Figure 3-1. Instant Wireless - Network USB Adapter Properties
You can set the following USB operational parameters:
• Channel: Select the channel to be used. There are 11 channels
available.
• ESSID: Select the ESSID to be used. The ESSID can be either the
ESSID of the access point to which the station will be associated if in
infrastructure mode, or the ESSID of the ad-hoc network in case the
station will operate in ad-hoc mode. In the latter case, all stations
participating in the ad-hoc network should have the same ESSID.
• Fragmentation Threshold: This is the option for the Fragmentation
Threshold activation.
• Network Address: This is a unique MAC address.
• Operating Mode: Infrastructure or ad-hoc.
• Preamble Type: Select either Long, or Short Preamble Type.
• Rate: Select the rate to be used among the following options: 1 Mbps, 2
Mbps, 5.5 Mbps and 11Mbps.
• RTS Threshold: This is the option for the RTS Threshold activation.
• WEP Key: Select which of the 4 WEP keys is going to be used. You
can select None if you do not need WEP encryption.
• WEP KEY #1 - #4 : You can set the value of 4 different WEP keys.
For every station participating in a Network the user must select the same
Channel and Rate (1, 2, 5.5, or 11 Mbps) but a different Network Address
(MAC Address). Also the user can set the Fragmentation Threshold (the
threshold for the activation of the fragmentation mechanism), as well as the
Instant Wireless - Network USB Adapter User Manual
12
RTS threshold (the threshold for the activation of the RTS/CTS mechanism).
Also, the user can select the operating Mode. Two modes are available:
Ad-Hoc Mode and Infrastructure Mode. In Ad-Hoc Mode the wireless
stations can directly communicate, however, in Infrastructure Mode, an
Access Point is necessary. The user can also specify the ESSID (up to 32
characters). The ESSID field is case sensitive. The user can select long or
short preamble as referred in 802.11b specification. Finally, the user can
select among four user-defined WEP keys for encryption e.g. by setting the
WEP Key To Use field to 3, the WEP KEY #3 will be used; by setting it to
None, no WEP encryption will be used.
Please keep in mind that the WEP keys must be in HEX and in two
characters per byte formats e.g. if you want the WEP KEY #1 to be 12345,
then you must set it as 0102030405.
9. Windows 98 copies files to your hard disk drive, and you see the following
screen:
10. Click Finish to complete the installation.
11. When Windows ask you if you wand to restart your system now, press No in
the dialog box and restart you system manually. If you press Yes, it is
possible that the installation will not be completed (this is an operating
system related problem).
3.4 Configuration Under Windows 98

Section 6 - Configuration and Monitor
Application
The Configuration and Monitor Application is a powerful utility that helps you to
configure the Adapter and monitor the statistics of the communication. Unlike
the standard method of configuring the Adapter via the operating system utilities
(e.g. Control Panel), this application permits the dynamic modification of the
configuration parameters while the Adapter is operating. It also offers some
more configuration options.
The Adapter offers the Configuration and Monitor Application for Windows 98,
Windows 2000 and Windows ME.
Note: Please keep in mind that the Configuration and Monitor Application can
be used to change the above configuration parameters when the Adapter is
active. When the Adapter is not in use, please use the Control Panel method
described in previous sections.
6.1 How to Install the Configuration and Monitor
Application
In order to setup the Configuration and Monitor Application, run the program
SETUP.EXE, which you will find in the Config_Utility folder of your installation
CD and follow the instructions as they appear on the screen. As soon as a link is
established, the application will start running and will appear as an icon on the
system tray. You can locate the application under Start -> Programs -> Instant
Wireless - Network -> Instant Wireless - Network USB Adapter
Configuration.
6.2 Using the Configuration and Monitor Application
The Configuration and Monitor Application appears as an icon on the system
tray of Windows every time the Adapter is running. You can open it by double-
clicking on this icon. While the station is in infrastructure mode and not
associated to an access point, the color of the icon is red. As soon as the station
associates itself to an access point, the icon color turns to blue. In ad-hoc mode
the color is always blue, except when the card is reseting where it turns to red
during the reset procedure.
A typical screen of the application in infrastructure mode is shown in Figure 6-1.
The configuration parameters are shown at the top of the screen, while the
statistics of the communication are shown at the bottom. In the middle of the
screen there is information about which Access Point the Adapter is associated
with, the address of the AP, its SSID and the channel. The four LEDs at the
Instant Wireless - Network USB Adapter User Manual
25
bottom of the dialog box indicate which of these features are enabled.
Figure 6-1. A typical screen of the Configuration and
Monitor Application in infrastructure mode.
A similar screen appears in case the Adapter operates in ad hoc. In this case,
Short Preamble has been enabled (Figure 6-2).
Instant Wireless - Network USB Adapter User Manual
26
Figure 6-2. A typical screen of the Configuration and
Monitor Application in ad-hoc mode.
By pressing the Change button in any of the two modes, you can change basic
configuration settings such as the Operating Mode, Channel, SSID, and
Transmission Rate (Figure 6-3). While in infrastructure mode you can select a
preferred Access Point (AP) by checking the Enable check box and giving the
MAC address of the AP. In that case you must also specify the channel the
preferred AP is using.

Figure 6-3. Change of basic configuration.
By pressing the Advanced button in any of the two modes, you can change
advanced configuration settings, such as the Preamble Type, Fragmentation
Threshold, and RTS/CTS Threshold (Figure 6-4). Figure 6-4 shows the
recommended configuration for the advanced settings. Before selecting Short
Preamble, make sure that the other stations and APs are also supporting this
feature.
