1.4 Wireless Performance
This section provides you with information on how to improve the performance of
an ASUS WLAN network.
1.4.1 Site Topography
For optimal performance, locate wireless mobile clients and the ASUS APs 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. Locate 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 continue to function.
1.4.2 Range
Every environment is unique with different obstacles, barriers, or materials. Hence,
it is difcult to determine the exact range that will be achieved without testing.
Some guidelines have been developed so users can estimate the rage, but there
are no hard and fast specications.
Radio signals may reect off of some obstacles or be absorbed by others
depending on their construction. For example, with two 802.11b radios, you may
achieve up to 1000’ in open space outdoors where there are no obstacles between
the two devices. 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 a higher
speed while a client that is on the fringe of coverage may operate at a lower speed.
As mentioned earlier, 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.
1.4.3 Site Surveys
A site survey, a utility provided with the ASUS WLAN cards, analyzes the
installation environment and provides you with recommendations for the device
and its placement. The optimum placement differ depending on the ASUS AP
design and specications.

ASUS 802.11g Access Point 13
Chapter 1 - Introduction
1.4.4 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, which is also known
as the 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.
1.4.5 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 between.
• If WEP encryption is enabled, then all ASUS APs and client adapters must use
the same encryption level and WEP Key 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 length of the Ethernet cable that connects the Access Point to the network
must not exceed 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 locate 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 AP 802.11g AP should be 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.
2. Place the Access Point in the desired location. Wall mounting is also possible
for the Access Point. Refer to the section 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).
4. Attach one end of the bundled AC power adapter to the back of the ASUS
802.11g AP and the other end to a power outlet.

2. Hardware
Chapter 2 - Hardware Installation
ASUS 802.11g Access Point 17
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 bookshelf. The unit may also be converted for mounting to a wall
or ceiling.
Follow these steps to mount the ASUS
802.11g WLAN AP to a wall:
1. Look on the underside for the two
mounting hooks.
2. Mark two upper holes in a at surface.
3. 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 only the power adapter included 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. In addition, 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 meets various working scenarios with proper
congurations. You may need to change the ASUS AP’s default settings so as to
meet the requirements in your environment.
Conguring the ASUS 802.11g AP through a web browser. You need a Notebook
PC or desktop PC connected to the ASUS 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 PC.
You should also disable WEP and set the SSID to “default” for your wireless LAN
device.
To access the ASUS 802.11g AP, you must have the correct TCP/IP settings on
your wired or wireless clients. Ensure that the clients’ IP addresses are within the
same subnet as 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.

Settings up an IP address manually
If you want to manually assign an IP address to a client, we recommended that you
use the following settings:
• 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).
