4. “Rate (Mbps)” is the data transmission/reception rate setting. It can
be set to Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps. Usually this
should be set to Auto. In a radio frequency hostile environment, a
lower rate can provide more stable transmission quality.
5. Set the “RTS Threshold” to the same as that used by other devices in
your network (the default 2,347 means “Disabled”). See
“Terminology” on page 46 for a description of “RTS Threshold.”

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 TOPOLOGIES
Infrastructure Wireless LAN
The SMC2664W 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 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.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure.

The Basic Service Set (BSS) is the communication domain for each access

support roaming, set the domain identifier (SSID) for the wireless adapter
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.
Roaming Wireless PCs
A infrastructure network also supports roaming for mobile workers. More
than one access point may be configured with the same SSID 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 EZ Connect Wireless adapters and EZ Connect
Wireless Access Points within a specific ESS must be configured with the
same SSID.

ROUBLESHOOTING
USB Adapter Installation Problems
If your computer cannot find the EZ Connect Wireless USB Adapter or
the network driver does not install correctly, check the following items:
•Make sure the adapter is connected to the USB port. Check for any
hardware problems, such as physical damage to the adapter’s
connector.
•Try the adapter in another USB port. If this also fails, try using another
SMC2664W wireless adapter that is known to operate correctly.
•Make sure your computer is using the latest BIOS.
•If there are other network adapters in the computer, they may cause
conflicts. Disable or remove the other adapters from the computer and
test the wireless adapter separately.
•Check for a defective computer or USB port by trying the adapter in
another computer that is known to operate correctly.
•If there are still difficulties, remove the wireless adapter. Delete the file
“Vnetusbr.sys” from:
c:\windows\system (in Windows 98/Me)
c:\winnt\system32\drivers (in Windows 2000)
c:\windows\system32\drivers (in Windows XP)
Click Start/Settings/Control Panel. Delete the adapter from the network
configuration menu. Restart the PC and reinstall the adapter.
Network Connection Problems
If the LED on the USB adapter is not lit, or if you cannot access network
resources from the computer, check the following:
41
T
ROUBLESHOOTING
•Make sure the correct software driver is installed. Try reinstalling the
driver.
•Make sure the computer and other network devices are receiving
power.
•The access point you want to connect to may not be functioning
correctly. 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 you have configured your
system for TCP/IP.
If your wireless station cannot communicate with a computer on the
Ethernet LAN when configured for Infrastructure mode, check the
following:
•Make sure the access point that the station is associated with is
powered on.
•Check that the wireless settings (i.e., WEP, SSID, Channel) match the
access point or other stations to which you are attempting to connect.
•If you still cannot connect, change the access point and all the stations
within the BSS to another radio channel.

ERMINOLOGY
The following is a list of terminology 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.
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.
Data Frame – Packets transmitted/received by the device that carry data (see Management Frame on the next page.
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 transmissions from computers and terminals. Ethernet operates
on a 10 Mbps baseband transmission rate, using shielded coaxial cable or
twisted-pair cable.
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”.

T
ERMINOLOGY
Infrastructure – An integrated wireless and wired LAN is called an
Infrastructure configuration.
Management Frame – Control frame for establishing a link between an
access point and a client station. It includes Beacon, Probe,
Authentication, and Association frames.
MSDUs – MAC Service Data Units.
MMPDUs – MAC Management Protocol Data Units.
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.
USB – The Universal Serial Bus allows complete Plug and Play connection
of peripheral devices to a computer.
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 are excluded from network traffic.
