If the icon is in red, it means that Wireless LAN 11Mbps NIC configuration is invalid or incomplete. Sometimes icon can be colored in red. This canhappen when driver is in Pseudo BSS mode, and the radio channel, which is used for communicationis defined incorrectly. Figure 1 Icon tray with a new icon Double clicking on that icon will show you the screen as shown below. Figure 2 Management window with “Status” tab open User can navigate through “sheets”, by clicking or tapping them with a stylus. “OK” button will minimizewindow, and “Cancel” (or X button) will close application. Here we explain the use and meanings ofthe various screen messages.
Wireless LAN User manual Wireless LAN 11 Mbps Page 19Link Info- StateThis field is used to display the current state of the driver. When the state is “Associated “ meansnormal flow of operation in Infrastructure mode. The PC is connected to access point. BSSID isshown in the form of hex digits. Networking is available. A state of “Scanning ” means that the node is searching for available access point and can not detect the SSID for an access point within range.This field will also display an error message if for some reason the driver failed to initialize.- Rescan Pressing the rescan button causes the driver to restart and begin its Connection Procedure. The connection procedure differs depending on the Mode of the driver.Infrastructure Mode - The driver will scan all available channels continuously until it finds one ormore Access Points that matches its SS ID. At that point it will try and authenticate and associatewith the Access Point. Ad Hoc Mode - The driver will scan for 5 seconds looking for an existing Ad Hoc network using the same SS ID. If one is not found the driver will start its own Ad Hoc network.- Current Channel and Tx Rate Shows the channel of the radio and transmit rate are being currently used for an active connection. This value has no meaning when the radio is “Scanning”- Throughput These two fields display the instantaneous wireless Receive and Transmit throughput displayed in bytes per second. These values are updated every two seconds.- Link QualityThe Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graphdisplays the quality of the link between the node and its Access Point. A label summarizes thequality of the link over the bar graph, which can take on one of the following values:“Poor” “Weak”“Fair”“Good”“Excellent”
Wireless LANPage 20 Wireless LAN 11 Mbps User manualThe driver will start looking for a better Access Point if the Link Quality becomes “Poor”. Link Qualityis a measure of receives and transmits errors over the radio.- Signal Strength The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar graph displays normalized signal strength as reported by the radio, averaged over all frames over 100 bytes long that are received from the Access Point.
Wireless LAN User manual Wireless LAN 11 Mbps Page 21 “CONFIGURATION” tabThe Configuration Tab contains several fields where operating parameters of the drivercan be viewed or changed. Changes to any of the parameters in this panel can beapplied to the driver without the need to reboot the PC. Figure 4 Management window with "CONFIGURATION" tab open Restore Defaults:Pressing this button restores each field in the panel to its default value. The ApplyChanges button or OK must be pressed before the default values are saved to thedriver and registry.Undo Changes: Pressing this button reverts all fields in the panel back to their original values that were present when the Configuration Utility was opened from the Task Bar.Apply Changes: This button becomes active only when one of the fields has been modified. Pressing this button applies the changed values to the driver and saves them to the registry for the next time the PC boots up.
Wireless LANPage 22 Wireless LAN 11 Mbps User manual- Mode This field allows you to select from a list of supported Network “Modes”. The modes displayed willhave three values: “802.11Ad Hoc”, “ Ad Hoc”, and “Infrastructure”.802.11 Ad Hoc - This is the 802.11 peer-to-peer mode of operation. In 802.11Ad Hoc only onewireless “cell” is supported for each different SSID. All communication is done from Client to Clientwithout the use of an Access Point. 802.11 Ad Hoc networking use the same SSID for establishingthe wireless connection.Ad Hoc - A non-compliant mode that will allow Prism2 (and only Prism2) cards to talk with oneanother without an AP regardless any SSID. Since it is not standards compliant, It would have theinterpretability with non-Prism2 radios. Infrastructure - This mode of operation requires the presence of an 802.11 Access Point. Allcommunication is done via the Access Point, which relays packets to other wireless Clients inthe BSS as well as to nodes on a wired network such as Ethernet. TX Rate – The transmission rate at which the data packets are transmitted by client of AP. You canset this to fixed 1Mbps, fixed 2 Mbps, fixed 5.5 Mbps or 11 Mbps. PS Mode - Power saving mode.
Wireless LAN User manual Wireless LAN 11 Mbps Page 23“ENCRYPTION” tab Figure 5 Management window with “Encryption” tab open You may desire an additional measure of security on your wireless network, which can beachieved by using WEP (Wired Equivalent Privacy) encryption. WEP encrypts each frametransmitted from the radio using one of the Keys entered from this panel.When an encrypted frame is received it will only be accepted if it decrypts correctly. This will onlyhappen if the receiver has the WEP Key used by the transmitter.This panel allows the entry of four keys for 64-bit encryption and one set of 128-bit key accordingto WEP function select. To be written to the driver and registry, each key must consists of hexdigits which means that only digit 0-9 and letters A-F are valid entries. If entered incorrectlyprogram will not write keys to a driver.Alternatively a Pass-phrase can be entered which is used as a “seed” to randomly generate thefour keys. This saves considerable time since the same keys must be entered into each node onthe wireless network.
Wireless LANPage 24 Wireless LAN 11 Mbps User manual- Key 1 – Key 4These four fields can be used to manually enter the keys. This may be necessary if you wishthis node to match keys in a different vendor’s product. These fields also display the keys whenthey are generated using a Pass-phrase.- Default Tx KeyThis button updates the driver with the four keys displayed in Key1 through Key4. The keys arealso written to the registry for permanent storage. For 128 bit encryption, this button will beinvisible.- ApplyThis button updates the driver with the four keys displayed in Key field. The keys are alsowritten to the registry for permanent storage. This button clears all the bytes in the four keys,useful when manually entering and you wish to start over.
