22 ZoomAir USB Client Installation Guide & Reference Manual
Network—The Network Type dropdown list tells you what type
of network the USB client is connected to: Infrastructure or
AdHoc. (For additional explanation of these network types, turn
to page 33.)
• The default is Infrastructure—this mode uses an Access Point
or Gateway to access a company network or the Internet.
Note:
If there are two Access Points with the same ESS ID,
check the BSS ID box and enter the MAC address of the
Access Point you want to connect to. Then type the ESS
ID in the accompanying field.
• The AdHoc mode allows you to set up a group of wireless
clients for file and printer sharing without using an Access
Point or a Gateway.
If you select AdHoc, be sure that all the wireless clients are set to
the same Current Channel and the same ESS ID. If you don’t
want to use the default ESS ID of any, check the ESS ID
checkbox to indicate that you want to specify it yourself, then type
the ESS ID in the field next to it. The software will attempt to
associate with all Access Points or clients with the same ESS ID.
The ESS ID is case-sensitive and can be a maximum of 32
characters.
Profile—The Profile field allows you to define profiles and set
values for all necessary parameters. Subsequently, you can select
from the dropdown list of defined Profiles.
To create a profile, go to the Profile field, type a profile name and
set the corresponding parameters. After specifying the profile
parameters that you want, save the profile by clicking Apply. You
can have multiple profiles and modify profiles at any time. If you
Chapter 4 Advanced Features 23
no longer want to use a profile, you can remove it by clicking the
Delete button.
Tip:
You can also select a profile by right-clicking the WLAN icon
in the system tray.
Transmit Rate—The USB Client provides several data rate
options, including Fully Auto, 2 Mb, Auto 1 or 2 Mb, 5.5 Mb,
and 11 Mb.
For most networks, the factory default Fully Auto will prove the
most efficient. This setting allows the USB Client to adjust and
operate at the maximum possible data rate. When the
communication quality drops below a certain level, the Client
automatically switches to a lower data rate (transmissions at lower
data speeds are usually more reliable). When the communications
quality improves again, the unit gradually increases the data rate
until it has achieved the highest available transmit rate.
WEP—Wireless Equivalent Privacy is meant to prevent
unauthorized wireless clients from accessing data transmitted over
the network.
To activate WEP, check the WEP Enabled check box that
appears under the Profile field.
An Encryption dialog box displays.
24 ZoomAir USB Client Installation Guide & Reference Manual
• Pull down the Encryption (WEP) menu and select either 64
bit or 128 bit.
• Specify the encryption keys. There are two methods to set the
WEP keys, as described below:
To Create Encryption Keys Using a Passphrase:
Follow these steps.
Click the Create Key with Passphrase check box and type a
1
character string of your choice in the Passphrase field. As you
type, the utility uses an algorithm to generate one key (in the
case of 128-bit) or four keys (in the case of 64-bit)
automatically. (Remember, you have already selected either 64
bit or 128 bit.)
Select one key out of the four and click OK. Note: With 64-bit,
2
the first key is the default and is usually fine.
Navigate back to the Configuration tab and click the Apply
3
button and then OK to have the setting take effect.
To Create Encryption Keys Manually
If you have selected 64-bit encryption, follow these steps.
Click the Create Key with Manual check box.
1
You have a choice of selecting an Alphanumeric or a
2
Hexadecimal scheme.
• Alphanumeric: 5 case-sensitive characters ranging from
“a-z”, “A-Z”, and “0-9” (for ex., MyKey)
• Hexadecimal: 10 hexadecimal digits in the range of “A-
F”, “a-f”, and “0-9” (for ex., 11AA22BB33).
Enter your WEP key of choice in the key field, select one key
3
as the active key, and click OK.
Navigate back to the Configuration tab and click the Apply
4
button and OK to have the setting take effect.
If you have selected 128-bit encryption, follow these steps.
Chapter 4 Advanced Features 25
Click the Create Key with Manual check box.
1
You have a choice of selecting an Alphanumeric or a
2
Hexadecimal scheme.
• Alphanumeric: 13 case-sensitive characters ranging from
“a-z”, “A-Z”, and “0-9” (for ex., MyKey12345678)
• Hexadecimal: 26 hexadecimal digits in the range of “A-
F”, “a-f”, and “0-9” (for ex.,
00112233445566778899AABBCC).
Navigate back to the Configuration tab and click the Apply
3
button and OK to have the setting take effect.
Note:
The WEP key must be set up exactly the same on any
wireless LAN stations and Access Points. For example, if
you set “MyKey” for a wireless LAN Card, the same
“MyKey” must be assigned to the Access Point or other
stations.
Advanced Configuration Options
The WLAN Utility also includes more advanced configuration
options for users in certain network environments. These options
include Power Management, RTS/CTS, and Fragmentation
Threshold.
Navigate back to the Configuration tab and then click the
Advance button to display the Advanced Configuration dialog
box.
