Wireless Network 2,4Ghz PCI Card adapter 140M

WL-141

Quick Installation Guide

Introduction The Wireless adapter is an IEEE 802.11G compliant wireless LAN adapter. It fully supports wireless networking under Windows 98, ME, 2000 & XP with a maximum transfer rate of 140Mbps. The Wireless adapter can operate in Ad-Hoc or Infrastructure network configurations. Ad-Hoc mode allows the Wireless Cardbus PC-Card users to join a Basic Service Set (i.e., peer-to-peer mode, without an access point). Infrastructure mode allows the Wireless Cardbus PC-Card users to join an Extended Basic Service Set (i.e., connect to an access point) Wireless LAN (Local Area Network) systems offer a great number of advantages over a traditional wired system. Wireless LAN’s (WLAN’s) are more flexible, easier to manage and often more cost effective then their wired equivalence. Using radio frequency (RF) technology, WLAN’s transmit and receive data over the air, minimizing the need for wired connections. Thus, WLAN’s combine data connectivity with user mobility and through simplified configuration enable moveable LAN’s

4. File and Printersharing Windows 98/ME To enable File and Printersharing on your network, Right click the icon 'Network Neighbourhood' on the desktop, choose 'properties'. Click the ‘file and printersharing” button. Simply click the two boxes you see in the resulting dialog box, then click OK. But before you reboot your computer, you'll need to check a few other settings.

• Click the Identification tab in the Network Control Panel. Enter a unique COMPUTERNAME, and a brief description of your computer in the Computer Description slot. The WORKGROUP name you assign to each computer must be exactly the same for every computer on your network.

• Sharing Files and folders: When you want to share a hard drive (or any other storage device) on one machine with all of the other machines on the network, simply right-click the drive letter or folder you wish to share, then select Sharing from the pop-up menu. After you select Sharing, you'll be presented with a dialog box containing several options. Type in the Share Name, add a comment, and set the access type. If you choose Read Only, other computers on the network will be prevented from copying files into the shared drive or folder. If you select Full, any machine on the network will be able to write to them as well.

• Sharing printers: Click ‘start’, ‘settings’, and ‘printers’. Right click the printer you want to share on the network and choose “sharing”. In the following screen enable sharing and fill in a sharename, the printer is now shared. To use the network printer on other PCs in the network, it has to be installed on the other PCs first. Click ‘start’, ‘settings’, and ‘printers’. Click the ‘Add New Printer’ icon. The ‘New Printer Wizard’ starts. Choose ‘network printer’. In the following screen browse to the correct printer via network environment. The printer will now be installed. Repeat this steps for all PC’s in the network. The printer can now be used from every PC in the network.

Windows 2000/XP File and Printer sharing will be installed automatically under Windows 2000/XP. Sharing files, folders and printers is the same as under Windows 98/ME, however assigning the computer and workgroup name as in step one is different. Windows 2000 Right click the ‘My Computer’ icon on the desktop, choose ‘properties’. Click the ‘computer name’ tab. Fill in the COMPUTERNAME and the WORKGROUPNAME by the same specifications as Windows 98/ME Windows XP Click ‘start’. Right click the ‘My Computer’ icon, choose ‘properties’. Click the ‘computer name’ tab. Fill in the COMPUTERNAME and the WORKGROUPNAME by the same specifications as Windows 98/ME. Guest Account Windows 2000 When you want to reach a shared file or folder in the network on a Windows 2000 machine, most of the time you are requested for a password. This is due to the fact the

so called 'Guest account' in Windows 2000 is disabled by default. You can enable the guest account:

• Right-click 'My Computer', and then click 'Manage'. • Under 'System Tools', double-click 'Local Users and Groups' to expand it, and then

click 'Users'. In the right screen, right-click the 'Guest' account, and then click 'Properties'. Click to clear the 'Disable this account' check box and click OK.

• Click 'start/settings/control panel/Users and Passwords'. • Select 'Guest' and click the 'set password' button. • Make sure the password is set to null (blank).

5. Security To prevent unauthorized accessing the transmitted data over your network, the WLAN Utility offers sophisticated security options. To activate the security options, click the checkbox next to Security.

5.1 Small Office – Home (SoHo) WEP (Wired Equivalent Privacy)

This is the first and most used encryption mode for wireless networks and can be used in peer to peer networks and networks which use a Accesspoint.

Make sure the same key is used on all wireless stations. Choose either Open or Shared for Authentication Mode and WEP for Encryption Mode.

Open key authentication involves supplying the correct SSID. With shared key authentication, the AP sends the client device a challenge text packet that the client must then encrypt with the correct WEP key and return to the AP. If the client has the wrong key or no key, authentication will fail and the client will not be allowed to associate with the AP. Shared key authentication is considered less secure, because a hacker who detects both the clear-text challenge and the same challenge encrypted with a WEP key can decipher the WEP key. With open key authentication, even if a client can complete authentication and associate with an AP, the use of WEP prevents the client from sending data to and receiving data from the AP, unless the client has the correct WEP key. Next configure the Pre-configured key (WEP) section

Choose the format for entering the key, either Hexadecimal, Alphanumeric (ASCII) or PassPhrase.

Choose the key number you want to use.

