Each equipped with on 802.11B WLAN adapter, connected as an independent wireless LAN.Computers in a specific Ad-Hoc wireless LAN must be configured to share the same radio channel. Ad-Hoc wireless LAN configurations are appropriate for branch level departments or SOHO operations.
The 802.11B WLAN provides access to a wired LAN for wireless workstations.An integrated wireless and wired LAN is called an Infrastructure configuration. A group of 802.11B WLAN PC users and an Access Point compose a Basic Service Set (BSS).Each 802.11B WLAN can talk to any computer in the wired LAN infrastructure via the Access Point. An Infrastructure configuration extends the accessibility of a 802.11B WLAN equipped PC to a wired LAN and doubles the effective wireless transmission range for 2 802.

3-3.2 ADAPTER CONFIGURATION – WINDOWS 98 After successful installation of the 802.11B WLAN and its driver, continue the installation process by configuring the 802.11B WLAN adapter properties. To configure the 802.11B WLAN Adapter complete the following steps : 1.From the Control Panel, double-click the “Network” icon.
2.Select "LAN-Express IEEE 802.11 MiniPCI Adapter" from the list and press the “Properties” button.
3. From the “Properties” menu select the “Advanced” tab.
4. Select “Channel” from the list, and choose a “Value” from the drop down list. FCC regulations require a “Value” between 1 and 11. 5. Select “Network Type”, and choose “Infrastructure” or “Ad-Hoc” as the “Value”.
Note: “Infrastructure” mode allows a wireless adapter to communicate with a wired network, While “Ad-Hoc” mode allows wireless-to-wireless communication. Consult your System Administrator for information about your network communication type. For more information About Infrastructure and Ad-Hoc networks, see Chapter 2 of this manual 6. Select “Power Save Mode” and choose a “Value”. NOTE: To allow uninterrupted data communication, choose “Disabled” as the “Value”.
NOTE: The SSID can have any value, but should have the same value as the Access Point (AP). In Ad-Hoc mode, all clients should share the same SSID 9. Select “Transmit Rate”, and choose a “Value”.
NOTE: Fixed 11 Mb/s is the preferred “Value” for environments where the client has line of sight access and is a short distance away from the AP. Fully Auto is the recommended setting for clients that are farther away from the AP and where there may be interference between the client and the AP. 10. Select “Use Wep”, and choose a “Value”.
NOTE: Wired Equivalent Privacy (Wep) is an encryption scheme used to protect wireless data communication. Selecting “Disabled” will prevent you from sharing data with other computers if your network uses Wep. If your network is Wep enabled, you must choose “64bit” or ”128bit”. Consult your System Administrator for more information about your network type. For more information about Wep, see the chapter entitled “PRISM Configuration Utility” in this manual. 11.
3. Highlight “Protocol” and click “Add” . 4.
5. Select “TCP/IP “ and click “Properties”. Repeat step 2 – 5 to install other protocols such as NetBeui or IPX/SPX. NOTE: The following steps apply to DHCP servers.
specific information regarding your server type, and for help in specifying an IP address if you do not use a DHCP server and must manually enter the IP address and DNS number. 6. Check “Obtain an IP address…” and click “OK”. If you are using a DHCP server the IP address will be entered automatically. 7.

Chapter 4 Installing & Navigating the LAN-Express Configuration Utility 4-1 LAN-Express CONFIGURATION UTILITY - INSTALLATION Insert the LAN-Express Network Configuration Utility disk into an available floppy disk drive. From the "Run" window type "A:\utility \setup.ex e" (where "A" represents a floppy disk drive).
4-2 LAN-Express CONFIGURATION UTILITY - NAVIGATION The following section describes and defines the various functions of the LAN-Express Network Configuration Utility. This utility provides quick access to all adapter settings. After installation is complete, a LAN -Express utility icon will appear in the “Start” ->”Program”->”Wireless LAN Card Utility”->”Wireless LAN Utility” Icon.
The LAN-Express Quality Test: Clicking the Quality Test button in the LAN -Express Utility will open the Quality Test, providing a simple test on two station. While one station Set a Master mode, another station set a slave mode. Master station must set slave station’s Mac Address. If a station is tested under loopback test mode, it should use AP of LAN-Express.
The LAN-Express Card Monitor: Clicking the Card Monitor button in the LAN-Express Utility will open the Card Monitor, It can monitor a physical layer in the Adapter currently. The LAN-Express Configuration: Clicking Config Adapter in the LAN-Expres s Utility will open the Config Adapter, providing quick access to all adapter settings. The following image shows the LAN -Express Configuration Utility. It can change every parameters.
The LAN-Express Card Encryption: Clicking the Card Encryption button in the LAN-Express Utility will open the Card Encryption, An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used to protect your wireless data communications. WEP uses a combination of 64-bit keys,128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each wireless client on the network must use an identical 64-bit key,128-bit key.
The LAN-Express Firmware Upgrade: Clicking the Firmware Upgrade button in the LAN -Express Utility will open the Firmware Upgrade, It can upgrade a firmware of differ version. Configuration: Selecting this tab opens the “Configuration” menu. Here you will find options for configuring your adapter.
Description of Settings Following is an explanation of each adapter setting presented by the “Configuration” menu. Mode: The Mode setting determines the architecture of your wireless LAN. Choose Ad-Hoc or Infrastructure Mode depending on your network type. A brief explanation of each mode follows: § Ad-Hoc: This mode is used for a simple peer-to-peer network. This type of network allows the sharing of local resources only between wireless clients without a wireless Access Point (AP).
communication. In an Infrastructure type network without an Access Point active on the default channel, clients will scan through all available channels searching for a network with matching SSID. § Changing the Channel: Changing the channel is only effective in Ad-Hoc networks. Networks operating in Infrastructure mode automatically scan for a channel. The following table presents contains the operational channel frequency for several countries.
§ 1) Click on the Control Panel and then on PC -Card/MiniPCI. Check whether it has MiniPCI card in one of the sockets or not. If you find “LAN-Express IEEE 802.11 PC-Card Adapter” or “LAN -Express IEEE 802.11 MiniPCI Adapter” in one of the sockets, it means the card is detected properly. If you see the yellow sign of § question-mark(?), the resources are conflicting. § 2)Right click on “My Computer” and the select Properties. Select the device Manager and click on the Network Adapter.
The 802.11b WLAN station cannot communicate with other computers linked via Ethernet in the Infrastructure configuration. Probable Solution: § Ensure that the 802.11B WLAN with which the station is associated is powered on. § Confirm the station is configured with the same operating radio channel as the 802.11B WLAN. If the IDs are different, change the 802.11B WLAN and all the stations within the BSS to another radio channel.
