1. MagicLAN Introduction

1.1 Introduction

Thank you for your purchase of SAMSUNG MagicLAN (SWL-2000N) Wireless LAN Adapter.. Installing card allows the computer to join a wireless network based on the IEEE 802.11 wireless LAN standard. You will be surprised how easy for you to be a part of network with no bother of twisted cables.

1.2 Technical Background

• What is IEEE 802.11? The IEEE 802.11 specification is a wireless LAN standard developed by the IEEE (Institute of Electrical and Electronic Engineering) committee in order to specify an “over an air” interface between a wireless client and a base station or Access Point, as well as among wireless clients. Like other IEEE 802 families, IEEE 802.11 specification addresses both Physical (PHY) layer and Media Access Control (MAC) layer.

• IEEE 802.11 Physical (PHY) Layer At the PHY layer, IEEE 802.11 defines three physical characteristics for LAN: diffused infrared, Direct Sequence Spread Spectrum (DSSS), and Frequency Hopping Spread Spectrum (FHSS). While the infrared PHY operates at the baseband, the other two PHYs operate at the 2.4GHz ISM (Industrial, Scientific, and Medical) band, which can be used for operating wireless LAN devices without the need for end-user licenses. In order for wireless devices to be interoperable, they have to be conform to the same PHY standard.

• IEEE 802.11 Media Access Control (MAC) Layer The IEEE 802.11 MAC Layer is mainly concerned with rules for accessing the wireless medium. There are two network architectures defined: StructureNet Network and Peer-to-Peer Network.

• Peer-to-Peer Network Peer-to-Peer Network is an architecture that is used to support mutual communication among wireless clients only. Since Peer-to-Peer Network does not support access to wired networks, it does not need an Access Point to be a part of the network. You can use the network immediately after setting up the operating mode using the supplied network driver.

• StructureNet Network StructureNet Network is architecture to provide communication between wireless clients and wired network resources. The transition of data is defined by an Access Point (AP) and the associated wireless clients. So a wireless client can access all the services that are available for a regular wired LAN by using Access Point (AP).

• Instawave Network Instawave Network is architecture to provide both Peer-to-Peer Network features and StructureNet Network feathers at the same time. In other words, wireless clients on the network can directly communicate with each other while they can also access wired LAN clients through AP if they want. Instawave Network is a good choice for small networks that need maximum flexibility and simplicity.

• Roaming Roaming is a service that allows wireless clients to use the network in motion by automatically moving the connection to an old Access Point into a new Access Point when the clients enter into a new cell.

• Scanning, Beaconing & ESS ID When a wireless client is initialized, it is necessary for it to find and communicate with the correct group for wireless devices, including Access Point (AP). At this point, it may search for all the frequency channels and this process is called “scanning.” There may be multiple APs and network operating at the same time. It may be necessary to ensure that the station joins with the correct network during the scanning process. To achieve this, each AP is assigned to be part of a logical group called the Extended Service Set (ESS). The name of this logical group is the ESS ID. When roaming is operating, there may be several Access Points as part of the same ESS. After powering up, the wireless client will listen on its default frequency channel. It will be listening for “beacons” sent by another wireless station or AP. Here, a beacon is a short message containing the ESS ID that will be broadcast roughly ten times a second. When the wireless station hears a beacon, if the ESS ID in the beacon matches its own, the client knows that it is on the correct channel and can communicate with its group. If no beacons are seen, or if the ESS ID does not match, the wireless client may move to the next frequency channel and repeat this listening procedure. If all frequency channels have been searched with no matched ESS ID found, it will assume that it is the first client in the group to wake up and will return to its default channel and start to issue beacons itself. In DSSS, this scanning process occurs at start up and may also occur when the client roams between APs.

1.3 MagicLAN Overview

• The SWL-2000N (for Notebook) is a wireless LAN adapter card that provides wireless connection between PCs.

• The MagicLAN is designed to operate with IEEE 802.11 (wireless LAN International Standard) wireless compliant radio cards and uses a CSMA/CA (Collision Sense Multiple Access with Collision Avoidance) algorithm as the media access scheme, which makes high speed communication with minimal collision possible.

• The MagicLAN supports DSSS (Direct Sequence Spread Spectrum). This is a radio technique, which scrambles the data prior to transmission and uses a correlation technique on receiving to improve the signal to noise ratio and makes it possible to communicate in the office having a wall and a compartment.

• The function of the MagicLAN SWL-2000AP (Access Point) is to transfer information from a wired LAN to a wireless LAN and vice versa. When operating, the MagicLAN AP is invisible to most users (Normally, unless the user is an administrator, the MagicLAN AP cannot be seen or accessed by users on the network).

• The SWL-2000N for Notebook PC is small and portable as a roaming function is provided for users who need network services while maintaining mobility.

• The MagicLAN Adapter has three LED’s (Light Emitting Diodes) on the part of the card: Power, Tx, and Rx. The red Power LED will illuminate when the power is applied. The orange Tx LED and green Rx LED will illuminate when the date is transmitted out and in respectively.