Choose the encryption length, 128 bits is best

Enter the Network Key. Depending on the type you choose (ASCII or Hexadecimal, 64 or 128 bits), the length of the key could be 5,10,13 or 26 characters.

alphanumeric 5 characters A-Z & 0-9 64 bit hexadecimal 10 characters A-F & 0-9 alphanumeric 13 characters A-Z & 0-9 128 bit hexadecimal 26 characters A-F & 0-9

The PassPhrase is a convenient way to generate a key. You can a normal sentence. The utility will convert this into a security key. (Only use this option when all wireless products are from the same manufacturer). WPA-PSK (Wi-Fi Protected Access-Pre Shared Key)

WPA is a big improvement for Wireless security compared to WEP and can be used in networks which use an accesspoint. WPA normally use a Authentication server in the network for secure access. For home use WPA-PSK was developed. There is no need for an authentication server.

With WPA-PSK the client authenticates to the Accesspoint with the pre shared key (just like WEP). When the connection is approved the data is transmitted encrypted with a key derived from the pre shared key. The final encryption key is therefore different from the pre shared key.

Choose WPA-PSK or WPA-NONE for Authentication and TKIP for Encryption Mode.

Enter the Network Key in the Pre-configured key (WPA) section. It should be an alphanumeric password phrase between 8 and 63 characters.

5.2 Enterprise organisations Please refer to the manual on CD-Rom.

Large organisations sometimes demand extra safety requirements for wireless network connections. Most of the time an Authentication server (Radius server) is used in such a network.

The WL-022 supports two options for this kind of security: 802.1x and WPA. Contact your network administrator for the correct settings.

IEEE 802.1x Authentication

802.1x is an enhancement for the traditional WEP security. If the Authentication mode is either Open or Shared it’s possible to enable IEEE 802.1x authentication for this network.

Depending on the information from the network administrator choose the correct EAP (Extensible Authentication Protocol) type.

If the Authentication mode is set to Open you’ll have the possibility to enable Keys will be generated automatically for data privacy. When disabled or if the Authentication mode is set to Shared you’ll need to fill in the Pre-configured key [WEP] (See chapter 5.1 WEP).

WPA WPA is a big improvement for Wireless security compared to WEP. WPA use an Authentication (radius) server in the network for secure access.

Choose WPA for Authentication and TKIP for Encryption Mode.

Depending on the information from the network administrator choose the correct EAP (Extensible Authentication Protocol) type.

Certificate Information

With 802.1x and WPA Certificate Information is needed. After configuration of 802.1x or WPA, click Next.

The configuration depends on the EAP type and information from your Network Administrator. TLS requires the entry of Certificate Information and Login Information for mutual authentication. When security requires TLS, you should select the appropriate information in the following field using drop-down menu:

User Certificated: select one of user certificates you have enrolled.

Certificate Authority: select one of certificate authorities you have registered.

Login Information: this menu lets you enter a Server Name and Login Name to authenticate

PEAP requires the use of certificates with a Certification Authority server. Click the up and down arrows to the right of this list to display all the Certification Authority types. Highlight one of certificate authority to select it. You also need to input the User Information and the Login Information in the appropriate fields.

LEAP requires the mutual authentication between client adapters and access points. You must present a User Name and Password that will be verified by a LEAP-capable RADIUS server. This mutual authentication ensures that only authorized users are allowed access to the network.

6. Wireless Configuration Utility You can easily navigate through the sheets by clicking the different tabs.

6.1 Link Information Click 'More…' for more information about the wireless connection.

Connected to Network This field is used to display the current status of the wireless connection. When the utility shows 'Connected to network' it means that the network is available in Infrastructure or Peer to Peer mode. If the utility shows 'Scanning' it means that the node is searching for available access points or wireless adapters.

Network Type Infrastructure mode: The driver will scan all available channels continuously until it finds one or more Access Points that match the Network Name (SSID). At that point it will try to authenticate and associate with the Access Point. Peer to Peer mode: The driver will scan for 5 seconds looking for an existing Ad Hoc network using the same Network Name (SSID). Channel, Link Speed & Encryption The channel and the transmit rate used to connect to an active wireless network. Encryption shows the status of the encryption level.

Signal Strength The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar graph displays the signal strength between the node and the Access Point. Link Quality The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph displays the quality of the link between the node and the Access Point.

6.2 Available Networks The Available Networks tab shows the current status of all available wireless networks.

Select a Network Name (SSID) from the list, click 'Connect' to connect to the wireless network. The 'Refresh' button will rescan the network and it will detect and list all available wireless networks.

5.3 Profile Setting The Profile Setting allows users to create profiles for different network environments.

Click the 'New' button to create new profiles. Click 'Edit' for editing existing profiles. Click the 'Delete' button for deleting profiles.

Network Type This allows you to select 'Peer to Peer' mode or 'Infrastructure' mode.

Peer to Peer: All communication is done from client to client without the use of an Access Point. Ad-Hoc networking uses the same Network Name (SSID) for establishing the wireless connection. Infrastructure: This mode requires the presence of an Access Point. All communication is done via the Access Point which relays packets to other wireless clients in the BSS as well as to nodes on a wired network. Transmit Rate The transmission rate at which clients or Access Points transmit the data packets. Security See chapter 5 for additional information

IP Setting With this option the wireless adapter can be configured with a static or a dynamic IP address, a default gateway and a DNS Server address.

6.4 About The 'About' tab shows the Utility Version, Driver Version, Firmware Version and the MAC Address.
