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.

Tx Rate - Indicates the communication rates. Select  
appropriate transmission speed to match your wireless  
LAN settings ("Fully Automatic" is the default setting).  
I
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).  
I
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.

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:  
I
Make sure your BIOS correctly supports the PCI Local  
Bus Specification v2.0 or later and upgrade your  
computer BIOS to the latest version.  
I
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 computers manual and check the PCI BIOS  
Setup program to be sure the PCI slot is an enabled  
bus-master slot.  
I
I
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 computers manual and check the PCI BIOS Setup  
program configuration options for ISA cards.  
 
             
24  
CHAPTER 5: TROUBLESHOOTING  
I
I
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.  
I
If it still does not work, remove the wireless adapter.  
Delete the appropriate system file (see list below) from  
c:\windows\system:  
I
I
I
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:  
I
Make sure the correct software driver is installed for  
your operating system. If necessary, try reinstalling the  
driver.  
I
I
I
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.  
I
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:  
I
I
I
I
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.