• The MagicLAN supports various network software. The network driver is provided to support most network software such as MS-DOS Packet, Windows 95/98, and Windows NT 3.51/4.0.

2. Before the Installation

The following section will assist you in successfully installing your wireless network adapter card. You will first install the hardware and software, then set network properties to accommodate resource sharing and to select the type of wireless network you wish to install.

3.4 MagicLAN Wireless LAN Card Properties Setup

3.4.1 Before MagicLAN Wireless LAN Card Properties Setup

3.4.1.1 Basics regarding the Properties Setup

• Peer-to-Peer Operating Mode: Multiple wireless clients can directly communicate with each other without AP.

• StructureNet Operating Mode: Wireless clients can communicate with each other or with clients on another wired network always through AP.

• Instawave Operating Mode: Multiple wireless clients using the same channel can directly communicate with each other, And they also can communicate with clients on another wired network through AP. In the second case, it is automatically set up which AP will be used for it.

• Roaming: One feature of StructureNet operating mode that effortlessly moves between APs that are on different channels but have the same ESS ID.

• From your network administrator, you should find out ESS ID of the AP and channel number that you are supposed to use.

3.4.1.2 Meanings of the Properties Setup Options

• Default Scanning / Start Channel: Option in StructureNet and Peer-to-Peer Network) StructureNet operating mode enables clients to automatically search for new Access Point. In Default Scanning mode, the wireless client begins the search with Channel 1. The client then searches all consecutive channels until it finds a new AP with the same ESS ID. If you want to start the search from a specific channel other than channel 1, you can deselect the Default Scanning check box and enter the desired channel number in a blank for Start Channel. This Start Channel entry will be helpful when multiple APs are within range of each other and you desire to connect to a specific AP among them.

• Enable Power Saving: Option in StructureNet Network Power save mode will keep the wireless LAN adapter in a low power standby state when there is no data transfer. This Enable Power Saving option is mainly to extend the operating time of portable battery operated device such as laptop computers, even sacrificing the effective throughput of the wireless connection. So you should test both with and without power saving enabled to see if this option satisfies your needs.

• Case sensitive ESS ID: Option in StructureNet and Peer-to-Peer Network When entering ESS ID, you can make it case sensitive by checking Case sensitive ESS ID check box.

• Auto join: Option in StructureNet and Peer-to-Peer Network When Auto join option is selected, the wireless client will associate with whatever access point is within range and has the best signal independent of the ESS ID setting. Since you may not use the same AP as described in the “Access Point Client Properties” box, you can check which AP and ESS ID you are actually using by double clicking the task bar status icon to display the wireless client status box.

3.4.2 Setting Network Properties for “Peer-to-Peer” mode

1. Right click on your “Network Neighborhood” icon and click on “Properties”.

2. “Network” box will appear with Configuration tab selected as follows. In the list in the box, click on “SAMSUNG Wireless LAN Card” and “Properties” button in the middle sequentially.

3. “Access Point Client Properties” box will appear as follow.

4. Check the Peer-to-Peer radio button in Operating Mode list.

5. Enter the desired ESS ID you are authorized to use. (ESS ID is set to “MagicLAN” as default, but you can change it to another.)

6. Select the desired Channel you are authorized to use.

7. Change some options if you want.

8. Click on “OK” to finish up the setup.

9. “System Setting Change” box will appear as follows. Click on “No” to proceed to Network Configuration Setup before you restart your computer.

3.5 Network Configuration Setup

3.5.1 Network Configuration Setup Overview

• After you finish up the hardware and software driver setup, you will need to install and configure Microsoft Networking components.

• If you only need to access the Internet, installation of the TCP/IP networking component should be sufficient.

• If you want some functions to share files and printers in small LAN environment, some installations may use an alternative networking protocol called NetBEUI protocol.

• Both TCP/IP and NetBEUI protocols can be used to share files and printers between wired and wireless computers.

3.5.2 Before TCP/IP Networking Configuration Setup

3.5.2.1 What you should know before Configuration

• TCP/IP protocol is a protocol used to connect to a Wide Area Network (WAN), such as the Internet or hard-wired Ethernet networks.

• Every computer connecting to WAN has a unique number called IP address, which consists of two parts, network part and host part. For example, consider the IP address 150.205.30.9. Assuming this is part of a Class B network, the first two numbers (150.205) represent the network address and the second two numbers (30.9) represent the host address.

• Network administrator can divide the host part of IP address into two or more subnets for more effective use. In that case, subnet mask is used to determine what kind of subnet the IP address belongs to.

• You should consult your network administrator or Internet Service Provider (ISP) to find out your IP address and subnet mask.

• There are two ways of obtaining an IP address. Some networks use Dynamic Host Configuration Protocol (DHCP) to dynamically assign an IP address every time you log on to the network. Others use

static IP that is uniquely assigned to your computer and you use the same IP address whenever you log on to the network.
