71. MagicLAN Introduction1.1 IntroductionThank you for your purchase of SAMSUNG MagicLAN (SWL-2000N) Wireless LAN Adapter.. Installingcard allows the computer to join a wireless network based on the IEEE 802.11 wireless LAN standard. Youwill 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 andElectronic Engineering) committee in order to specify an “over an air” interface between a wireless clientand 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 MediaAccess Control (MAC) layer.• IEEE 802.11 Physical (PHY) LayerAt the PHY layer, IEEE 802.11 defines three physical characteristics for LAN: diffused infrared, DirectSequence Spread Spectrum (DSSS), and Frequency Hopping Spread Spectrum (FHSS). While the infraredPHY operates at the baseband, the other two PHYs operate at the 2.4GHz ISM (Industrial, Scientific, andMedical) band, which can be used for operating wireless LAN devices without the need for end-userlicenses. In order for wireless devices to be interoperable, they have to be conform to the same PHYstandard.• IEEE 802.11 Media Access Control (MAC) LayerThe IEEE 802.11 MAC Layer is mainly concerned with rules for accessing the wireless medium. There aretwo network architectures defined: StructureNet Network and Peer-to-Peer Network.
8• Peer-to-Peer NetworkPeer-to-Peer Network is an architecture that is used to support mutual communication among wirelessclients only. Since Peer-to-Peer Network does not support access to wired networks, it does not need anAccess Point to be a part of the network. You can use the network immediately after setting up the operatingmode using the supplied network driver.• StructureNet NetworkStructureNet Network is architecture to provide communication between wireless clients and wired networkresources. The transition of data is defined by an Access Point (AP) and the associated wireless clients. So awireless client can access all the services that are available for a regular wired LAN by using Access Point(AP).• Instawave NetworkInstawave Network is architecture to provide both Peer-to-Peer Network features and StructureNet Networkfeathers at the same time. In other words, wireless clients on the network can directly communicate witheach other while they can also access wired LAN clients through AP if they want. Instawave Network is agood choice for small networks that need maximum flexibility and simplicity.
9• RoamingRoaming is a service that allows wireless clients to use the network in motion by automatically moving theconnection to an old Access Point into a new Access Point when the clients enter into a new cell.• Scanning, Beaconing & ESS IDWhen a wireless client is initialized, it is necessary for it to find and communicate with the correct group forwireless devices, including Access Point (AP). At this point, it may search for all the frequency channels andthis process is called “scanning.”There may be multiple APs and network operating at the same time. It may be necessary to ensure that thestation joins with the correct network during the scanning process. To achieve this, each AP is assigned tobe part of a logical group called the Extended Service Set (ESS). The name of this logical group is the ESSID. 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 IDthat 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 thatit is on the correct channel and can communicate with its group. If no beacons are seen, or if the ESS IDdoes not match, the wireless client may move to the next frequency channel and repeat this listeningprocedure. If all frequency channels have been searched with no matched ESS ID found, it will assume thatit is the first client in the group to wake up and will return to its default channel and start to issue beaconsitself.In DSSS, this scanning process occurs at start up and may also occur when the client roams between APs.
101.3 MagicLAN Overview• The SWL-2000N (for Notebook) is a wireless LAN adapter card that provides wireless connection betweenPCs.• The MagicLAN is designed to operate with IEEE 802.11 (wireless LAN International Standard) wirelesscompliant 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 collisionpossible.• The MagicLAN supports DSSS (Direct Sequence Spread Spectrum). This is a radio technique, whichscrambles the data prior to transmission and uses a correlation technique on receiving to improve the signalto 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 LANto 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 whoneed network services while maintaining mobility.• The MagicLAN Adapter has three LED’s (Light Emitting Diodes) on the part of the card: Power, Tx, andRx. The red Power LED will illuminate when the power is applied. The orange Tx LED and green Rx LEDwill illuminate when the date is transmitted out and in respectively.• The MagicLAN supports various network software. The network driver is provided to support mostnetwork software such as MS-DOS Packet, Windows 95/98, and Windows NT 3.51/4.0.

203.4 MagicLAN Wireless LAN Card Properties Setup3.4.1 Before MagicLAN Wireless LAN Card Properties Setup3.4.1.1 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.
21• 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” mode1. 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.

(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.
233.5 Network Configuration Setup3.5.1 Network Configuration Setup Overview• After you finish up the hardware and software driver setup, you will need to install and configureMicrosoft Networking components.• If you only need to access the Internet, installation of the TCP/IP networking component should besufficient.• If you want some functions to share files and printers in small LAN environment, some installations mayuse an alternative networking protocol called NetBEUI protocol.• Both TCP/IP and NetBEUI protocols can be used to share files and printers between wired and wirelesscomputers.3.5.2 Before TCP/IP Networking Configuration Setup3.5.2.1 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 orhard-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 addressand 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 effectiveuse. 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 IPaddress and subnet mask.• There are two ways of obtaining an IP address. Some networks use Dynamic Host ConfigurationProtocol (DHCP) to dynamically assign an IP address every time you log on to the network. Others usestatic IP that is uniquely assigned to your computer and you use the same IP address whenever you log on tothe network.
24• You should consult your network administrator or Internet Service Provider (ISP) to find out if you woulduse DHCP or static IP.• Windows Internet Name Service (WINS) is a network service that resolves a computer NETBIOS nameto an IP address. It is similar in concept to the Domain Name Service (DNS) except WINS resolvesNETBIOS names while DNS resolves host names.• If you use a static IP and want to enable WINS, You should consult your network administrator or InternetService Provider (ISP) to find out the WINS server IP Address and Scope ID.• Gateway is a hardware or software set-up that translates between two dissimilar protocols. More easily, itcan also be called a specific point to access another system. So if you want to reach out to Internet from yourPC, you should set up a gateway to pass through.• You should consult your network administrator or Internet Service Provider (ISP) to find out yourGateway Address.• Domain Name Service (DNS) is the service that performs a mapping between domain names – moreEnglish-like names - and their corresponding IP address.• DNS can be either enabled or disabled. If you want to enable it, you should also consult your networkadministrator or Internet Service Provider (ISP) to find out your Host ID, Domain, DNS Server IPAddress, and Domain suffix.3.5.2.2 What you should have in your hands to proceed further• Whether you would use DHCP or static IP (Required)• Your Gateway Address (Required)• Your IP address and subnet mask. (If you want to use static IP)• WINS server IP Address and Scope ID (If you want to enable WINS using static IP)• Your Host ID, Domain, DNS Server IP Address, and Domain suffix   (If you want to use DNS)(Consult your network administrator or ISP if you are not sure any of the above, and make sure you are readywith all the information necessary to proceed more.)
253.5.3 Setting Network Properties for “StructureNet” mode1. Do the step 1 and 2 mentioned in the previous section. (Section 3.4.2)2. In “Access Point Client Properties” box, check the StructureNet radio button in    Operating Mode list.3. Enter the desired ESS ID for the Access Point you are authorized to use.    (ESS ID is set to “magicwave” as default, but you can change it to another.)4. Change some options if you want.5. Click on “OK” to finish up the setup.6. Do the step 9 mentioned in the previous section (Section 3.4.2) to make the change effective.
263.5.4. Setting Network Properties for “Instawave” mode1. Do the step 1 and 2 mentioned in the section 3.4.2.2.
