ARDWARE INSTALLATION

1. Select the Site – Choose a location for your SMC2655W Wireless

Access Point. Usually, the best location is at the center of your wireless
coverage area, if possible within line-of-sight of all wireless devices.

2. Place the Access Point in a position that gives it maximum coverage.

Normally, the higher you place the antenna, the better the
performance.

3. Position the antennas in the desired positions. For more effective

coverage, position one antenna along the vertical axis and the other
antenna along the horizontal axis (the antennas emit signals along the
toroidal plane - and thus provide more effective coverage when
positioned along alternate axis).

4. Connect the Ethernet cable – The SMC2655W can be wired to an

Ethernet network through an Ethernet device such as a hub or a
switch using category 3, 4, or 5 UTP Ethernet cable and an RJ-45
connector.

5. Connect the power cable – Connect the power adapter cable to the

9 VDC power socket on the rear panel.

Warning: Use only the power adapter supplied with the SMC2655W.

Ad Hoc Wireless LAN

An ad hoc wireless LAN consists of a group of computers, each equipped
with a wireless adapter, connected via radio signals as an independent
wireless LAN. Computers in a specific ad hoc
wireless LAN must be
configured to the same radio
channel.

An ad hoc wireless LAN can be
used for a small branch office or
SOHO operation.

ETWORK CONFIGURATION AND PLANNING

Infrastructure Wireless LAN

An integrated wired and wireless LAN is called an Infrastructure
configuration. A Basic Service Set (BSS) consists of a group of wireless PC
users, and an access point that is directly connected to the wired LAN.
Each wireless PC in this BSS can talk to any computer in its wireless group
via a radio link, or access other computers or network resources in the
wired LAN infrastructure via the access point.

The infrastructure configuration permits wireless clients to access the
wired LAN and also increases the effective wireless transmission range for
wireless clients as their signal can be passed through multiple access points.

A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure.

ETWORK TOPOLOGIES

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) is the communications domain for each
Wireless Access Point. For wireless PCs that do not need to support
roaming, set the domain identifier (SSID) of the wireless card to the BSS
ID of the Access Point to which you want to connect. Check with your
administrator for the BSS ID of the Access Point to which he wants you to
connect.

A wireless infrastructure can also support roaming for mobile workers.
More than one Access Point can be configured to create an Extended
Service Set (ESS). By placing the Access Points so that a continuous
coverage area is created, wireless users within this ESS can roam freely. All
SMC wireless network cards, adapters, and SMC2655W Wireless Access
Points within a specific ESS must be configured with the same SSID.

ROUBLESHOOTING

Check the following items before you contact SMC Technical Support.

1. If mobile users do not have roaming access to the SMC2655W access

point:

Make sure that all the SMC2655Ws and stations in the ESS in which
the WLAN mobile users can roam are configured to the same WEP
setting, SSID, and authentication algorithm.

2. If the management utility cannot connect to the SMC2655W:

Check that your local IP address settings conform to the SMC2655W
settings.

3. If you forgot your password or your SMC2655W has locked up, you

can reset it to factory defaults by performing the following steps:

• Start the utility program.

• On the main menu, click “Command.” Click “Reload Default.”

or

22

• Power off the SMC2655W.

• Use a pin to push in the reset button located on the bottom of the

SMC2655W (marked “Reload.” )

• While holding in the button, apply power to the AP.

• The AP will begin to load the default settings.

• Wait for about 5 seconds. Release the button.

• The AP will restart with the factory default settings.

ERMINOLOGY

The following is a list of terminology that is used in this document.

Access Point – An internetworking device that seamlessly connects wired
and wireless networks.

Ad Hoc – An ad hoc wireless LAN is a group of computers each with
LAN adapters, connected as an independent wireless LAN.

Backbone – The core infrastructure of a network. The portion of the
network that transports information from one central location to another
central location where it is unloaded onto a local system.

Base Station – In mobile telecommunications, a base station is the central
radio transmitter/receiver that maintains communications with the mobile
radio telephone sets within its range. In cellular and personal
communications applications, each cell or micro-cell has its own base
station; each base station in turn is interconnected with other cells’ bases.

BSS – BSS stands for “Basic Service Set.” It is an Access Point and all the
LAN PCs that are associated with it.

CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance.

ESS – ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than

one BSS is configured to become an Extended Service Set. LAN mobile
users can roam between different BSSs in an ESS (ESS-ID, SSID).

Ethernet – A popular local area data communications network, which
accepts transmission from computers and terminals. Ethernet operates on
a 10 Mbps baseband transmission rate, using a shielded coaxial cable or
shielded twisted pair telephone wire.

27

T

ERMINOLOGY

Infrastructure – An integrated wireless and wired LAN is called an
Infrastructure configuration.

Roaming – A wireless LAN mobile user moves around an ESS and
maintains a continuous connection to the Infrastructure network.

RTS Threshold – Transmitters contending for the medium may not be
aware of each other. RTS/CTS mechanism can solve this “Hidden Node
Problem.” If the packet size is smaller than the preset RTS Threshold size,
the RTS/CTS mechanism will NOT be enabled.

WEP – “Wired Equivalent Privacy” is based on the use of 64-bit or
128-bit keys and the popular RC4 encryption algorithm. Wireless devices
without a valid WEP key will be excluded from network traffic.
