What is Wireless LAN?  
Wireless Local Area Network (WLAN) systems offer a great number of advantages over  
traditional wired systems. WLAN is flexible and easy to setup and manage.  
Using radio frequency (RF) technology, a WLAN transmits and receives data through the air. A  
WLAN combines data connectivity with user mobility. For example, users can roam from a  
conference room to their office without being disconnected from the network.  
Using WLAN, users can conveniently access-shared information, and network administrators  
can configure and augment networks without installing or moving network cables.  
WLAN technology provides users with many convenient and cost saving features:  
Mobility:  
WLAN provide LAN users with access to real-time  
information anywhere in their organization, providing service  
opportunities that are impossible with wired networks.  
Ease of Installation:  
Scalability:  
Installing is easy for novice and expert users alike,  
eliminating the need to install network cables in walls and  
ceilings.  
WLAN can be configured in a variety of topologies to adapt  
to specific applications and installations. Configurations are  
easily changed and range from peer-to-peer networks suitable  
for a small number of users to full infrastructure networks of  
thousands of users roaming over a broad area.

Wireless LAN Modes  
Wireless LANs can be configured in one of two ways:  
Ad-hoc Networking  
Also known as a peer-to-peer network, an ad-hoc network is one that allows all workstations  
and computers in the network to act as servers to all other users on the network.  
Users on the network can share files, print to a shared printer, and access the Internet with a  
shared modem. However, with ad-hoc networking, users can only communicate with other  
wireless LAN computers that are in the same wireless LAN workgroup, and are within range.  
Infrastructure Networking  
Infrastructure networking differs from ad-hoc networking in that it includes an access point.  
Unlike the ad-hoc structure where users on the LAN contend the shared bandwidth, on an  
infrastructure network, the access point can manage the bandwidth to maximize its utilization.  
Additionally, the access point enables users on a wireless LAN to access an existing wired  
network, allowing wireless users to take advantage of the wired networks resources, such as  
Internet, email, file transfer, and printer sharing.

Infrastructure networking has the following advantages over ad-hoc networking:  
Extended range:  
Each wireless LAN computer within the range of the  
access point can communicate with other wireless  
LAN computers within range of the access point.  
Roaming:  
The access point enables a wireless LAN computer  
to move through a building and still be connected to  
the LAN.  
Wired to wireless LAN connectivity:  
The access point bridges the gap between wireless  
LANs and their wired counterparts.  
Notes on Wireless LAN Configuration  
When configuring a wireless LAN (WLAN), be sure to note the following points:  
Optimize the performance of the WLAN by ensuring that the distance between access  
points is not too far. In most buildings, WLAN Adapters operate within a range of 10 ~ 30  
metres, depending on the thickness and structure of the walls.  
Radio waves can pass through walls and glass but not metal. If there is interference in  
transmitting through a wall, it may be that the wall has reinforcing metal in its structure.  
Install another access point to circumvent this problem or try moving your existing access  
point.  
Floors usually have metal girders and metal reinforcing struts that interfere with WLAN  
transmission. It is recommended that you use at least one access point for each level of your  
building.

Using Wireless Utility In Windows XP  
Wireless LAN Utility  
There are two ways to configure the NetComm NP5420 11G Wireless PC Card. One is using  
the NetComm NP5420 WLAN Utility; the other one is using Windows XP’s Wireless Network  
Configuration. Once your NP5420 card is installed and your operating system has drivers  
loaded you must configure a WLAN Utility to specify the correct settings to join your Wireless  
LAN. Windows XP comes with a built-in WLAN utility, you can choose to use the XP utility  
or use NetComm's utility as provided on the CD-ROM. Windows 98/ME/2000 installations  
will need to use the NetComm utility.  
Note: You must use only one of these utilities at any one time to manage the operation of  
the card if you are having trouble disabling the Windows XP WLAN utility see the  
trouble shooting section for more information. If you wish to always use the  
Windows XP WLAN utility you should move the shortcut for the NetComm utility  
from the Startup section of your Start menu to your desktop - this will prevent the  
NetComm Utility from launching when Windows is started.  
Using Windows Wireless Network Configuration  
1. Click the right key of the mouse on the Wireless LAN Utility icon and select Exit from the  
pop-up menu.  
2. Click on the Windows Wireless Network Configuration icon.  
3. The Connect to Wireless Network window will appear. Click on the Advanced button.

Configuration  
The profile setting allows you to save configurations in different profiles for different working  
environments. The default profile will contain the initial configuration setting when you install  
the Card.  
Under the Operating Mode drop-box, you may choose either Infrastructure or Ad-Hoc. The  
Infrastructure mode allows a wireless adapter to communicate with a wired network employing  
an Access Point, while the Ad-Hoc mode allows wireless-to-wireless, peer-to-peer  
communication.  
If you choose Infrastructure, the SSID  
should have the same name as the Access  
Point. If you choose Ad-Hoc, all clients  
should share the same SSID name and  
channel. When using Infrastructure mode  
you do not need to specify channels as the  
NP5420 adapter will select the appropriate  
channel when it finds an access point with  
the same SSID. If two access points are  
broadcasting the same SSID they should be  
on different channels (preferably 2 or more  
apart) and their range should partially  
overlap to avoid 'black spots'.  
Under Power Saving Mode, you can select  
Enabled to allow your adapter to go to sleep mode while the Card doesn’t proceed the data  
transmission. Or select Disabled to make the Card never go to sleep mode.  
Click Apply to save the settings.

Wired Equivalent Privacy (WEP) is an encryption scheme used to protect wireless data  
communication. The Disabled setting prevents the sharing of data with other computers on the  
WEP network. For data sharing to be enabled, select the level of encryption desired, either 64 or  
128-bit.

Appendix A: FAQ  
1. What is IEEE 802.11 standard?  
The IEEE 802.11 is a wireless LAN industry standard, and the objective of IEEE 802.11 is  
to make sure that different manufactures’ wireless LAN devices can communicate to each  
other.  
2. What is WEP?  
As described in the IEEE 802.11 standard, WEP (Wired Equivalent Privacy) is a data  
privacy mechanism based on a 40 bit shared key algorithm.  
3. My desktop PC cannot recognize the Wireless Network PCI Adapter.  
Please make sure that the Card is inserted into the PCI slot of your desktop PC properly  
(check this when the PC is powered off).  
And also make sure that the PCI controller is enabled in the BIOS of your desktop PC.  
Try installing the card in a different PCI slot.  
4. In Infrastructure mode, my desktop PC cannot communicate with the others PCs on  
the network.  
First, make sure that the SSID is same as the others PC.  
Check if the WEP is enabled on the Access Point, if it is, set your Adapter’s WEP the same  
as the Access Point.  
Also check the Access Point’s Authentication Type and Preamble Type and match those  
settings.  
5. In ad-hoc mode, my desktop PC cannot communicate with the others PCs on the  
network.  
Make sure the SSID and the Channel number are the same as other wireless stations.  
Check if WEP settings are the same in all wireless stations.  
Check the Network Properties, make sure proper protocol is installed and File and Printer  
Sharing is enabled.

6. The serial number has been defaced or altered in any way or if the serial number plate has  
been removed.

legalisation of another Government (“the relevant acts”) in certain circumstances imply  
mandatory conditions and warranties which cannot be excluded. This warranty is in addition to

To the extent permitted by the Relevant Acts, in relation to your product and any other materials
