Utility Configuration
Your ZyAIR 100 is Plug-and-Play and its default settings can be set for a typical infrastructure wireless
LAN. Simply install the ZyAIR 100 onto your computer and it is ready for use. In special circumstances
however, you may need to change configuration settings depending on how you want to manage your
wireless network. The ZyAIR 100 Utility enables you to make configuration changes and perform userlevel diagnostics.

Configure and monitor your ZyAIR 100 using the following utilities: Configuration, Loop Back, AP
Browser, Site Survey and About.
4.2.2 Configuration
The Configuration menu allows you to view and modify the current configurations of your ZyAIR 100
easily and quickly. The configuration settings include: ESS ID, SS ID, Network Type, Use WEP and
Transmission Rate. Within the Advanced setting, you can set Power Save, RTS or Frag Threshold, IRQ
and I/O address.
Parameter Configuration
4-3
ZyAIR 100 Wireleass PC Card
SS ID
The SSID is a unique ID given to the Access Point. Wireless clients associating to any Access Point must
have the same SSID. Select SSID and enter a specific SSID (Access Point) you desire to connect with.
Alternatively, you may not select the SSID (default setting). This allows your wireless adapter to
automatically associate to any Access Point in the vicinity of your wireless adapters. You can leave SSID
field blank, or enter ANY (all characters in uppercase). It is recommended that you select the SSID option.
This will prevent your computer from accidentally connecting to a different wireless network.
When moving your computer to another location within the network environment and it becomes out-ofrange of the current Access Point, the roaming function will automatically connect your computer to
another Access Point.
Network Type
To connect your wireless station to a local network infrastructure, set the station operation mode to
Infrastructure (with Access Point as default setting). In case you do not wish to connect to a network
infrastructure, but prefer to set up a small wireless workgroup, you can enable the Ad-hoc (without Access
Point). When the Ad-hoc mode is selected, be sure to set your wireless stations with the same channel.
ZyAIR 100 works with any IEEE 802.11 and 802.11(b)-compliant Access Points.
Transmission Rate
ZyAIR 100 provides various transmission (data) rate options for you to select. Transmission Rate options
include Fully Auto, Fixed 1 Mb/s, Fixed 2 Mb/s, Auto Select 1M or 2M, Fixed 5.5Mb/s and Fixed
11Mb/s. In most networking scenarios, you will see that the factory default Fully Auto will prove the most
efficient. This setting allows your ZyAIR 100 to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, ZyAIR 100 will automatically switch to a lower
transmission (data) rate. Transmission at lower data speeds are usually more reliable. However, when the
communication quality improves again, ZyAIR 100 will gradually increase the transmission (data) rate
again until it reaches the highest available transmission rate.
If you wish to balance speed versus reliability, you can select any of the above options. Fixed 11Mb/s or
Fixed 5.5Mb/s is used in a networking environment where you are certain that all wireless devices can
communicate at the highest transmission (data) rate. Fixed 1Mb/s, Fixed 2Mb/s, Auto Select 1M or 2M
are used often in networking environments where the range of the wireless connection is more important
than speed.
Use WEP (Wired Equivalent Privacy)
To prevent unauthorized wireless stations from accessing data transmitted over the network, ZyAIR 100
offers highly secure data encryption known as WEP. If you require high security in transmission, please
select Enable and click the WEP Key button.

Parameter Configuration
ZyAIR 100 Wireless PC Card
Figure 4-2 Utility – WEP Encryption
The Encryption dialog box enables you to identify four different encryption keys and select one of them to
encrypt your transmission data. There are two methods to set the WEP keys as describeds:
Create Encryption Keys by Using a Passphrase
To create encryption keys by using a passphrase, Select either the 64bit or 128bit encryption first and then
select Create Key with Passphrase and type a character string in the Create Key with Passphrase field.
As you type, the utility uses an algorithm to generate four keys automatically. Select one of the four WEP
keys and click OK. Then click the Apply button on the Configuration tab to make the setting take effect.
Create Encryption Keys Manually
You can also create up to four encryption keys manually by selecting Create Keys Manually.
For 64bit encryption you may choose:

To allow encrypted data communications, you must set the same encryption key
values on all wireless stations and/or Access Points. For example, if you use Key 1 on
your ZyAIR 100 and the value is (e.g., MyCar), the same value must be assigned to
Key 1 for all other client stations. The values you enter on the Encryption dialog box
will only be visible the first time you enter the keys. After closing this dialog box, all
Key values will be displayed as “xxxxxxxxxxxx” every time the tab is displayed again.

