1 Introduction Thank you for purchasing the LevelOne MIMO Wireless LAN PC Card. With the MIMO technology, this card enables you to connect to wireless networks at farther distances than before. The card has two internal antennas for signal reception and one internal antenna for high power si gnal transmission.
1.1 Features • Works with both IEEE 802. 11b and IEEE 802.11g products. • High-speed transfer data rate. • Farther coverage, less dead spaces and highe r throughput with MIMO (Multiple Input Multiple Output) technology. • Supports Turbo Mode to enhance the data transfe r speed within the specific wirel ess network.
1.3 Package Contents Before you begin the inst allation, please check the items of your p ackage. The p ackage should include the following items: • MIMO Wireless PCMCIA Adapter • CD (Driver/Utility/User Manual.) • Quick Guide If any of the above items is missing, contact your supplier as soon as pos sible.
2 Installation Procedure Before you proceed with the inst allation, please notice following descriptions. Note1: Please do not install the card into your laptop computer before ins talling the software program from the CD. Note2: The following installation was operated under Windo ws XP.
B. Click “Y es” to process the inst allati on if you accept the license agreement. C. In Windows XP , there is a “Windows Zero Configur ation T ool” for you to setup wireless cards. Y ou can choose to configure the card through the “Zero Configuration T ool” or the “LevelOne Configuration T ool” for the card.
D. If you need the card to operate with better performance, plea se choose the “Optimize for performance” to enable the Tx Burst mode. Or you ca n choose “Optimize for Wi-Fi mode” to let the card run in st andard wireless network. E. The system start s to install the sof tware of the card.
F. Please click “Finish” to complete the installation. 7.
3 Configuration Utility LevelOne Configuration Utility is a powe rful applicat ion that helps you configure the PC card and monitor the link status and the statis tics during the communi cation process. When the card is installed, Level One configuration utility will be displayed automatically.
In Windows XP , there is a “Windows Zero Configuration T ool” for you to setup wireless client s. If you want to switch the configuration utilities, please follow one of the ways as bel ow . First Way Right click the icon in the system tray and select “Use LevelOne Config as Configuration Utility”.
C. Uncheck “Use Windows to config ure my wireless network settings” to enable the utilit y for the card. Note: If “Wireless Zero Configuration” is enabled, y ou can only configure the advance setting or check the link status and statistics from t he configuration utility of the card.
3.1 Site Survey When you open the LevelOne Configuration Utility, the syste m will sca n all the channels to find all the access points/stations within the acce ssible range of your card and automatically connect to the wireless device with the highest sign al strength.
3.2 Profile The “Profiles List” is for you to manage the netwo rks you con nect to frequently. You are able to Add/Delete/Edit/Activate a profile. Parameter Description Profiles List The profiles list display all the profiles and the relative setting s of the profiles including Profile Name, SSID, Cha nnel, etc.
3.2.1 Configure the Profile 3.2.1.1 Configuration Parameter Description Profile Name Define a recognizable profile name for you to identify the dif ferent networks. SSID The SSID (up to 32 printabl e ASCII characters) is the unique name identified in a WLAN.
Point or Router . Ad-Hoc – Select this mode if you want to conne ct to another wireless st ations in the Wireless LAN network without through an Access Point or Router . TX Power If you want to lower the tran smit power of the card for saving the power of the system, you can se lect the lower percent ages from the list.
Fragment Th reshold The value defines the maxi mum size of p ackets; any packet size larger than the value will be fragmented. If you have decrea sed this value and experience high p acket error rates, you can increase it again, but it will likely decrease overall network performance.
server products is not a co ncern. When you have set up LEAP authentication, you have to enter the user name and password of your computer . WP A – WP A provides a scheme of mutual authentication using either IEEE 802.1x/Extensible Au thentication Protocol (EAP) authentication or pre-shared key (PSK) technology .
802.1x Setting When you have set the Authentication T ype to Open, Shared, WP A or WP A2, you can also en able IEEE 802.1x setting to use the authentication server or certif ication server to authenticate client users. Parameter Description Encryption Mode None – Disable the encryption mode.
The IEEE 802.1X specification describe s a protocol that can be used fo r authenticating both clients and servers on a network. The authentication algorithm s and methods are those provided by the Ext.
3.2.1.3 802.1x Setting-Certification Parameter Description Authentication T ype The EAP authentication pr otocol s this card has supported are included as follows. This setting has to be consistent with the wireless APs or Routers that the card intends to connect.
Identity This is the protected us er EAP Identity used for authentication. The identity specified may cont ai n up to 63 ASCII characters, is case sensitive and ta kes the form of a Network Access Identifier , consisting of <name of the user>@<use r ’ s home realm>.
