(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. For instance, if you use your Adapter at your place of work and also at your home, your wireless network settings may be different for each location. Profiles let you store settings for each location and name them for easy identification. The default profile will contain the initial configuration setting when you install the Adapter. To learn how to use Profiles, see the section of this manual called Using Profile Manager Mode.
(b) Operating Mode Shows the current wireless mode the Adapter is operating in. There are two operating modes: Infrastructure and 802.11 Ad-Hoc. Infrastructure is the most common mode to operate in and is the factory default setting. Use Infrastructure mode when connecting your PC to a wireless access point or to a wireless router. Ad-Hoc mode is used to connect two or more computers together without the use of an access point or wireless router. To change the mode, click the down-facing arrow next to the Operating Mode field. Select the mode you wish to use, then click Apply.
(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. This field shows the current SSID with which the Adapter is associated. The default (factory) setting is ANY, which will cause the Adapter to automatically look for any wireless network in the area. To connect to a specific wireless network, you can manually enter the SSID of the known wireless network. Note that the SSID is case-sensitive, so, capital letters do make a difference. To change the SSID, click in the SSID field, type the SSID you want, then click Apply. USING THE BELKIN WIRELESS LAN MONITOR UTILITY 12
(e) Tx Rate Displays the current rate of data transmission. There are five Tx rates possible:
Fixed 11MbpsAlways transmit and receive at 11Mbps data rate regardless of signal quality. Fixed 5.5MbpsAlways transmit and receive at 5.5Mbps data rate regardless of signal quality. Fixed 2MbpsAlways transmit and receive at 2Mbps data rate regardless of signal quality. Fixed 1MbpsAlways transmit and receive at 1Mbps data rate regardless of signal quality. AutoAdjust 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. When the signal quality is low, the chances for errors to occur at high speeds are greatly increased. Sending the data at lower speeds when the signal quality is poor will reduce the chances of errors, and thus data will get to the computer in the shortest possible time.
(f) MAC Address Shows the MAC address of the Wireless USB Network Adapter.
(g) Status Displays the BSSID (in hexadecimal) of the access point with which the Adapter is associated. If you are connected to a network, the word Associated followed by a series of numbers (the MAC address of the access point) will be displayed. If the Adapter is scanning for a network, you will see the word Scanning.
(h) Signal Strength Displays the strength of the wireless signal from 0 to 100%. The closer to 100%, the better the signal strength is. The closer you are to a wireless router or access point, the stronger the signal should be. USING THE BELKIN WIRELESS LAN MONITOR UTILITY 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. To access the utility again, double-click on the icon in the bottom right corner of your screen. USING THE BELKIN WIRELESS LAN MONITOR UTILITY 14 The Statistics Tab The Statistics tab shows you how much data has been sent and received and if any errors occurred. Click Reset (a) to start at zero. This screen is mostly for diagnostics. Note that the number of unsuccessful data and management frames is recorded. A large number of unsuccessful frames may indicate that there is a problem or interference in your area. a USING THE BELKIN WIRELESS LAN MONITOR UTILITY 15 The Site Survey Tab Clicking on the Site Survey tab will display a list of all available access points in your area. The following information about each is displayed:
(a) BSSID The MAC address of the access point.
(b) SSID The Service Set Identifier (wireless network name) of the access point. c b e d a f 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.
(e) Encryption Will display No when encryption is disabled, 64-bit when 64-bit encryption is enabled, and 128-bit when 128-bit encryption is enabled.
(f) BSS Displays the mode that the access point is operating in: Infrastructure or AD-Hoc. TIP: Double-clicking on the BSSID of an access point will make the Adapter join that particular network. To check the area for more access points, click Re-Scan. USING THE BELKIN WIRELESS LAN MONITOR UTILITY 17 The Encryption Tab The Encryption tab is used to set up the wireless encryption settings. There are two ways to set up the encryption settings of your Adapter:
Create with Passphrase or Manual Entry. Select 64-bit from the drop-down menu. You will notice when using 64-bit encryption that there are four keys labeled 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. In this scenario, a user of a laptop needs only to enter the passphrase and the key number into the computers wireless management software to be able to communicate while using encryption. All computers on the network must use the same encryption rate, passphrase, and key. The passphrase can be changed as often as desired. USING THE BELKIN WIRELESS LAN MONITOR UTILITY 18 Setting 64-Bit or 128-Bit Encryption Using a Passphrase
(Easiest) 1. Select 64-bit or 128-bit from the drop-down menu (a). 2. Select Create with Passphrase (b). 3. Enter a passphrase and click Generate (c).
