The WEP (Wired Equivalent Priv acy) mechanism impleme nted in
the SMC2336W-AG Adapter is based on the RC4 encryption
algorithm. The encryption keys are provided to ensure data
confidentiality. WEP security protects your wireless LAN against
eavesdropping and unauthorized access by intruders. If WEP is
in use, all clients on the same network must use the same WEP
key settings in order to communicate with each other.

Use Passphrase – Check this bo x to auto-generate keys for
encryption. First, check this box, then enter a string of characters
into the space. Encryption keys will be generated automatically.
When Encryption is set to 128-bit, only one key will be generated.
If Encryption is set to 64-bit, 4 keys will be generated. Note that
you must use the same passphrase and Default key on all the
other clients in your network.

Note: A passphrase string can contain up to 32 alphanumeric

characters.

Key Type – Select ASCII or Hex.

Network Configuration

and Planning

SMC’s EZ-Stream Wireless Solution supports a stand-alone
wireless network configuration, as well as an integrated
configuration with 10/100 Mbps Ethernet LANs.

The SMC2336W-AG can be configured as:

• Ad hoc - for small groups that only communicate with each

other, without access points

• Infrastructure - for wireless LANs

Network Topologies

Ad Hoc Wireless LAN

An ad hoc wireless LAN
consists of a group of
computers, each equipped
with one 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

Network Configuration and Planning

Infrastructure Wireless LANs

The SMC (802.11a/11b/11g) access points can also provide
wireless workstations with access to a wired 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 not only extends the accessibility
of wireless PCs to the wired LAN, but also extends 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 f or connection betw een mobile workers , as sho wn in
the following figure.

Setting the Communication Domain

Setting the Communication Domain

Stationary Wireless PCs

The Basic Service Set (BSS) is the communication domain for
each access point. For wireless PCs that do not need to support
roaming, set the domain identifier (SSID) for the wireless card to
the SSID of the access point you want to connect to. Check with
your administrator for the SSID of the access point you should
connect to.

Roaming Wireless PCs

A wireless infrastructure can also support roaming for mobile
workers. More than on e access point can be configured to crea te
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 adapters and access points
within a specific ESS must be configured with the same SS ID
and to the same radio channel.

Network Configuration and Planning

Before setting up an ESS f or roaming, y ou need to choose a clear
radio channel and a suitable location for the access points for
optimum perf ormance. (Ref er to “Troubleshooting” on page 3 5 f or
detailed information on installation and usage)

34

Troubleshooting

Check the following troubleshooting items bef ore contacting SMC
technical support.

Adapter Installation Problems

If your notebook cannot find the SMC2336W-AG Adapter or the
driver software does not install correctly, check the following:

• Make sure the adapter is securely seated in th e CardBus slot.

When you insert the wireless adapter into the notebook’ s slot,

Troubleshooting

your notebook shou ld make a beepin g sound, if the adapter is
properly inserted. Check for any hardwa re prob lems, such as
physical damage to the card’s connector.

• Try the card in another CardBus slot. If this also f ails, test y our

notebook with another wireless adapter that is known to
operate correctly.

• Make sure your notebook is using the latest BIOS.

• If there are other network adapters in the noteb ook, the y ma y

be causing conflicts. Remove all other adapters from the
notebook and test the wireless adapter separately.

• If it still does not work, take out the wireless adapter. Go to

“Control Panel” and delete the adapter from your network
configuration menu. Restart your laptop and reinstall the card
and the driver and utility.

35

Troubleshooting

Network Connection Problems

If the Link LED on the SMC2336W-AG Adapter does not light, or
if you cannot access any network resources from the notebook,
check the following:

• Make sure the correct software driver is installed for your
operating system. If necessary, try reinstalling the driver.

• Make sure the notebook and other network devices are
receiving power.

• The access point you wa nt to connect to may be def ective. Try
using another access point.

• If you cannot access a Windows or NetWare service on the
network, check that you have enabled and configured the
service correctly. If you cannot connect to a particular server,
be sure that you have access rights and a valid ID and
password.

• If you cannot access the Internet, be sure y ou have configured
your system for TCP/IP.

If your wireless station cannot communicate with a computer in
the Ethernet LAN when configured for Infrastructure mode, check
the following:

• Make sure the acce ss point that the station is associated with
is powered on.

• If the connection still fails, chang e the access point and all the
clients within the BSS to another radio channel.

• For a station with roaming disab led, make sure the SSID is the
same as that used by the access point, or the same as that
used by the access points in the extended service set (ESS).

Terminology

Terminology

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

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

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 o wn base station; each ba se 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.

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 standard for comp uter networks. Eth ernet networks
are connected by special cables and hubs or switches, and it
operates at 10 Mbps.

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.

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

43

Terminology

Roaming – A function that allows you to move through a
particular domain without losing network connectivity.

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 NO T be
enabled.

WEP – “Wired Equivalent Privacy” is based on th e use of 64-bit or
128-bit keys and the popular RC4 encryption algorithm for
enhanced network security.
