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.

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.
20
• 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.
21
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.
23
• You should consult your network administrator or Internet Service Provider (ISP) to find out if you would
use DHCP or static IP.
• Windows Internet Name Service (WINS) is a network service that resolves a computer NETBIOS name
to an IP address. It is similar in concept to the Domain Name Service (DNS) except WINS resolves
NETBIOS names while DNS resolves host names.
• If you use a static IP and want to enable WINS, You should consult your network administrator or Internet
Service 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, it
can also be called a specific point to access another system. So if you want to reach out to Internet from your
PC, you should set up a gateway to pass through.
• You should consult your network administrator or Internet Service Provider (ISP) to find out your
Gateway Address.
• Domain Name Service (DNS) is the service that performs a mapping between domain names – more
English-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 network
administrator or Internet Service Provider (ISP) to find out your Host ID, Domain, DNS Server IP
Address, 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 ready
with all the information necessary to proceed more.)
24
3.5.3 Setting Network Properties for “StructureNet” mode
1. 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.

uses channel 1, the adjacent AP should use channel 6 or higher for the best output.
Default: 1
RTS_threshold: This field determines the size of RTS(Request-To-Send)/CTS(Clear-To-Send) frames and
the frames to be used.
Default: 2301
short_retry: This field specifies the number of transmissions of RTS/CTS to be attempted before aborting
when the communication between clients is interfered. Note that RTS/CTS are delivered back and forth
between the clients to monitor the channel for the possibility of communications.
Default: 15
long_retry: This field specifies the number of trials of data transmission when the channel or a client causes
the cease of data transmissions.
Default: 15
Standard: This field is used for interoperability between multiple IEEE 802.11 venders.
Default: on

Field Name
Description
Station ID
This is the NID (Network ID) or the name of the station if
set. The name is obtained from the NID name table.
IP Address
The IP address of the station ( if known )
“Associated” means that the station is associated with this
Access Point.
“Disconnected” means that the station is not associated
with this AP could however, be associated with another AP.
“Detected” means that frames from the station have been
Status
seen but, that it has not been associated.
“Bridged” entries are wired stations that are reached
through a different Access Point than the current displayed
one.
“Is Bridging” is Access Points detected over the air. These
other Access Points provide for wireless bridging between
two separate LAN segments.
“Local AP” means that it is another AP on the same LAN.
This entry will be seen where roaming is implemented.
Channel
The radio channel of the station.
AP Serving
If the station is associated the words “This Unit” will
appear.
Otherwise the NID or name of the Access Point to which
the station is associated will be shown.
Power Mode
If the station supports “Power Save Poll” mode of
IEEE802.11, this field will indicate that power saving is
active with the word “On”.

7.4.2.3 Explanation on various Commands
• help:
Displays list of all the commands.
Usage: help [command]
• show:
Displays the number of attached clients in both wireless and wired LAN.
Similar to the “Bridge Table Report” screen of the Web Management Utility.
a. Usage: show [A | G | S]
- A: List of all known clients attached via wireless LAN.
- G: List of all known clients attached via wired LAN.
- S: List of all wireless stations.
b. The result of the command is list providing the following information.
- Net ID: IEEE network address of the client.
- State: Current relationship of client with AP
(Associated, Disconnected, Detected, is bridging, bridged, Local AP, Unknown).
- Channel: Radio channel.
- Power: Whether the power of the client is on or off. (On, Off)
- Current AP: The Access Point with which the unit is associated.
- IP address: IP address of the client.
• time:
Displays the current date and time and those of last restarted time.
• settime: Sets the system time.
Usage: “settime HH(hours):MM(minutes):SS(seconds)”
• setdate: Sets the system date.
Usage: “setdate MM(month):DD(date):YY(year)”
• config: Displays the current system settings for configuration. Note that if a configuration
change has been made which requires a system restart to take effect, both the old and the new
values will be shown.
• stats:
Displays traffic statistics. Statistics are displayed for the last 10
second interval. To
view the cumulative total, use the command line of “stats c”.
• logout: After this command has been issued the user must re-enter the password before any
more commands can be issued.
• ver:
Displays version information about the Access Point software.
• restart: Reinitializes the SWL-2000AP.
• ping:
Issues an ICMP Echo request (PING) to the specified IP address.
Usage: “ping xxx.xxx.xxx.xxx [yy]”
(Here, “xxx.xxx.xxx.xxx” is the destination IP address and yy option will make this ping
command executed indefinitely.)
• nid:
nid is the unique number of wireless LAN card, which is also called “MAC Address”.
Usage: “nid [add | delete] 123456789abc NAME” / “nid list”
72
(Here, “123456789abc” is the new NID value and “NAME” is a text string up to 9
characters with no space in between.)
• trace:
Displays the contents of the trace buffer. This command does NOT clear the trace
buffer so that issuing the command twice will produce the same result.
• traceclr: Clears the entries which have been read by the trace command.
• tracelp: Displays a continuously updated log to the screen. To exit, press .
Usage: “tracelp”
: Updates the display every 5 seconds.
“tracelp Q”
: Updates the display every second.
“tracelp S”
: Updates the display every minute.
• traceon: Activates tracing for certain events. (Refer to “traceoff”)
• traceoff: Deactivates tracing for certain events.
Usage: “traceoff  ”
Here, specifier is of the following strings:
- “br+” : Traces new entries in the bridge table.
- “br-”
: Traces bridge table entries which age out.
- “IP+” : Traces new TCP/IP address.
- “sys”
: Traces authenticate, associate, WIN/LOSE negotiations (roaming).
- “all”
: Turns off or on tracing of all events.
Default specifier Combinations are like the following:
- “traceon sys”
- “traceoff br+ br- IP+”

8.3 Brief Troubleshooting
If you encounter some problems while installation, please try one or more of the followings.
• Check the driver configuration if the driver you are using is the correct one for your networking
environment.
• Reboot with the Adapter inserted.
• Completely remove and reinstall the Adapter and driver.
• A common problem is a driver/firmware version mismatch. If the driver fails to find the card, this is often
the case. Inform this to your retailer and try to install with different combination of driver and firmware.
• Check the resources used by the card to make sure no resource is being used by another device in your
system.
(To see your resources setup, right click on My Computer icon, click on Properties, go to Device Manager
tab, and click on Properties. The windows will display I/O Address, IRQ, DMA Channel and Memory
ranges occupied on your system.)
