NETWORK CONFIGURATION
AND PLANNING
3
Introduction
3Com's Wireless Solution supports a stand-alone wireless
network configuration, as well as an integrated
configuration with 10 Mbps Ethernet LANs.
The Wireless PCI card 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.
14
CHAPTER 3: NETWORK CONFIGURATION AND PLANNING
Infrastructure Wireless LAN
The wireless PCI card 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.
Setting the Communication Domain
15
Setting the Communication Domain
Stationary Wireless PCs
The Basic Service Set (BSS) is the communication domain
for each 3Com wireless access point (AP). For wireless
PCs that do not need to support roaming, set the domain
identifier (SSID) for the wireless card to the BSSID of the AP
you want to connect to. Ask your administrator for the
BSSID of the AP point he or she 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 AirConnect cards 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 ideal location for the access points
to maximize performance.
CONFIGURATION AND
DIAGNOSTIC UTILITY

20
CHAPTER 4: CONFIGURATION AND DIAGNOSTIC UTILITY
The user-configurable parameters are:
■
■
■
■
■
Mode - Set the station operation mode to AdHoc for
network configurations that do not have any access
points, or to Infrastructure for configurations with
access points ("Ad hoc" is the default setting).
SSID - Input an SSID number if the roaming feature is
enabled ("101" is the default setting).
Tx Rate - Indicates the communication rates. Select
appropriate transmission speed to match your wireless
LAN settings ("Fully Automatic" is the default setting).
WEP - For more secure data transmission, select
"Enabled" to use WEP security. The advanced Wired
Equivalent Privacy (WEP) is implemented in this card to
prevent unauthorized access. However, for normal use
it is recommended to retain the factory-set "Disabled"
WEP. ("Disabled" is the default setting).
Channel - If you are setting up an Ad hoc wireless LAN,
set the channel number to the same radio channel as
that used by the other wireless clients in your group.
However, if you are connecting to a network via an
access point, then use the same channel as that used by
the access point (access point default: 3).
Using the Wireless LAN Configuration Utility
21
Encryption Screen
The WEP (Wired Equivalent Privacy) implemented in
3Com's wireless PCI card is based on an RC4 encryption
algorithm and provides a 40-bit security key to ensure data
confidentiality. This WEP security protects your wireless LAN
against eavesdropping and unauthorized access by hackers
or other intruders. If the WEP is in use, the WEP key is
required for connecting to an access point or listening to
messages that pass through the air.
To use the WEP function, take the following steps:
1 Click on the Encryption tab to set up WEP
security keys.
2 Select Enabled for the WEP field.
3 Select one encrypted key (from Key 1 to Key 4) as
your default key.
4 Click the Apply button.
TROUBLESHOOTING
5
Introduction
This chapter describes troubleshooting procedures you can
perform to solve basic problems.
Preliminary Troubleshooting
Check the following items before contacting 3Com
Technical Support.
PCI Compatibility
Some PCI computers are not self-configuring and require
you to perform some or all of the following functions by
motherboard jumper changes and/or BIOS Setup program
configuration:
■
Make sure your BIOS correctly supports the PCI Local
Bus Specification v2.0 or later and upgrade your
computer BIOS to the latest version.
■
Verify that the PCI slot is an enabled bus-master slot
and not a slave PCI slot. In some computers, the PCI
slot must be configured to enable bus mastering. Refer
to your computer’s manual and check the PCI BIOS
Setup program to be sure the PCI slot is an enabled
bus-master slot.
■
In some computers, you may be required to disable
Plug-n-Play (PnP) in the BIOS Setup program if resources
are not properly assigned between installed cards.
■
Some computers may require you to reserve interrupts
and memory addresses for installed ISA cards to prevent
PCI adapters from using the same settings. Refer to
your computer’s manual and check the PCI BIOS Setup
program configuration options for ISA cards.
24
CHAPTER 5: TROUBLESHOOTING
■
■
■
Make sure the PCI slot is configured to support INTA.
Be sure that INTA for the slot is assigned to a free
interrupt (IRQ) number.
If it still does not work, remove the wireless adapter.
Delete the appropriate system file (see list below) from
c:\windows\system:
■
Windows 9x: cw10.sys
■
Windows 2000: cw10nt.sys
■
Windows Me: cw10nt.sys
Go to "Control Panel" and delete the wireless PCI card
from your network configuration menu. Restart your
computer and reinstall the card as described in Chapter 2.
Network Connection Problems
If the Link LED on the wireless PCI card does not light, or if
you cannot access 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.
Preliminary Troubleshooting
25
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 which the station associated
with is powered on.
■
Make sure your wireless station is configured with the
same operating radio channel as the access point.
■
If you still cannot connect, change the access point and
all the stations within the BSS to another radio channel.
■
Make sure the BSSID is the same as the access point for
a station with roaming disabled, or the SSID is the same
as the access point for a station with roaming enabled.

they will be limited to the duration of the applicable written warranty. This warranty gives you specific
legal rights which may vary depending on local law.
