Wireless Performance
This section provides a few ideas to help you improve the performance of your WLAN.
Site Topography
For optimal performance, locate wireless mobile clients and the
ASUS WL-HDD2.5 away from transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators, and other industrial
equipment. Signal loss can occur when metal or concrete walls or
floors block transmission. Locate the ASUS WL-HDD2.5 in open
areas or add more devices (APs) as needed to improve coverage.
Microwave ovens operate in the same frequency band as the ASUS
WL-HDD2.5. Therefore, if you use a microwave oven within range of
your device, you may notice network performance degradation. However, your microwave oven and ASUS WL-HDD2.5 will continue to
function.
Range
Every environment is unique with different obstacles, barriers, materials, and so on. Therefore, it is difficult to determine the exact range
of your WLAN without testing in the specific environment. However,
you can follow some of the guidelines described in this section to estimate the range of your network.
Radio signals may be reflected by some obstacles or absorbed by others depending on their construction. For example, with two 802.11b
radios, you may achieve clear reception over a distance of up to
1000 feet in open spaces, with the two devices being in line of sight
(meaning they have no obstacles in a straight line between them).
However, the same two units may only achieve up to 300 feet of
range when used indoors.
By default, the ASUS WL-HDD2.5 automatically adjusts the data
rate to maintain a usable signal connection. Therefore, a client that is
close to the ASUS WL-HDD2.5 may operate at higher speeds while a
client that is on the fringe of coverage may operate at lower speeds.
6
ASUS 802.11g WL-HDD2.5
You can configure the data rates used by the ASUS WL-HDD2.5 to
improve the performance. However, if you limit the range of data
rates available to the ASUS WL-HDD2.5, you may reduce the effective wireless range of the WLAN coverage.
Site Surveys
A site survey (utility provided with ASUS WLAN cards) analyzes the
installation environment and provides users with recommendations
for equipment and its placement. The optimum placement differs
depending on the ASUS AP design and specifications.
Roaming Between ASUS APs
If there are multiple ASUS APs on the network, then a wireless
mobile client may seamlessly roam from one ASUS AP to another.
Each ASUS AP creates its own wireless cell or coverage area. This is
also known as a Basic Service Set (BSS). Any wireless mobile client
can communicate with a particular ASUS AP if it is within the ASUS
AP’s coverage area.
If the cells of multiple ASUS APs overlap, then the wireless mobile
client may switch from one ASUS AP to another as it travels throughout the building. During the hand-off from one ASUS AP to another,
the wireless mobile client maintains an uninterrupted connection to
the network. This is known as “roaming.”
Multiple ASUS APs connected to a common Ethernet network form
an Extended Service Set (ESS). All members of an Extended Service
Set are configured with an ID, known as the SSID or ESSID. Wireless
mobile clients must be configured with the same SSID as the ASUS
APs on the network; a client can only roam between ASUS APs that
share the same SSID.
ASUS 802.11g WL-HDD2.5
7
Roaming Guidelines
• An ASUS WLAN card can only roam between APs of the same
type.
• All ASUS APs must have the same SSID.
• All ASUS WLAN cards must have the same SSID as the APs
that they will roam between.
• If WEP encryption is enabled, then all ASUS APs and client
adapters must use the same encryption level and WEP Key(s) to
communicate.
• ASUS APs’ cells must overlap to ensure that there are no gaps in
coverage and to ensure that the roaming client will always have a
connection available.
• ASUS APs that use the same Channel should be installed as far
away from each other as possible to reduce potential interference.
• It is strongly recommended that you perform a site survey using
the utility provided with the ASUS WLAN card to determine the
best location for each ASUS AP in the building.

Location Tips
Determine the best location for the device while keeping in mind the
following considerations:
• The length of the Ethernet cable that connects the device to the
network must not exceed 100 meters.
• For standard placement, try to place the device on a flat, sturdy
surface as far from the ground as possible, such as on top of a
desk or bookcase, keeping clear of metal obstructions and away
from direct sunlight.
• For external antenna mounting, install the external antennas so
that they are clear of obstructions; refer to the documentation that
came with the antennas for mounting and installation instructions.
• Try to centrally locate the device and its antenna so that it will
provide coverage and access to its hard disk drive to all of the
wireless mobile devices in the area.
• Use only the power supply that came with this unit. Other power
supplies may fit but the voltage and power may not be compatible.
Note: It is the responsibility of the installer and users of the
ASUS WL-HDD2.5 to guarantee that the antenna is operated at
least 20 centimeters from any person. This is necessary to
ensure that the product is operated in accordance with the RF
Guidelines for Human Exposure which have been adopted by
the Federal Communications Commission.
12
ASUS 802.11g WL-HDD2.5
Making Connections
You can use your ASUS WL-HDD2.5 as an Access Point or as a
wireless network storage device in an existing WLAN. When the
ASUS WL-HDD2.5 is turned on, it searches for other existing Access
Points in its vicinity. If no other AP is found, it acts as an AP, while at
the same time allowing access to its hard disk drive. If an existing
WLAN and AP is found in the vicinity, it acts as a wireless shared
hard disk that can be accessed by other wireless clients in the WLAN.

