2. Wireless LAN Basics
Wireless LAN (Local Area Networks) systems offer a great number of advantages over a traditional,
wired system. Wireless LANs (WLANs) are more flexible, easier to setup and manage and often more
cost effective than their wired equivalence.
Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the
need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through
simplified configuration, enable movable LANs.
With wireless LANs, users can access shared information without looking for a place to plug in and
network managers can set up or augment networks without installing or moving wires. Wireless LANs
offer the following productivity, convenience and cost advantages over traditional wired networks:
• Mobility - Wireless LAN systems can provide LAN users with access to real-time information
anywhere in their organization. This mobility supports productivity and service opportunities not
possible with wired networks.
• Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can
eliminate the need to pull cable through walls and ceilings.
• Installation Flexibility - Wireless technology allows the network to go where wires cannot go.
• Reduced Cost-of-Ownership - While the initial investment required for wireless LAN hardware
might be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle
costs will be significantly lower. Long-term cost benefits are greatest in dynamic environments
requiring frequent moves, adds, and changes.
• Scalability - Wireless LAN systems can be configured in a variety of topologies to meet the needs
of specific applications and installations. Configurations are easily changed and range from peer-
to-peer to full infrastructure networks, also allow roaming over a broad area.

and meanings of the various screen messages.
User’s Guide 18
4.1 Link Information
- Connected To Network
-
-
This field is used to display the current status of connection. When the state shows “Connected to
Network“ means normal flow of operation in Infrastructure mode. The PC is connected to access
point. Networking is available.
A state of “Scanning” means that the node is searching for available access point and detecting
the SSID for an available access point within range.
This field will also display an error message for some reason if the driver fails to initialize.
Network Type
Infrastructure Mode - The driver will scan all available channels continuously until it finds one or
more Access Points that match its SSID. At that point it will try and authenticate and
associate with the Access Point.
Peer to Peer Mode - The driver will scan for 5 seconds looking for an existing Ad Hoc network
using the same SSID.
- Current Channel and Transmit Rate
User’s Guide 19
Shows the channel of the radio and transmit rate being currently used for an active connection.
This value has no meaning when the radio is “Scanning”
- Link Quality
The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph
displays the quality of the link between the node and Access Point.
- Signal Strength
The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar
graph displays normalized signal strength as reported by the radio, averaged over all frames over
100 bytes long that are received from the Access Point.
User’s Guide 20
4.2 Availiable Networks
The Connections Tab shows current status of available APs within the network.
User may select profile or ESSID from above list, click “Connect” to connect with the AP.
Click “Refresh” to rescan the network, this utility with site survey function, it will detect and list all
available AP’s within network.

4.3 Profile Setting
Profile Setting allows user to create profiles for different network environments.
Click “Add” button to create new profiles.
“Edit” for editing current exist profile.
Click “Delete” button if you wish to delete profiles.
- Network Type
This field allows you to select from a list of supported Network “Modes”. The modes displayed will
have two values: “Peer to Peer” and “Access Point”.
Peer to Peer - This is the 802.11g peer-to-peer mode of operation. In 802.11g Ad Hoc, only one
wireless “cell” is supported for each different SSID. All communication is done from Client to Client
without the use of an Access Point. 802.11g Ad Hoc networking uses the same SSID for
establishing the wireless connection.
User’s Guide 22
Access Point - This mode of operation requires the presence of an 802.11g / 802.11b Access
Point. All communication is done via the Access Point, which relays packets to other wireless
Clients in the BSS as well as to nodes on a wired network such as Ethernet.
Transmit Rate – The transmission rate at which client of AP transmits the data packets. You may
set this to fixed 1Mbps, fixed 2 Mbps, fixed 5.5 Mbps, fixed 11 Mbps or Automatic for 802.11b’s
AP and fixed 6Mbps, fixed 9Mbps, fixed 12Mbps, fixed 18Mbps, fixed 24Mbps, fixed 36Mbps,
fixed 48Mbps, fixed 54Mbps or Automatic for 802.11g’s AP.
Encryption (WEP) - You may desire an additional measure of security on your wireless network,
which can be achieved by using WEP (Wired Equivalent Privacy) encryption and WPA pre-
shared key.
User’s Guide 23
When an encrypted frame is received it will only be accepted if it decrypts correctly. This will only
happen if the receiver has the WEP Key used by the transmitter.
This panel allows to entry for 64/128-bit encryption according to WEP function select. To be written
to the driver and registry, such as Hexadecimal format, each key must consist of hex digits, which
means that only digit 0-9 and letters A-F are valid entries. If entered incorrectly program will not
write keys to a driver.
WPA pre-shared key is one advanced security for wireless network. There are 2 types algorithm
could be supported – one is TKIP, and the other is AES.
To use WPA Pre-Shared Key, enter a password in the WPA Shared Key field between 8 and 63
characters long.
User’s Guide 24
To enable the used of IP Setting, please select enable.
The main purpose to make used of this function is to properly configure the TCP/IP setting of each
wireless connection.
Please define if the current Profile IP setting will be assign by a DHCP Server or just assign by a fixed
IP that is determinate by the Network Administrator.
When the DHCP Status is Enable, the TCP/IP information will be assigned by a DHCP Server. Or
otherwise please fill up with the correspondence data of the IP settings.

5. Troubleshooting
If you encounter any problems during the installation, or to confirm that the WLAN 11Mbps
device is installed properly, please read the following troubleshooting section.
In Windows 98:
To check that the WLAN 802.11g device is installed properly, please do the following:
1. Go to START>SETTINGS>CONTROL PANEL>NETWORK. Choose the Configuration Tab.
If you find the WLAN 802.11g Adapter, it means the card is installed properly. If you see the
Yellow Question-mark (?) means the resources are conflicting. (Please read further in this
section for solutions.) -or-
2. Right click on My Computer and select Properties. Select the Device Manager and click on
the Network Adapter. You will find the WLAN 802.11g Adapter if it is installed successfully. If
you see the Yellow sign, the resources are conflicting. Click on the PCMCIA Card and then on
the PCMCIA Card Service, you can see the status of the PC card. If there is a yellow sign either
on the adapter or the PC card, please check the following.
1. Check to see if your computer has a free IRQ. If not, make an IRQ free by assigning
the same IRQ to some devices, for example COM 1; COM 2 can be assigned the
same IRQ values.
2. Check that you have inserted the right card and have installed the proper driver.
In Windows 2000:
1. Check the Windows 2000 Diagnostics. See if there is any conflict in the resource
allocation or the I/O Address, IRQ allocations. If you find that the IRQ or I/O Addresses
are already assigned to some other devices, you must change that value. I/O Address
needs 40h byte length.
2. Go to the Control panel. Double click on the PCMCIA Card and you will see WLAN
Adapter. Double clicking on that will show you the Card Information, driver name and the
driver file. If you do not find the names, there are some problems and the driver is not
installed properly. Reinstall the driver.
Note: Check the PnP BIOS setup menu and select no in case of the WLAN Adapter
installation.
