1 INTRODUCTION Thank you for purchasing the Belkin Wireless USB Network Adapter (the Adapter). Now you can take advantage of this great new technology and gain the freedom you need around the home or office without using cables. The Wireless USB Network Adapter works like a conventional network adapter, but without the wires. The easy installation and setup will have you networking wirelessly in minutes.
Applications and Advantages • Wireless roaming with a laptop around the home or office Offers the freedom of networking—without cables. • Difficult-to-wire environments Enables networking in buildings with solid or finished walls, or open areas where wiring is difficult to install. • Frequently changing environments Adapts easily in offices or environments that frequently rearrange or change locations.
ADAPTER 3 Status Light Indicates network activity and power Adjustable Antenna PLACING THE WIRELESS USB NETWORK ADAPTER 4 The best location for your adapter is on top of your computer’s monitor. Placing the Adapter on your desktop is acceptable, however, avoid placing the Adapter near metal objects such as a computer case or speakers. Any object that is metal has the ability to block the radio signals from the Adapter.
Software and Driver Installation 1. Insert the CD into your CD-ROM drive. 2. The Belkin Wireless USB Network Adapter Setup Utility screen will automatically appear. If it does not appear within 15–20 seconds, then select your CD-ROM drive and double-click on the folder named “Files”. Next double-click on the icon named “USB_UTILITY.exe”. 3. In the menu window, drag your mouse over the “Install” button then select “Click here” to start the software installation program.
6. After connecting your Adapter, Windows will detect that new hardware has been installed. Depending on your version of Windows, a window similar to the one pictured here will appear. Select the option “Install the software automatically (Recommended)”.
ADAPTER 6 7. If you are using Windows 2000 or Windows XP, you may see a screen similar to this one. This does not mean there is a problem. Select “Continue Anyway”. 8. If you are using Windows 98 or Me, you will be asked to restart your computer. Select “Restart”. If you are using Windows 2000 or XP, you will see a window similar to this one. Click “Finish”.
ADAPTER 7 9. When the installation is complete, the Belkin WLAN Monitor icon will be on your desktop. To open the Monitor Utility, double-click on this icon. 10. A small icon in your system tray (bottom right corner of most screens) will appear. This is your shortcut to the Belkin WLAN Monitor. It also indicates the status of your connection: Red: No connection to a wireless network Blue: Connected to a wireless network.
8 If you already have a wireless router or an access point in your home or office, the Adapter will automatically attempt to connect to your wireless network. In most cases, the Adapter will be able to connect to your network automatically. If your wireless network is using encryption, you will need to set the encryption settings of your Adapter to match that of your wireless network. For information about configuring your Adapter, see the next section in this manual.
The Status Tab USING THE BELKIN WIRELESS LAN MONITOR UTILITY 10 HE BELKIN WIRELESS LAN MONITOR UTILITY 11 (a) Profile Name The first thing you will notice is the “Profile Name”. Initially this will say “default” and be grayed out until you have set up a profile. Also, the Profile Manager Mode (k) will be “OFF”. Using Profiles allows you to save configurations for different wireless networks.
(c) Channel Shows the current channel the Adapter is operating on. When operating in Infrastructure mode, the channel is set automatically by the access point or wireless router that the Adapter is connected to. You cannot change the channels in Infrastructure mode. In Ad-Hoc mode, the channel can be set manually. For more information about operating in Ad-Hoc mode, see “Operating in Ad-Hoc Mode”. (d) SSID The SSID is the wireless network name.
signal quality. Fixed 1Mbps—Always transmit and receive at 1Mbps data rate regardless of signal quality. Auto—Adjust speed according to signal strength. This mode is the recommended setting. It will decrease the amount of transmit and receive errors by reducing the speed of transmission in favor of receiving error-free data. Note that data being sent at Fixed 11Mbps with low signal quality will not necessarily get the data to the computer faster. This is because when errors occur, the data must be resent.
13 (i) Link Quality Displays the quality of the wireless signal from 0 to 100%. The closer to 100%, the better the link quality is. Link quality differs from signal strength by measuring the actual quality of the signal. It is possible to have low signal strength and high link quality. (j) Activate Profile Manager Mode See the section called “Using Profile Manager Mode”. (l) Exit Button Click “Exit” to close the Wireless LAN Monitor Utility.
(b) SSID The Service Set Identifier (wireless network name) of the access point. cbedaf g USING THE BELKIN WIRELESS LAN MONITOR UTILITY 16 (c) Signal The signal strength of the related access point. This is a “snapshot” of the signal strength at the time of the site survey. Pressing the “Re-Scan” (g) button may get a different result. (d) Channel The current operating channel of the access point.
“Key 1” through “Key 4”. Only one key can be used at a time. For ease of use, the software can generate keys using a passphrase that you enter. This passphrase can be easily distributed to other wireless-equipped computer users in your network. For instance, creating a key using the passphrase “Passphrase” generates four keys in 64-bit encryption mode and one key in 128-bit encryption mode.

Select “64-bit” or “128-bit” encryption from the drop-down menu. 2. Select “Manual Entry” then “Alphanumeric: 5 characters” if using 64-bit or “Alphanumeric: 12 characters” if using 128-bit. Enter up to four keys. 3.
4. Click “Apply”. Encryption is now enabled. Each wireless-equipped computer (client) that needs to communicate on the wireless network must be set to the same encryption settings (rate, passphrase, and key). 20 USING THE BELKIN WIRELESS LAN MONITOR UTILITY 21 The Advanced Tab The settings on the “Advanced” tab should be left as is unless there is a specific reason to change them.
