Bewan Wi-Fi USB 54 14
Configuring the Bewan Wi-Fi USB 54
The following chapter describes how to use the utility to configure your adapter, as well as the
advanced functions. This utility allows rapid access to all of the adapter’s parameters.
After installation of the driver, an icon appears in the task bar. Double-click on this to open the
utility’s main menu.
Note: if the icon does not appear, click on start, go to All Programs, Wireless 802.11g USB
Adapter, then click on Wireless Monitor. Double-click on the icon to launch the utility.
The icon’s colour indicates the current status of your connection:
Red Blue
Æ
No connection to
the Wireless network Connection to the Wireless network established
Configuration procedure:
The configuration procedure for the client workstation is relatively simple:
1. Initial search for an Access Point (“Infrastructure” mode) or for client stations present on the
network (“Ad-Hoc” mode),
2. Configuration of the Wireless connection.
3. Association and authentication with the Access Point or the chosen client workstation.
The operating modes
The 802.11 standard defines two operating modes for the Bewan Wi-Fi USB 54 adapter. The mode
to be selected depends on the wireless network’s configuration type:
•Infrastructure mode, in which the client workstations equipped with the Bewan Wi-Fi USB 54
are connected to an Access Point. This is the default mode at the time of the adapter’s
installation.
•Ad-Hoc mode, to connect directly to another Wireless workstation without an Access Point.

Bewan Wi-Fi USB 54 15
Infrastructure mode
In this mode, the wireless network consists of at least one Access Point (also called a hub),
connected to the infrastructure of the wired network and a series of wireless network workstations
(the client workstations). These workstations (desktop or laptop PCs), fitted with a USB adapter and
possibly also with Wireless cards, are connected to the Access Point that serves as the bridge
between the wired network and the wireless client workstations.
Thanks to a much broader operating perimeter, the Access Point will allow you to extend the range
of communications and to authorise the connection of a much greater number of users. Given that
the Access Point is fixed, the network’s radius is easy to identify.
In case of mobile users, the workstations can easily be moved around within the cell that
corresponds with the area covered by the Access Point. Through the Access Point, the wireless
users will be able to communicate with one another and with the wired network.

Bewan Wi-Fi USB 54 16
Configuration
Once the utility has been launched, proceed as follow:
1. Click on the AP List tab. This tab lists all of the other available Wireless devices to which you
can connect, as well as their characteristics (MAC address, Signal strength, Channel used, usage
or not of Encryption WEP, operating mode). If an Access Point is already configured, it should
now be detected and made available.
Note: click on the Refresh button to update the information displayed.
2. According to the Network Name, click on the identification value for the Access Point to which
you wish to connect, then click on the Connect button (or double-click on the Network Name).
3. When a circle appears in the Access Point icon, this means that your wireless connection is
established with the remote Access Point.
Note: your adapter connects to the Access Point on the communication channel it has set.
Likewise, the transfer rate used corresponds to that indicated by the Access Point.

Bewan Wi-Fi USB 54 17
4. To obtain information about the Access Point in question, click on the Link Information tab.
The following screen appears.
5. Click on the More… button. The window will display the current connection parameters
(network name, operating mode, channel used, encryption activated or not, rate of
transmission).

Bewan Wi-Fi USB 54 18
Ad-Hoc mode
In this mode, the client workstations (at least two) communicate directly with one another, with no
Access Point or connection to a wired network. This mode provides for quick and simple creation
of a wireless network in locations where there is no wired infrastructure or when access to the wired
network is forbidden. This is referred to as a peer-to-peer architecture.
The connection’s speed will depend on the distance between the various stations and on the type of
building in which the network is installed. Given the absence of relays (as the network does not
require an Access Point), the operating perimeter is smaller. This operating mode is more suited to
short distances, and for when the users are not moving around during the transmission.
Required configuration:
When two machines are in the same perimeter, they must recognize each other in order to exchange
data. The parameters must therefore be the same on all workstations if the wireless network is to
operate. All of the workstations must:
•be configured in “Ad-Hoc” mode,
•use the same network name (SSID parameter),
•select the same communication channel,
•enter the same encryption key, if they want to use the WEP Encryption in order to secure the
Wireless network.
Note: in this mode, no DHCP server is available. Each workstation on the wireless network must
therefore be assigned a static IP address within the same addressing plan. To configure your
computer, refer to the chapter “Configuration of the computers” on page 24.

Bewan Wi-Fi USB 54 19
Configuration
Once the utility has been launched, proceed as follow:
1. Click on the Profile Setting tab, then on the Add button.
2. In the Profile Name section, enter the name of your new profile. Click on Next.
3. In the Network Name section, enter the identification value for the network to which you wish
to connect.
Note: you must respect case (capitals/lower case).
4. In the Network Type section, select the Peer to Peer operating mode (synonym of Ad-Hoc).
5. In the Transfer Rate section, select the transfer rate. Check that the rate chosen corresponds to
that configured on the remote Wireless station.
6. In the Channel section, select the channel chosen for communication with the remote Wireless
equipment. Then click on Next.

Bewan Wi-Fi USB 54 20
Note: if you wish to connect to one or more client workstation(s), the selected frequency must be
the same on all of the devices connected to the wireless network in order for the connection to
operate.
7. You can now decide whether or not to activate WEP encryption on your adapter. If you activate
WEP encryption, refer to the section “WEP encryption” on page 21.
8. In the IP Setting section, select Enable, then click on Next.
9. In the DHCP Status section, select Disable in order to allocate a fixed IP address to your
Wireless station.
10. In the IP Address and Subnet Mask sections, enter the IP address you wish to attribute to your
adapter and the corresponding subnet mask.
11. Click on the Complete button to validate the parameters in your profile.
12. Once your profile is created, the driver seeks an existing Ad-Hoc network using the same SSID
(Network Name) to establish the connection.
Note: if the remote Wireless device is already configured, it should be detected and available in
the AP List tab. You just need to double-click on the name (Network Name field) of the
corresponding hardware to establish the Wireless connection.
