Wireless LAN, Health and Authorization for use

Radio frequency electromagnetic energy is emitted from Wireless LAN devices.

The energy levels of these emissions however are far much less than the electromagnetic energy emissions from wireless devices like for example mobile phones. Wireless LAN devices are safe for use frequency safety standards and recommendations. The use of Wireless LAN devices may be restricted in some situations or environments for example:

·On board of airplanes, or

·In an explosive environment, or

·In case the interference risk to other devices or services is perceived or identified as harmful

In case the policy regarding the use of Wireless LAN devices in specific organizations or environments (e.g. airports, hospitals, chemical/oil/gas industrial plants, private buildings etc.) is not clear, please ask for authorization to use these devices prior to operating the equipment.

Check the installation

The LEDs of the Wireless LAN Adapter are clearly visible and the status of the network link can be seen instantly:

1. Once the device is plugged to the station’s CardBus/PCI slot, the LED of the

Wireless LAN Adapter will light up indicating a normal status.

2. When the device plugged to the station’s CardBus/PCI slot and the driver was installed, the ACT will start alternate blinking, it means that the device is starting to scan the wireless devices near the Wireless LAN Adapter.

3. While the Wireless LAN Adapter linked up and transmitting data to the Access

Point or to other Wireless LAN station, the Link LED will lighted green.

5

SOFTWARE INSTALLATION

This section will lead you to install the driver and utility of the Wireless LAN

Adapter.

Windows 7/Vista/XP/2000/ME/98SE Utility and Driver Installation

1. Insert the 54Mbps IEEE 802.11g Wireless LAN Adapter Driver & Utility CD-

ROM and the Auto-run program will appear. Alternatively, open a file browser and double click on the autorun.exe file located in the CD directory.

2. If you need to install the driver manually, refer each Windows OS to the following CD-Rom directory path: D:\Driver\<Windows OS>.

Note: (D:\ will depends on where the CD-ROM drive is located and

<Windows OS> will depend on the Windows OS you are using).

3. Click “Install Utility” to install the driver and software. Select 7/Vista/XP/2000 or ME/98 , depending on your operating system, and the install wizard will begin installing the software. Follow the install wizard instructions to complete the installation.

4. Follow the Install Shield Wizard Instructions. Click “Next” to continue and finish it.

7

The installation program will help you to setup the Wireless LAN utility. Be noted

that the Windows XP have its own Wireless Utility; you can either use the utility of Windows XP or the provided utility.

When the Wireless LAN Adapter was installed, you will see the icon on the

Windows task bar. The user can configure the wireless settings using the Wireless

Adapter Configuration Utility. Double-click the utility icon that appears in the taskbar

When the icon in the toolbar represents in full green color then the signal strength has an excellent performance with the AP, if it represents in yellow color then the signal strength has a fair performance with the AP, and if the icon represents no color, then the signal strength has a worst performance with the wireless station.

Configuration

This screen is where changes the basic wireless settings for the wireless LAN adapter with the minimum amount of effort to implement a secure wireless network environment.

SSID: Service Set Identifier, which is a unique name shared among all clients and nodes in a wireless network. The SSID must be identical for each clients and nodes in the wireless network.

Wireless Mode: There are two types available for selection

●Infrastructure – to establish wireless communication with LAN and other wireless clients through the use the Access Points.

●Ad-Hoc – to establish point-to-point wireless communication directly with other wireless client devices such as wireless network PCI Adapter.

AdHoc Band: When using Wireless Mode for Ad-Hoc mode, select the AdHoc

Band from drop down list for 11b only, 11g only or Auto for both of 11b and 11g.

Channel: The channel the AP operates on. The channel range of 1 to 11 for North

America (FCC) domain and 1 to 13 for European (ETSI) domain and 1 to 14 for

Japanese domain.

WARNING: Country domain can't be choose by enduser, because the incorrect region may be in violation of applicable laws.

16

Power Mode: There are 3 modes to choose from.

• Continuous Access Mode (default) – the wireless LAN adapter is constantly operating with full power. This mode consumes the most power.

• Maximum Power Save – the wireless LAN adapter consumes the least power.

This mode only operates when there is wireless network activity.

• Power Save – the wireless LAN adapter consumes moderate level of power.

Preamble: Select Long or Short Preamble type. Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach steady-state demodulation and synchronization of bit clock and frame start. Two different preambles and headers are defined: the mandatory supported Long Preamble and header, which interoperate with the 1 Mbit/s and 2 Mbit/s DSSS specification (as described in IEEE Std 802.11), and an optional Short Preamble and header (as described in IEEE Std 802.11b). At the receiver, the Preamble and header are processed to aid in demodulation and delivery of the PSDU. The Short Preamble and header may be used to minimize overhead and, thus, maximize the network data throughput. However, the Short Preamble is supported only from the IEEE

802.11b (High- Rate) standard and not from the original IEEE 802.11. That means that stations using Short-Preamble cannot communicate with stations implementing the original version of the protocol. Click “Apply” for the changes to take effect.

Support Band: There are two modes the user can select, including 11B and 11G.

The default setting is 11B and 11G are enabled, which is interoperable with both

11B and 11G devices.

Note: user must select one of 11B or 11G at least; otherwise the wireless connection will not function.

802.11g Wireless LAN Adapter.

Auth Mode: Select the authentication type from drop down list for Disable, Open

System, Shared Key, WPA, WPA-PSK, WPA2 and WPA2-PSK.

Open System / Shared Key

WEP Key 1~4: choose the encryption way, either in HEX or ASCII formats, and enter the password in the blank space.

18

Key Length: select 64 or 128 bits as the length of the keys. If you select 64bit in

Hex format, you must type 10 values in the following range (0~F, hexadecimal), or

64bit in ASCII format, you must type 5 values in the following range (0~9, A~Z and a~z Alphanumeric); If you select 128bit in Hex format, you must type 26 values (0~F, hexadecimal), or 128bit in ASCII format, you must type 13 values in the following range (0~9, A~Z and a~z Alphanumeric).
