1. Introduction
Chapter 1 - Introduction
10 ASUS 802.11g Access Point
1.4 Wireless Performance
This section provides the user with ideas for how to improve the performance
of a ASUS WLAN network.
1.4.1 Site Topography
For optimal performance, place wireless mobile clients and the ASUS AP s
away from transformers, heavy-duty motors, uorescent lights, microwave
ovens, refrigerators, and other industrial equipment. Signal loss can occur
when metal, concrete, walls or oors block transmission. Place the ASUS
APs in open areas or add the ASUS APs as needed to improve coverage.
Microwave ovens operate in the same frequency band as the ASUS AP. If
you use a microwave within range of the ASUS AP you may notice network
performance degradation. But, both your microwave and your the ASUS AP
will continue to function.
1.4.2 Range
Every environment is unique with different obstacles, barriers, and materials.
It is difcult to determine the exact range that will be achieved without
testing. However, has developed some guidelines to estimate the range that
users will see when the product is installed in their facility. There are no
hard and fast specications.
Radio signals may either reect on or be absorbed by obstacles depending on
their construction. For example, with two 802.11b radios, you may achieve
up to 1000 in open space outdoors where two devices have a line of sight,
meaning they see each other with no obstacles. However, the same two units
may only achieve up to 300 of range when used indoors.
By default, the ASUS AP will automatically adjust the data rate to maintain
a usable radio connection. A client that is close to the ASUS AP may operate
at higher speeds while a client that is on the fringe of coverage may operate
at lower speeds. You can congure the data rates that the ASUS AP will
use. If you limit the range of data rates available to the ASUS AP, you may
reduce the effective wireless range of the WLAN coverage.

1. Introduction
ASUS 802.11g Access Point 11
Chapter 1 - Introduction
1.4.3 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
facility. 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
congured with an ID, known as the SSID or ESSID. Wireless mobile clients
must be congured with the same SSID as the ASUS APs on the network. A
client can only roam between ASUS APs that share the same SSID.
1.4.4 Roaming Guidelines
• An ASUS WLAN Card can only roam between APs of the same type.
• All ASUS APs must have the same SSID.
• All computers with ASUS WLAN Cards must have the same SSID as
the Access Points that they will roam.
• If WEP encryption is enabled, then all ASUS APs and client adapters
must use the same encryption level and WEP Key(s) to communicate.
• The 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 facility.

2. Installation
This chapter describes the installation procedure for the ASUS 802.11g AP
and includes a description of the LEDs found on the unit.
2.1 Installation Procedure
Follow these steps to install the ASUS 802.11g WLAN AP.
1. Determine the best location for the ASUS 802.11g WLAN AP. Keep in
mind the following considerations:
• The maximum length of the Ethernet cable that connects the Access
Point to the network is 100 meters.
• For standard placement, try to place the Access Point on a at, 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 place the Access Point or its antennas so that it will
provide coverage to all of the wireless mobile devices in the area.
• Use only the power supply that came with this unit. Other power
supplies may t but the voltage and power may not be compatible.
Note: The ASUS 802.11g AP must be operated at least 20 centimeters
from any person. This is necessary to ensure that the product is oper-
ated in accordance with the RF Guidelines for Human Exposure which
have been adopted by the Federal Communications Commission.
2. Place the Access Point in the desired location. Wall mounting is also
possible for theAccess Point. Refer to the section entitled “Wall Mounting
Option” on the next page for details.
3. Attach one end of an RJ-45 Ethernet cable to the Access Point and attach
the other end to the RJ-45 10Base-T port of a network hub, switch, router,
or patch panel (possibly on a wall).

2. Hardware
Chapter 2 - Hardware Installation
ASUS 802.11g Access Point 15
4. Attach one end of the AC power adapter to the back of theASUS 802.11g
AP and the other end to a power outlet.
2.2 Wall Mounting Option
The ASUS WL-320gE Access Point is designed to sit on a raised at
surface like a le cabinet or a book shelf. The unit may also be converted
for mounting to a wall.
To mount the ASUS 802.11g WLAN AP
to a wall:
1. Look on the underside for the two
mounting hooks.
2. Mark two holes on the wall.
3. In the marked holes on the wall,
tighten two screws until only 1/4” is
showing.
4. Latch the hooks of the ASUS WL-320gE onto the screws.
Note: Readjust the screws if you cannot latch the Access Point onto
the screws or if it is too loose.
Note: Use the Access Point only with the power adapter supplied in
the product package. Using another power supply may damage the
Access Point.
The Power LED on the front of the Access Point will light up when the unit
is powered ON. The green Link LED will turn ON to indicate that the Access
Point has a physical Ethernet network connection.

3. Software Conguration
3.1 Conguring the ASUS 802.11g AP
The ASUS 802.11g AP can be congured to meet various usage scenarios.
Some of the factory default settings may suit your usage; others may need
changing. Prior to using the ASUS 802.11g AP, you must check the basic
settings to guarantee it will work in your environment.
Conguring the ASUS 802.11g AP is done through a web browser. You
need a Notebook or a PC connected to theASUS 802.11g AP (either directly
or through a hub) and running a web browser as a conguration terminal.
The connection can be wired or wireless. For the wireless connection, you
need an IEEE 802.11g/b compatible device, such as an ASUS WLAN Card,
installed in your Notebook or PC. You should also disable WEP and set the
SSID to “default” for your wireless LAN device.
If you want to congure the ASUS 802.11g AP or want to access the Internet
through the ASUS 802.11g AP, the TCP/IP settings must be correct. Normally,
the TCP/IP setting should be on the IP subnet of the ASUS 802.11g AP.
Note: Changing TCP/IP settings may require rebooting your PC.
When rebooting, the ASUS 802.11g AP should be switched ON and
in the ready state.

Advanced IP Settings
If you want to set your IP address manually, the following default settings
of the ASUS 802.11g AP should be known:
• IP address 192.168.1.1
• Subnet Mask 255.255.255.0.
If you set your computer’s IP manually, it needs to be on the same segment.
For example:
• IP address 192.168.1.xxx (xxx can be any number between 2 and 254 that is
not used by another device)
• Subnet Mask 255.255.255.0 (same as the ASUS 802.11g AP)
• Gateway 192.168.1.1 (this is the ASUS 802.11g AP IP address)
• DNS 192.168.1.1 (ASUS 802.11g AP IP address or your own).
