As our IEEE802.11b USB Adapter is interoperable and compatible with  
other IEEE 802.11b compliant products from other manufacturers, it  
offers you the most freedom to establish your ideal wireless network.  
Therefore, after installing IEEE802.11b USB Wireless LAN, you can  
connect your computer to:  
a. A Peer-to-Peer Workgroup of IEEE802.11b compliant wireless  
devices.  
b. A LAN (Local Area Network) constructed by Access Point(s) or  
other IEEE802.11b compliant systems.  
c. Share your Internet access by using just one connection,  
share printers and other peripheral devices, share data and  
image files between networked PCs, play multi-player games,  
and use other network enabled sharing resources.

1.4 Advantages for Using Wireless  
Network  
IEEE802.11b Wireless LAN can wirelessly transmit and receive data,  
minimizing the need for wired connections, at a speed of up to eleven  
megabit per second. With IEEE802.11b Wireless LAN you can locate  
your PC wherever you want without wires and cables.  
IEEE802.11b Wireless LAN provides LAN users with an access to  
real-time information anywhere in their organization. The mobility  
provides effectiveness and efficiency, which are not available under  
wired networks.  
The IEEE802.11b Wireless LAN configuration is easy to switch between  
peer-to-peer networks, suitable for a small number of users, and full  
infrastructure networks of thousands of users that allow roaming around  
a broad area.  
Therefore, you may see many advantages for adopting Wireless  
Networking as follows:  
-
Less Space Limits: USB Adapter provides access to  
network services without wires; therefore, it gives you more  
freedom to allocate and style your living and working space.  
In addition, in some areas where is hard or expensive to  
connect to wired networks, such as historic buildings,  
classrooms or mobile connectivity, then you can count on  
wireless networking.

-
Flexible Workgroups and Lower Cost: For workspaces that  
are frequently reconfigured for temporarily use such as  
demo in exhibitions, wireless networking is easy to set up  
of lower total cost—and all equipments are recyclable. You  
do not have to remove the old wires and then build up the  
new ones again and again.  
Networked Conference Rooms: Users can access the  
network as they move from a meeting to another, getting  
the access to information/data and the ability to  
communicate decisions while “on the go”.  
-
-
Ad Hoc Networking: On site consulting and small  
workgroups may increase productivity with quick network  
setup and collaboration software.  
Branch office Networking: With an Access Point to bridge  
between the LAN and Internet, wireless networking  
provides an easy to install, use and maintain network for a  
remote or sales office.  
-
Campus-Wide Network Mobility: The roaming capabilities allow  
enterprise to set up easy to use wireless networks that cover the  
entire campus transparently.

3.3.1 Setting  
Operating Mode:  
If you want to connect to an Access Point, please set the mode  
as ”Infrastructure”. If you have more stations and just want to set  
them as a local network, please set the Mode as ” Ad Hoc”.  
Channel:  
It shows the radio channel number that is used for networking.  
The Channel number must be the same among stations, so that  
computers can communicate within the local LAN. It can be  
changed only under the Ad Hoc Mode. If the Mode is  
Infrastructure, this parameter will not be active.  
SSID:  
SSID is the group name shared by every member of your wireless  
network .You will only be able to connect with an Access Point  
(AP), which has the same SSID. Please note that the SSID will be  
case sensitive. Please note that when you are in the Ad-hoc  
mode, the SSID must be the same among stations so that  
computers can communicate within the local LAN properly.  
Tx Rate:  
The USB Adapter supports 4 transmission rates: 1Mbps, 2Mbps,  
5.5Mbps, and 11Mbps. You may set the TX rate manually, or  
select the “Fully Auto” mode to let it run at the most proper rate