RTS Threshold
The RTS Threshold prevents the Hidden Node problem. Hidden Node is a situation in which two stations
are within range of the same Access Point, but are not within range of each other. The following figure
illustrates an example of the Hidden Node problem. Both stations (STA) are within range of the Access
Point, however, they cannot hear each other. Therefore, they are considered hidden nodes from each other.
When a station starts data transmission with the Access Point, it might not notice that the other station is
already using the wireless medium. When these two stations send data at the same time, they might collide
when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of
messages for both stations.
Figure 4-4 RTS Threshold
Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS
Threshold on a possible hidden station, this station and its Access Point will use a Request to Send/Clear
to Send protocol (RTS/CTS). The station will send an RTS to the Access Point, informing that it is going to
transmit the data. Upon receipt, the Access Point will respond with a CTS message to all stations within its
range to notify all other stations to defer transmission. It will also confirm with the requesting station that
the Access Point has reserved it for the time frame of the requested transmission.
Normally, the Disable option (default) is selected when you are not concerned with the Hidden Node
problem. When the Hidden Node problem becomes an issue, please select Enable and specify the packet
size. The RTS function will be activated if the packet size exceeds the value you set. It is highly
recommended that you set the value ranging from 0 to 2432.
Parameter Configuration
4-7
ZyAIR 100 Wireleass PC Card
Enabling the RTS Threshold causes redundant network overhead that could negatively
affect the throughput performance instead of providing a remedy.
Frag Threshold
Fragmentation improves the efficiency when high traffic flows along in the wireless network. If your
ZyAIR 100 often transmits large files in the wireless network, you can enable the Fragmentation
Threshold by clicking Enable in Advanced Configuration window and the function will split the packet.
The value can be set from 256 to 2432. Frag Threshold is set to Disable by default.
4.2.3 Loop Back
Figure 4-5 Utility – Loop Back
The Loop Back examines data transmission quality between your ZyAIR 100 and any computer on the
network. By entering IP address of two remote station, setting ping interval and packet size, you may
know whether communication has been made successfully or not. You may also run the loopback test by

Be sure to read and follow all warning notices and instructions.
Do not service the product by yourself. Refer all servicing to qualified service personnel.
Generally, when installed after the final configuration, the product must comply with the applicable
safety standards and regulatory requirements of the country in which it is installed. If necessary, consult
the appropriate regulatory agencies and inspection authorities to ensure compliance.
A rare condition can create a voltage potential between the earth grounds of two or more buildings. If
products installed in separate building are interconnected, the voltage potential can cause a hazardous
condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists
and if necessary, implement corrective action before interconnecting the products. If the equipment is
to be used with telecommunications circuit, take the following precautions:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet location unless the jack is specially designed for wet location.
• Never touch non-insulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines (other than a cordless telephone) during
an electrical storm. There is a remote risk of electric shock from lightning
In order to limit Radio Frequency (RF) exposure, the following rules should be applied:
• Install the antenna in a location where a distance of 20 cm from the antenna may be maintained.
• While installing the antenna in the location, please do not turn on the power of wireless card.
• While the device is working (transmitting or receiving), please do not touch or move the antenna.
• Do not operate a portable transmitter near unshielded blasting caps or in an explosive environment
unless it is a type especially qualified for such use.
For Laptop (notebook) computer users, in order to comply with the FCC RF exposure limits, it is
recommended when using a laptop with a wireless LAN adapter card that the card’s integrated antenna
should not be positioned closer than 5 cm (2 inches) from your body or nearby persons for extended
periods of time while it is transmitting (or operating). If the antenna is positioned less than 5 cm (2
inches) from the user, it is recommended that the user limit exposure time.
