Infrastructure Wireless LAN
The SMC2802WV.2 also provides 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 for connection between mobile workers, as shown
in the following figure.

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 Service Set Identifier (SSID) for the wireless
card to the SSID of the access point to which you want to
connect. Check with your network administrator for the SSID.
Roaming Wireless PCs
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 adapters and access
points within a specific ESS must be configured with the same
SSID and to the same radio channel.

Before setting up an ESS for roaming, you need to choose a
clear radio channel and suitable location for the access points to
maximize performance. (Refer to “Troubleshooting” on the next
page for detailed information.)

TROUBLESHOOTING
Check the following troubleshooting items before contacting SMC
Technical Support.
Adapter Installation Problems
If your computer cannot find the SMC2802WV.2 Wireless PCI
Card, or the network driver does not install correctly, check the
following:
•Make sure the adapter is securely seated in the PCI slot.
Check for any hardware problems, such as physical damage
to the card’s connector.
•Try the card in another PCI slot. If this also fails, test your
computer with another Wireless PCI Card 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
be causing conflicts. Remove other adapters from the
computer and test the wireless adapter separately.
•Check for a defective computer or PC connection by trying the
adapter in another computer that is known to operate
correctly.
•If it still does not work, take out the wireless adapter. Delete
SMC2802WV.2.SYS from C:\windows\system. Then go to
“Control Panel” and delete the adapter from your network
configuration menu. Restart your computer and reinstall the
card.
Troubleshooting
28
Network Connection Problems
If the Link LED on the SMC2802WV.2 does not light, or if you
cannot access network resources from the computer, check the
following:
•Make sure the correct software driver is installed for your
operating system. If necessary, try reinstalling the driver.
•Make sure the computer and other network devices are
receiving power.
•The access point you want to attach to may be defective. Try
using another access point.
•If you cannot access a Windows 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 in
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.
•If you still cannot connect, change the access point and all the
stations within the BSS to another radio channel.
•Make sure the SSID is the same as that used by the BSS
configured on the access point, or the same as that used by
the access points in the extended service set (ESS).

TERMINOLOGY
Access Point – A networking 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.
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 computers 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).
Ethernet – A popular local area data communications network,
which accepts transmission from computers and terminals.
Infrastructure – An integrated wireless and wired LAN is called
an Infrastructure network.
Roaming – A wireless LAN mobile user moves around an ESS
and maintains a continuous connection to the Infrastructure
network.
WEP – “Wired Equivalent Privacy” is based on the use of 64-bit
or 128-bit keys and the popular RC4 encryption algorithm.
Terminology
34
Wireless devices without a valid WEP key are excluded from
network traffic.
