEP data encryption that protects your  
wireless network from eavesdropping. It also supports the WPA (Wi-Fi Protected Access) security  
standard that combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client  
users are required to authorize before accessing to APs or AP Routers, and the data transmitted in the  
network is encrypted/decrypted by a dynamically changed secret key. This card also has built-in an  
AES engine which ensure the highest degree of security and authenticity for digital information and it is  
the most advanced solution defined by IEEE 802.11i for security in wireless networks.

Authentication vs. Security  
Parameter  
Description  
Authentication Type  
This setting has to be consistent with the wireless networks that  
the card intends to connect to. All security keys within a network  
must match to allow successful communications.  
None – 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-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  
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. The encryption methods are including TKIP and AES.  
Note that this option is only available for Windows XP.

Parameter  
Description  
Encryption Mode  
None – 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.  
WPA Pre-Shared Key  
The WPA-PSK key can be from eight to 64 characters and can be  
letters or numbers. This same key must be used on all of the  
wireless stations in the network.  
WEP Key  
The WEP keys are used to encrypt data transmitted in the  
wireless network. There are two types of key length: 64-bit and  
128-bit. Select the default encryption key from Key 1 to Key 4 by  
selected the radio button.  
(Key1 ~ Key4)  
Fill the text box by following the rules below.  
64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9”  
range) or 5-digit ASCII characters (including “a-z” and “0-9”) as  
the encryption keys. For example: “0123456aef“ or “test1”.  
128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9”  
range) or 13-digit ASCII characters (including “a-z” and “0-9”) as  
the encryption keys. For example:  
“01234567890123456789abcdef“ or “administrator”.

3.2.2 Enable WPA in Windows XP  
Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security  
enhancement that strongly increases 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.  
There are two types of WPA security: WPA-PSK (no server) and WPA (with server). WPA requires a  
Radius Server to complete authentication among wireless stations and Access Points. Typically, this  
mode is used in an enterprise environment. WPA-PSK uses a so-called pre-shared key as the security  
key. A pre-shared key is a password that every wireless station must use to access the network.  
Typically, this mode will be used in a home environment.  
To enable the WPA function in Windows XP, the following software systems are required:  
1. Windows XP Service Pack 1 with Windows XP Support Patch for Wi-Fi Protected Access program  
in addition.  
2. Configure the card using Wireless built-in utility (Wireless Zero Configuration).  
z
Note: When using the Wireless Utility there are two function selections when you open the  
execute the program. You can select to use the XP’s built-in utility with full WPA function. If  
“Use XP Wireless Zero Configuration” is selected, you can only configure the advance  
setting or check the link status and statistics from the “RaConfig” utility.

WPA – This mode is for enterprise 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.

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.

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 DSSSWhat is FHSSAnd 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.

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).  
14. What is Hi-Gain and dBi?  
Hi-Gain is Hawking Technologies high performance wireless distance extending product line. It  
encompasses a group of products and technologies used to help solve distance issues  
accompanied with WiFi products. A unit of measurement on antenna strength and power is dBi.  
The higher the dBi or gain level of an antenna the more powerful it is.  
15. What is the difference between directional and omni-directional antennas?  
Directional and omni-directional antennas determine the wireless output pattern of antennas.  
In standard installations it is normally the wireless access point that uses the omni-directional  
antenna (360 degree wireless output) while the clients (desktop or laptops) that use the  
directional antennas (concentrated narrow wireless signal) to create a stronger link directly to  
the access point.  
16. How do I get an Optimal Wireless Connection with the HWC54D?  
If pointing the antenna directly at the access point is not providing a sufficient signal connection  
then you can try bouncing the signals off walls. Wireless signals can reflect off walls or through  
windows to get to their desired location so try different positions to find the best antenna  
orientation for your network.
