NETWORK
CONFIGURATIONAND
PLANNING
SMCs EZ Connect Wireless Solution supports a
standalone wireless network configuration as
well as an integrated configuration with 10Mbps
Ethernet LANs.
The SMC wireless network cards, adapters,
Access Point and Wireless Bridge can be
configured as:
Ad hoc for departmental or SOHO LANs
Infrastructure for enterprise LANs
Infrastructure for inter-building LANs
Network Topologies
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 therefore be
configured to the same radio channel.
An ad hoc wireless LAN can be used for a
branch office or SOHO operation.
Infrastructure Wireless LAN
The SMC2682W can also provide access to a
wired LAN for wireless workstations. 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 Aaccess 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 doubles the effective
wireless transmission range for wireless PCs by
passing their signal through one or more 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.
Infrastructure Wireless LAN for
Roaming Wireless PCs
The Basic Service Set (BSS) is the
communications domain for each Access Point
or 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
Access Point 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 cards and
adapters and SMC2682W Wireless Bridges
within a specific ESS must be configured with
the same SS ID.
Infrastructure for Bridging between
LANs
SMCs EZ Connect Wireless Bridge is a high
speed wireless bridge that allows the connections
of two or more remote Ethernet LANs into a
single virtual LAN. To connect the separated
wired LANs, there are two settings for the
Wireless Bridge: Bridge Master and Bridge
Slave.
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 to connect two
individual LANs.
Point-to-Multipoint Wireless Bridge
When connecting three or more LANs (usually
in different buildings), each wired LAN requires
a Wireless Bridge. 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 Bridge, when functioning as a Bridge
Master has the capability to serve the wireless
client nodes within 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.
TROUBLESHOOTING
Check the following items before you contact
SMC Technical Support.
1.If mobile users do not have roaming access
to the SMC2682W Wireless Bridge Master,
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 Wireless 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 Push Button and the LEDs
will turn off. You are now in the Control
Mode.
Select the desired function by pressing
the reset button (Note: hold the button
until the LEDs change to the next
configuration).
The function changes to the next in
sequence every time the Push Button is
pressed. The pattern repeats (Function: 0,
1,2,3,0,1,2,3,0,...) as the Push Button is
pressed repeatedly.
Control Mode is automatically exited when
the Wireless Bridge has not detected any
Push Button pressed for approx. 3 seconds.
At that point it will flash both LEDs twice,
indicating it is proceeding with the boot.
