Terminology Used in this Guide
Ad Hoc Network
An ad hoc network is formed by a number of wireless stations (without an access point) communicating via radio waves. For the users, the shared resources on the wireless network appear exactly as they would on a regular wired network. The wireless operation of the network is totally transparent. Figure 1 depicts a typical ad hoc network scenario.

Computers
Figure 1. An Ad Hoc Network
Infrastructure Network
An infrastructure network is formed by several stations and one access point (AP), with the stations within range of the AP. Figure 2 depicts a typical infrastructure network topology.

BSSID/MAC ID
BSSID (Basic Service Set ID) is an ID unique to each AP that is factory set and is identical to the MAC ID (Media Access Control ID). It allows each AP to be identified on the network.
Domain Name
/
SSID
A domain is usually defined by the network administrator as a segment/subnet of a large network and may be made up of overlapping wireless cells. Wireless nodes can roam freely within the same domain without disconnecting from the network.
Figure 3 depicts a common wireless network setup.

Configuration
Configuration ( Figure 16 ) displays, and allows you to modify, some important
parameters of the InstantWave adapter. All parameter changes are saved and are
referred to by the InstantWave driver when the system boots.
•
Network Mode – The IEEE 802.11 and IEEE 802.11b wireless specifications allow for two types of network, infrastructure and ad hoc . Infrastructure is used when networking with an access point. The default setting is
Infrastructure .
•
Domain Name (SSID) – Stations and APs in the same group must use the same domain name. This name is defined in the 802.11b wireless standard as the SSID (Service Set ID).
Having the same domain name allows all wireless nodes in the same domain
(or cell) to communicate with each other. The default setting is TIWLAN . All
SSIDs entered will be stored and may be accessed from the dropdown list.
You can clear the list by clicking Empty SSID .
Note: The SSID is case-sensitive and should not contain any spaces.
•
Empty SSID – Clears the SSID list.
•
Transmission Rate – The speed at which the data packets are transmitted by the client or AP. You can set this to 1Mb (that is, 1 megabit per second), 2Mb ,
5.5Mb
, 11Mb, 22 Mb, or Fully Automatic . Usually this should be set to Fully
Automatic . In an electromagnetically “noisy” environment, a lower rate can provide more stable transmission quality.
•
Channel – For ad hoc networks only. In a multiple cell network topology, overlapping and/or adjacent cells using different channels can operate simultaneously without interference if the frequency distance between the center frequencies is at least 30 MHz. For example, channels 1, 7, and 13 are non-overlapping channels.
In the case of an infrastructure network, changing the channel number has no affect as the channel is scanned for automatically. The client will look for an
AP with the same SSID, and automatically associate with it.
•
Power Saving Mode – Power saving mode is used to minimize the power consumption of the adapter when the notebook PC is powered by battery. Be aware that the transmission performance will be degraded when power saving is enabled.
18 CardBus Enhanced Wireless Network Adapter

CardBus Enhanced Wireless Network Adapter 19
Link Info
Click the Link Info tab to view wireless connection properties ( Figure 18 ).
Figure 18. Adapter Properties/Link Info
•
State – State shows whether the client is connected to an AP or not. If connected, it also shows the BSSID (Basic Service Set ID) address of the AP.
This is also the AP’s MAC address.
•
Current Channel – Channel number is the channel used for communication between the clients and AP or between the clients only. In infrastructure network mode, the associating stations will scan for the channel the AP is
20 CardBus Enhanced Wireless Network Adapter
using and change to the same channel automatically. In ad hoc network node, the channel number must be set manually on each client that wishes to connect.
•
Current Tx Rate – Shows the current wireless transmission rate.
•
Signal Strength – Displays the signal strength level.
•
Rescan – Clicking Rescan forces the client to rescan for an access point with the same domain name on a different channel.
Encryption
Data encryption provides more secure wireless data communication. Click the
Encryption tab to setup/change the security settings ( Figure 19 ). The default is
Disabled
and initially the keys section will be blank.
CardBus Enhanced Wireless Network Adapter 21
Figure 19. Adapter Properties/Encryption
•
WEP – WEP stands for Wired Equivalent Privacy and is an encryption scheme that provides secure wireless data communications. WEP uses a 40-, 128-, or
256-bit key to control network access. In order to decode transmissions, each wireless client on the network must use exactly the same key.
Disabled (default): Stations and APs communicate without any data encryption.
40-bit WEP : Stations and APs communicate using 40-bit WEP encryption.
128-bit WEP : Stations and APs communicate using 128-bit WEP encryption.
256-bit WEP : Stations and APs communicate using 256-bit WEP encryption.
Note that not all wireless devices support 256-bit encryption.
22 CardBus Enhanced Wireless Network Adapter
•
WEP Key Generation – There are two ways to create a WEP key:
The first is by entering text in the Passphrase field and then clicking Generate .
For 40-bit WEP, four WEP keys will be generated – Key 1, Key 2, Key 3, and
Key 4. You must select the key currently being used on the network. If you do not select a key, Key 1 will be selected. For 128- and 256-bit WEP, a single key will be generated.
The second way to create a WEP key is by inserting the key values directly from the keyboard. If the key is not entered correctly, a client cannot access the resources. If WEP is enabled on the AP, all clients must use the same WEP key to connect to it.
CardBus Enhanced Wireless Network Adapter 23
Troubleshooting
Should a problem be encountered that cannot be resolved using the
‘Troubleshooting’ section of this manual, click the Troubleshooting tab ( Figure
20 ).
Figure 20. Troubleshooting
A diagnosis program will run and display a diagnostic message. Follow the onscreen instructions to send the message, together with a description of the symptoms, to NDC’s technical support via e-mail.
24 CardBus Enhanced Wireless Network Adapter
Site Survey (Infrastructure Mode Only)
Site Survey scans for all existing APs and displays the domain name (SSID),
BSSID (MAC ID), channel number, signal strength, network mode, WEP status, and estimated distance. It also gives users the option of selecting a particular access point to associate with (and thus “join” a wireless network).
When Site Survey is run, the program first reads and displays information stored in the database. The information is not dynamically updated. To refresh the data click the Scan button.
The Signal Strength column shows either green (strong signal), or yellow (average signal).
Figure 21. Site Survey
Scan
Click Scan to obtain and display updated BSSID information. You may need to wait a short time until the scan is completed.
Join
Selecting one of the APs from the list will enable the Join button. The Join command allows you to manually connect to a specific AP. Alternatively, you can double-click the AP’s entry in the list.
If joining cannot be accomplished within 20 seconds (possibly due to an AP that has gone off the air since the data was last refreshed, RF interference, or a busy
AP), the operation will fail. If this happens, you may try joining with the same AP again, or select another AP to join.
CardBus Enhanced Wireless Network Adapter 25
Signal Quality Indicator
Signal Quality Indicator dynamically displays the current radio signal quality
( Figure 22 ). The quality level is indicated by colors. Green means the signal is
good, yellow indicates the signal is fair, red denotes the signal is poor. When the
signal quality goes from fair to poor, the station will search for a different AP.
