NETWORK CONFIGURATION AND
PLANNING
WN3501AR Wireless Solution supports a stand-alone
wireless network configuration, as well as an integrated
configuration with 10 Mbps Ethernet LANs.
The WN3501AR USB adapter can be configured as:
Ad hoc for departmental or SOHO LANs
Infrastructure for enterprise LANs
Network Topologies
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 therefore be configured to the same radio
channel.
An ad hoc wireless LAN can be used for a branch
office or SOHO operation.
23
![](/img.php?id=172618&img=bg1b.png)
Infrastructure Wireless LAN
The WN3501AR 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 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.
24
![](/img.php?id=172618&img=bg1c.png)
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 BSS ID of the
access point you want to connect to. Check with your
administrator for the BSS ID of the access point he
wants you to connect to.
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 Wireless
Access Points within a specific ESS must be
configured with the same SS ID.
Before setting up an ESS for roaming, you need to
choose a clear radio channel and ideal location for the
Access Points to maximize performance. (Refer to
Using the Wireless LAN Utility on page 15 for
detailed information on installation and usage.)
25
TROUBLESHOOTING

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 which the station
associated with is powered on.
Check to make sure your wireless settings (i.e.
WEP, SSID, Channel) match the AP or other
stations you are connecting to.
If you still cant connect, change the Access Point
and all the stations within the BSS to another
radio channel.

TERMINOLOGY
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 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 PCs that are associated with it.
Data Frame The packets transmit/receive from the device.
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 transmission from computers
and terminals. Ethernet operates on a 10 Mbps base
band transmission rate, using a shielded coaxial cable
or over twisted pair telephone wire.
31
Fragmentation Threshold In the 802.11 Standard, the
MAC Layer may fragment and reassamble 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 configuration.
Management Frame Control frame for establishing the
link between Access Point and client station. It should
include the Beacon, Probe, Authentication, and
Association frame.
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 keys and the popular RC4 encryption algorithm.
Wireless devices without a valid WEP key will be
excluded from network traffic.
