Introduction

SMC’s EZ Connect Wireless Access Point/Bridge (SMC2682W) is an
11 Mbps wireless bridge that allows two or more remote Ethernet LANs
to be merged into a single virtual LAN. Workstations on each of the
remote LANs may communicate with each other as though they were on
the same physical LAN.

The Wireless Access Point/Bridge can also function as an access point and
provide transparent, wireless data communications between the wired
LAN (and/or within the wireless network) and fixed, portable, or mobile
devices equipped with a wireless adapter employing the same radio
modulation.

SNMP Settings

Use this screen to display and modify parameters for the Simple Network
Management Protocol (SNMP). The device includes an onboard SNMP
agent which monitors the status of its hardware, as well as the traffic
passing through its ports. A computer attached to the network, called a
Network Management Station (NMS), can be used to access this
information. Access rights to the onboard agent are controlled by
community strings. To communicate with the AP/Bridge, the SNMP agent
must first be enabled, and the NMS must submit a valid community string
for authentication. The options for configuring SNMP are described
below.

Ad hoc Wireless LAN (no AP or Bridge)

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.

Infrastructure Wireless LAN

The SMC2682W can also provide access to a wired LAN for wireless
workstations. An integrated wired/wireless LAN is called an Infrastructure
configuration. A Basic Service Set (BSS) consists of a group of wireless
PC’s 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 not only extends the accessibility of
wireless PCs to the wired LAN, but also increases the effective wireless
transmission range for wireless PCs by passing their signal through one or
more access points.

ETWORK CONFIGURATION AND PLANNING

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) is the communications domain for each
Wireless AP/Bridge. For wireless PCs that do not need to support
roaming, set the domain identifier (SSID) for the wireless card to the BSS
ID of the AP/Bridge to which you want to connect. Check with your
administrator for the BSS ID of the access point or bridge 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 adapters and SMC2682W Wireless AP/Bridges
within a specific ESS must be configured with the same SSID.

Infrastructure for Bridging between LANs

SMC’s EZ Connect Wireless Access Point/Bridge can serve as a
high-speed wireless bridge that allows two or more remote Ethernet LANs
to be merged into a single virtual LAN. To connect the separated wired
LANs, there are two settings for the Wireless Bridge: “Bridge Master” and
“Bridge Slave.” (see page 14.)

Bridges serving as local units are connected to the primary backbone
infrastructure and are set to “Bridge Master.” Those acting as remote
Bridges, attached to a remote backbone and communicating via radio to
the local unit, are set to “Bridge Slave.”

Point-to-Point Wireless Bridge

The Point-to-Point Wireless configuration uses two Wireless Bridge units

N

ETWORK TOPOLOGIES

to connect two individual LANs.

27

Point-to-Multipoint Wireless Bridge

When connecting three or more LANs the local bridge needs to be
configured as a “Bridge Master” and each remote unit configured as a
“Bridge Slave.”

Wireless Bridge with Wireless End Nodes

A Wireless AP/Bridge, when functioning as a Bridge Master, has the
capability to serve the wireless client nodes within its range. The wireless
client device can establish radio contact with the Wireless Bridge Master
and have wireless access to all local and remote LANs, workstations, and
network resources.

ROUBLESHOOTING

Check the following items before you contact SMC Technical Support.

1. If mobile users do not have roaming access to the SMC2682W
Wireless AP/Bridge, check the following:

Make sure that all the SMC2682Ws and wireless devices 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 SMC2682W cannot be configured using the Web browser:

• Remove power from the SMC2682W.

• Push in the reset button located on the back of the SMC2682W.

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

• Wait until both the wireless Activity LED, and the wireless Link
LED both start to flash on and off together (about 5 seconds).

• Release the reset button and the LEDs will turn off. You are now
in the Control Mode.

29

T

ROUBLESHOOTING

• Select the desired function by pressing the reset button. Hold the
button until the LEDs change to the next configuration.

Link LED Activity LED Action

OFF OFF No Action; will boot normally

OFF ON Revert to Factory Default settings.

ON OFF Force boot from Primary code image.

ON ON No Action; will boot normally

(The function changes to the next in sequence every time the
reset button is pressed.)

Control Mode will automatically terminate if the AP/Bridge does
not detect the reset button has been pressed for approximately 3
seconds. At that point it will flash both LEDs twice, indicating it
is proceeding with the boot.

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
radiotelephone 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).

35

T

ERMINOLOGY

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 shielded coaxial cable or
shielded twisted-pair telephone cable.

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. The 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.