Interface
The Interface submenu has the following options:
Region: Scroll through this drop-down box to select the appropriate
region where you are located.
SSID: The SSID is an identification string of up to 32 ASCII characters unique to every AP. The SSID is also referred to as the “ESSID”
or “Extended Service Set ID.” By default, the SSID is set to
ASUS 802.11g WL-HDD2.5
49
“WL-HDD”. All the wireless clients in the vicinity must have the
same SSID in order to use the ASUS WL-HDD2.5. This field is also
used as the device name when you are looking for the ASUS
WL-HDD2.5 through the Windows Network Neighborhood function.
Channel: The 802.11g and 802.11b specification supports up to 14
overlapping channels for radio communication. Choose an appropriate channel for the operating radio frequencies or choose Auto to
select a channel automatically. The available channels change according to the Region selected.
Data Rate (Mbps): This field allows you to specify the transmission
rate. Select Auto to maximize performance.
54g Mode: This field indicates the 802.11g interface mode. Selecting
Auto allows both 802.11g and 802.11b clients to connect to the
ASUS WL-HDD2.5. Selecting 54g Only maximizes performance,
but prevents 802.11b clients from connecting to the device. If 54g
Protection is checked, G-Mode protection of 802.11g traffic is

ASUS 802.11g WL-HDD2.5
Encryption: If the Open System or Shared Key or Shared Key
authentication method is used, WEP (Wired Equivalent Privacy)
encryption is applied. If the WPA-PSK method is used, a newly proposed TKIP or AES encryption in WPA is applied.
Enabling WEP can protect your data from eavesdroppers. If you do
not need this feature, select None to skip the following setting. The
ASUS WL-HDD2.5 supports both 64-bit and 128-bit encryption
using the WEP algorithm. Select the type of encryption you want to
use (64 or 128 bit) and configure one to four WEP Keys. The 128-bit
method is more secure than the 64-bit method.
64/128 bits versus 40/104 bits: 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. 64-bit WEP and 40-bit WEP are the
same encryption method and can inter-operate in the wireless network. This lower level of WEP encryption uses a 40 bit (10 hex digits
[0~9, a~f, and A~F]) 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 WLAN products use the term 64
bits when referring to this lower level of encryption. Secondly, 104 bit
WEP and 128 bit WEP are the same encryption method and can
inter-operate in the wireless network. This higher level of WEP
encryption uses 104 bits (26 hex digits) 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 WLAN
products use the term 128 bits when referring to this higher level of
encryption.
Passphrase: If you select TKIP only or AES only as the Encryption
method, this field will be used as a password for the encryption process. A password with 8 to 63 characters is required. If you select
WEP-64 bits or WEP-128 bits as the Encryption method, this field
will be used to generate four WEP keys automatically. A WEP key is
either 10 or 26 hexadecimal digits based on whether you select 64 bit
ASUS 802.11g WL-HDD2.5
51
or 128 bit in the WEP pull-down menu. Type a combination of up to
64 letters, numbers, or symbols in this field, which will be used to
generate the four WEP keys. If you want to type in the keys manually,
leave this field blank. The Asus WLAN family of products uses the
same algorithm to generate the keys so that all the products can use
the same WEP key.
Note: This function saves users from having to remember their
passwords and is compatible for all ASUS WLAN products. However, this is not as secure as the manual assignment of the keys.
WEP Key: At most four WEP keys can be set. A WEP key is either
10 or 26 hexadecimal digits (0~9, a~f, and A~F) based on whether
you select 64 bit or 128 bit in the WEP pull-down menu. The ASUS
WL-HDD2.5 and ALL of its wireless clients MUST have the same
default key.
Default Key: The Default Key field lets you specify which of the
four encryption keys you use to transmit data on your wireless LAN.
As long as the ASUS WL-HDD2.5 or a wireless mobile client with
which you are communicating has the same key in the same position,
you can use any of the keys as the default key. If the ASUS
WL-HDD2.5 and ALL of its wireless clients use the same four WEP
keys, select key rotation to maximize security. Otherwise, choose
one key in common as the default key.
Hide SSID : By default, No is selected so that wireless mobile users
can see your ASUS WL-HDD2.5’s SSID and join the network. If Yes
is selected, your ASUS WL-HDD2.5 will not show in site surveys by
wireless mobile clients and they will have to manually enter your
device’s SSID. If you want to restrict access to your ASUS
WL-HDD2.5, this is a simple way to do it.
Basic Rate Set: This field indicates the basic rates that wireless clients must support. Use 1 & 2 Mbps only when backward compatibility is needed for some older wireless LAN cards with a maximum bit
rate of 2 Mbps.
52
ASUS 802.11g WL-HDD2.5
WPA Re-key Timer: This field specifies the time interval after
which the WPA group key is changed in seconds. 0 means no periodic
key-change is required.
Bridge
ASUS 802.11g WL-HDD2.5
53
The bridge or WDS (Wireless Distribution System) enables you to
connect to one or many APs through a wireless connection. Choose
an AP mode and configure the WDS settings as follows:
AP Mode: AP Mode configures the ASUS WL-HDD2.5 for a specific purpose. By default, the device is set to serve as an Access Point
(AP only) where a wireless mobile client can connect wirelessly to a
wired Ethernet network. Choose WDS only for communicating with
other APs. Hybrid allows you to use the device both as an AP as well
as a wireless bridge.
Channel: All the Access Points in a Wireless Bridge mode must be
set to the same channel. The channel is set to 1 for WDS and Hybrid
AP modes.
Connect to APs in Remote Bridge List (Yes/No): Select Yes to connect to access points in the remote bridge list.
Allow anonymous? (Yes/No): Select Yes to allow users without
accounts to connect to the AP.
Note: If Connect to APs in Remote Bridge List and Allow
Anonymous are both set to No, it means that this AP will not
connect with other APs and therefore the AP mode setting is set
automatically to AP Only.
Remote Bridge List: Use the remote bridge list to set up the MAC
addresses of the devices in the wireless bridge. Enter the MAC
address of the target APs in order to designate partners for your
device. Click Add to add the address or click Del to delete a selected
address.
