NETWORK CONFIGURATION

AND

SMC’s EZ Connect Wireless Solution supports a stand-alone
wireless network configuration, as well as an integrated
configuration with wireless LANs.

The SMC2635W can be configured as:

• Ad hoc - for small groups that only communicate with each
other, without an Access Point

• Infrastructure - for wireless communication with an Access
Point

PLANNING

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 wireless LAN can be
used in a SOHO or temporary environment.

NETWORK TOPOLOGIES

Infrastructure Wireless LAN

An SMC access point 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 for connection between mobile workers, as shown 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 to which you want to connect. Check
with your administrator for the SSID of the access point to which
you should connect.

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 SS ID
and to the same radio channel.

any 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 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 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.

• For a station with roaming disabled, 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).
