Operation Mode: This may be set to Access Point,
Repeater or Ethernet Converter.
These modes are described below:
Access Point functions as a standard IEEE 802.11b access
point
Repeater repeats an access points signals to extend the
acess points coverage
Ethernet Converter provides a wireless connection to an
access point via an RJ-45 connection to devices such as
Microsoft Xbox and Ethernet ready embedded devices

The parameters that follow may be configured in any of the three
modes descibed above but the user is advised to leave them at
their default settings.
Transmission Rate: Set the data rate transmitted from
the Wireless Access Point. The lower the data rate,
the longer the transmission distance.
(Default: Fully Automatic.)
RTS Threshold: Set the RTS (Request to Send) frame length. You
may configure the access point to initiate an RTS frame. If the
packet size is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will NOT be enabled
The access point sends Request to Send (RTS) frames to a
particular receiving station to negotiate the sending of a data
frame. After receiving an RTS, the station sends a CTS (Clear to
Send) frame to acknowledge the right of the sending station to
send data frames. The access points contending for the medium
may not be aware of each other. The RTS/CTS mechanism can
solve this Hidden Node Problem. (Default: 2347)
Fragmentation Threshold: The Fragmentation Threshold can be
set between 256 and 2,346. If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.
Fragmentation of the PDUs (Package Data Unit) can increase the
reliability of transmissions because it increases the probability of
a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will enable the retransmission of smaller frames much faster.
However, it is more efficient to set the fragment size larger if very
little or no interference is present because it requires overhead to
send multiple frames. (Default: 2346)

Basic Rate: The highest rate specified is the rate the
Wireless Access Point will use when transmitting
broadcast/multicast and management frames.
(Default: 1, 2 Mbps.)
Preamble Type: The access points and client card drivers have a
radio setting for RF Preamble. Enabling it can boost your
throughput. Preamble Type offers a drop-down list with two
options: Long or Short. If you are not sure whether all the clients
and access point radios in your wireless network support the
Short RF preamble, then leave this setting on Long (default).
Transmit Power: Set the signal strength transmitted from
the access point. The longer the transmission distance,
the higher the transmission power required. (Default:

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.

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 SS ID of the access point to which you want to
connect. Check with your administrator for the SS 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 wireless network cards, adapters,
and the wireles access point within a specific ESS must be
configured with the same SSID.
Note: If Access Point 2 is replaces by an SMC2671W set to
Repeater mode then the SMC2761W will not establish its
own BSS, but will repeat data messeges between Acess
Point 1 and end users, thus extending the coverage area
of Access Point 1.

ROUBLESHOOTING
Check the following items before you contact Technical Support.
1. If mobile users do not have roaming access to the
SMC2671W:
Make sure that all the SMC2671Ws 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 SMC:
Check that your local IP address settings conform to the
SMC2671W settings.
3. If you forgot your password or your SMC2671W 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
Power off the SMC2671W.
Use a pin to push in the reset button located on the bottom
of the SMC2671W (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).
T
ERMINOLOGY
44
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.
Infrastructure An integrated wireless and wired LAN is called
an Infrastructure configuration.
Fragmentation Threshold In the 802.11 Standard, the MAC
Layer may fragment and reassemble directed MSDUs or
MMPDUs. The fragmentation and defragmentation mechanisms
allow for fragment re-transmission.
Preamble Type Some access points and client card drivers
have a radio setting for Short RF Preamble. If all the clients and
access points in your wireless network have this feature, then
enabling it can boost your throughput. However, if a radio does
not support this feature, then it will not be able to communicate
with any other radios that have this set to Short.
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.
