throughout a building without being bound by a LAN wire. This is accomplished through the use of a device known as the Access Point (AP). By
making use of AP in the office, you can easily establish mobile network
connections to the enterprise Intranet or Internet. Moreover, you can bring
your ASUS USB SpaceLink Client home to make your home-networking
dream come true! A home-dedicated AP, with built-in Internet gateway

3.4.5 Config - Encryption Tab
Lets you configure the ASUS USB SpaceLink Client encryption settings.
For data confidentiality in a wireless environment, IEEE 802.11 specifies a
Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy
similar to wired network. The WEP uses keys to encrypt transmitted data
packets and decrypt received data packets. The encryption process can
scramble frame bits to avoid disclosure to others.
Chapter 3
Data encryption (WEP enabled)
This option allows you to enable or disable the Wired Equivalent Privacy
(WEP) function. If this check box is selected, a WEP Key is used to encrypt your data before it is transmitted over the air.
If you enable WEP encryption, you will only be able to communicate with
wireless devices that use the same WEP keys.
WEP Key
This option is enable only if you enable WEP Encryption. The WEP Key is
a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to
encrypt transmit data packets and decrypt received data packets.
32
ASUS USB SpaceLink Client
Chapter 3 - Reference
Key Format
You can enter the WEP Key as Hexadecimal digits (0~9, a~f, and A~F), or
as ASCII characters, based on the state of the Key Format.
Key Length
For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII
characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or 13 ASCII characters.
Chapter 3
Two ways to assign WEP keys
Manual Assignment – When you click this button, the cursor appears in
the field for Key 1. For 64-bit encryption, you are required to enter four
WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~F).
For 128-bit encryption, you are required to enter four WEP Keys. Each
Key contains exactly 26 hex digits (0~9, a~f, and A~F).
Automatic Generation – Type a combination of up to 64 letters, numbers,
or symbols in the Passphrase column, then the Wireless Settings Utility
uses an algorithm to generate four WEP Keys for encryption.
NOTE: This function eases users from having to remember their
passwords and is compatible to some existing WLAN utilities, but
this is not very secure. “Manual Assignment” is more secure.
Default Key – The Default Key field lets you specify which of the four
encryption keys you wish to use to transmit data on your wireless LAN.
You can change the default key by clicking on the down arrow at the right
of this field, selecting the number of the key you want to use, and then
clicking the Apply button. As long as the Access Point or station with which
you are communicating has the same key in the same position, you can use
any of the keys as the default.
Click the Apply button to create your encryption keys. After you click the
Apply button, the “Wireless Settings” utility uses asterisks to mask your
keys.

64/128bits versus 40/104bits
You may be confused about configuring WEP encryption, especially when
using multiple wireless LAN products from different vendors. There are
two levels of WEP Encryption: 64 bits and 128 bits.
First, 64 bit WEP and 40 bit WEP are the same encryption method and can
interoperate in the wireless network. This lower level of WEP encryption
uses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 64
bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and
others refer to this as 64 bits. ASUS SpaceLink products use the term 64
bits when referring to this lower level of encryption.
Chapter 3
Second, 104 bit WEP and 128 bit WEP are the same encryption method
and can interoperate in the wireless network. This higher level of WEP
encryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),
and a 24 bit “Initialization Vector” (not under user control). This together
makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104
bits and others refer to this as 128 bits. ASUS SpaceLink products use the
term 128 bits when referring to this higher level of encryption.

3.4.6 Config - Advanced Tab
Chapter 3
Advanced tab provides some additional settings for the ASUS USB
SpaceLink Client. The “Advanced” tab is hidden until you click Advanced
on the Config - Basic page.
NOTE: This page is for advanced users. Do not change these settings if you do not fully understand these items.
RTS Threshold
Defines the size of packets that the station uses for RTS/CTS handshake
boundary. Setting the minimum size packet too small causes RTS packets
to be sent more often, adding excessive overhead to the network and decreasing network utilization. However, the more often RTS packets are
sent, the more transmission collisions can be avoided. RTS threshold ranges
from 0 to 2346 in 64 steps.
Fragmentation Threshold
Define the number of bytes used for fragmentation boundary. If the length
of the data unit exceedsthis parameter , it will be divided into smaller fragments for transmission. Each of the fragments is sent independently. If
there is a significant interference present, set the fragment size smaller.
Otherwise, set the fragment size larger. Because send multiple frames lead
to overhead on the network.Fragmentation Threshold ranged from 256 to
2432 steps 128.
ASUS USB SpaceLink Client

Chapter 3 - Reference
Authentication Algorithm
Because there is no precise bound in wireless LANs, it needs to be implemented in another mechanism to provide a higher level of security. That is
where Authentication services come in. If a mutual authentication relationship has not been established between the ASUS USB SpaceLink Client(s)
and the Access Point(s), an association cannot be established.
Auto based on WEP setting – Switch the authentication mode based upon
the ASUS USB SpaceLink Client using WEP encryption or not.
Open System – A null authentication algorithm. A station can authenticate
with any other station or Access Point and without checking any WEP Key,
even if one exists.
Chapter 3
Share Key – In a Share Key Authentication system, four-step exchange of
frames is required to validate that the station is using the same WEP Key as
the Access Point. Using this Authentication mechanism requires implementation of the WEP option.
Maximum Listen Interval
This value is used to indicate how often a station will wake up to listen to
beacon management frames. Listen intervals range from 0 to 77 in steps of 1.
Preamble Mode
This parameter is used to control whether frames will transmit with the
long or short preamble.

Chapter 4 - Troubleshooting
Cannot connect to a Station (ASUS USB SpaceLink Client)
Follow the procedure below to configure your ASUS USB SpaceLink Client.
a. Verify that the “Network Type” is in “Ad Hoc” mode.
b. Verify that the “SSID” of your ASUS USB SpaceLink Client is set to
“any” or set to the same “SSID” of the other station (or another ASUS
USB SpaceLink Client).
c. Verify that the “channel” of the ASUS USB SpaceLink Client is “Auto”
or set to the same “channel” of the other station (or another ASUS USB
SpaceLink Client).
d. Verify that the “Encryption” type is the same as the other station (or
another ASUS USB SpaceLink Client). If “WEP” encryption is enabled, you must set the same “WEP” Keys on both stations.
Bad link quality or bad signal strength
There are two possible reasons. First is radio interference, keep the environment around the ASUS USB SpaceLink Client away from microwave
ovens and large metal objects. Then try to reorient the ASUS USB SpaceLink
Client antenna. Second is the distance, decrease the distance between your
ASUS USB SpaceLink Client and the Access Point or station (or another
ASUS USB SpaceLink Client).
Chapter 4
The TCP/IP protocol did not bind to the SpaceLink PC Card.
This will occur when the computer already has six TCP/IP bindings in
Windows 98 or ten bindings in Windows Me. These limits are imposed by
the Microsoft operating system.
Solution: If your computer already has the maximum number of TCP/IP
bindings, remove one of the network adapters from the Network configuration before installing the ASUS USB SpaceLink Client driver.
In Ad Hoc network mode, I have connected to a station but my
ASUS USB SpaceLink Client cannot get an IP address.
Windows Me/2K/XP contains the “Media Sensing” feature, which can detect a disconnect state on the media, it removes the bound protocols from
that adapter until it has detected a link. But in Ad Hoc mode, it will erroneously detect the media as being disconnected.
Solution: (1) Run Wireless Settings (2) click Config (3) uncheck Detect
connection to network media (4) click Apply (5) restart your computer