26 ZoomAir USB Client Installation Guide & Reference Manual
Power Management—The Power Save option is designed to
conserve your computer’s battery life. If you click the Power Save,
your wireless LAN Card will go into sleep mode, minimizing power
consumption.
Note:
If you enable power saving, the Access Points you use
need to support power saving as well—otherwise
communication cannot be established.
RTS Threshold—RTS Threshold is intended to prevent the
problem of “Hidden Nodes.” Hidden Nodes involve two stations
that are within range of the same Access Point, but are not within
range of each other—they cannot hear each other. When one
station begins transmitting data via the Access Point, it might not
notice that the other station is already active. When these two
stations send data at the same time, they may collide when arriving
at the Access Point. Such collisions result in a loss of messages for
both stations.
Click Enable to use RTS Threshold on a suspect hidden station.
The station and its Access Point will then 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 data.
On receipt, the Access Point responds with a CTS message to all
stations within range, notifying them to defer transmission.
Chapter 4 Advanced Features 27
Note:
There is an implicit tradeoff when enabling RTS
Threshold. It could cause redundant network overhead
that could negatively affect throughput, instead of
providing a remedy.
Be sure to also specify the packet size. The RTS
mechanism will be activated if the data size exceeds the
value you set.
Frag. Threshold—Enabling Fragmentation Threshold improves
efficiency when high traffic is flowing along the wireless network.
If your USB Client often transmits large files and you enable Frag.
Threshold, the mechanism will split the packet. Value can be set
from 256 to 1500.
Status
The bottom half of the Configuration dialog box contains information about the status of your wireless connection. The following table defines this information.
State—
this field shows the MAC address of the Access Point that the USB
Client is communicating with. When the USB Client is operating in
AdHoc mode, it shows the virtual MAC address used by
computers participating in the AdHoc network.
When the USB Client is operating in Infrastructure mode,
Current Channel—Shows the channel on which the connection is
made.
Current Tx Rate—Shows the highest transmit rate of the current
association.
28 ZoomAir USB Client Installation Guide & Reference Manual
Throughput—
Shows the short term transmit and receive
throughput in bytes/second, and is continuously updated.
Link Quality—Based on the quality of the received signal of the
Access Point beacon. There are four states of link quality:
100%-80% Excellent
80%-60% Good
60%-30% Fair
Under 30% Poor or no connection
Signal Strength—Based on the received signal strength
measurement of the baseband processor of the Beacon signal.
Same as link quality, there are four states of signal strength:
100%-80% Excellent
80%-60% Good
60%-30% Fair signal strength
Under 30% Poor or no signal strength
You can click the Rescan button to force the radio to rescan all
available channels. If your link quality or signal strength is poor,
rescanning can be used to push the radio off a weak Access Point
and search for a better link with another Access Point.
Loop Back
The Loop Back dialog box helps you examine data transmission
quality between your USB Client and any workstation on the
network. Enter the IP address of one local client and one remote
client, adjust the Ping Interval and Packet Size (if necessary), and
click Ping. If there is a reply, communication is successful.
In addition, you can run a proprietary loopback test by clicking the
Loop Back button; this will verify the communication quality
between your wireless client and Access Point. Click the Refresh
button to set the counters back to 0.
Chapter 4 Advanced Features 29
AP Browser
If you click the Rescan button, the AP Browser displays all
Access Points in the vicinity. Besides listing the ESS ID of each
Access Point, the AP Browser box displays BSS ID, Channel,
Signal, Quality and Supported Rates. It also indicates if WEP is
enabled.
To join any of the displayed Access Points, highlight the Access
Point you desire to connect with and click the Join ESS button to
join the group. Note: Click Join BSS when there are more than
two Access Points with the same ESS ID.
30 ZoomAir USB Client Installation Guide & Reference Manual
Site Survey
By displaying the Site Survey dialog box, you can review the
channel quality of all 14 radio channels. A blue bar indicates that
channel quality is clear and good—the higher the blue bar, the
better the quality (i.e., less interference). A yellow bar indicates that
the channel quality is fair. A red bar indicates that a channel is busy
or experiencing severe interference.

Appendix A
Wireless Networking Overview
You can use the ZoomAir USB Client in two types of networks,
AdHoc (also called Peer-to-Peer) or Infrastructure. This
Appendix explains the basic difference between the two.
AdHoc vs. Infrastructure
A network is a group of individual computers called “clients”
connected together so that they can share information, an Internet
connection, printers, and other resources. A network can be wired,
wireless, or a combination of the two.
The simplest wireless network is called a “peer-to-peer “ or
“adhoc” network. In a peer-to-peer network, each client computer
communicates directly with every other client computer on the
network.
To set up a peer-to-peer network, all you need are two or more
computers equipped with wireless networking devices. The
downside of a peer-to-peer network is that the number of users
and the range are somewhat limited.

Laptop with PC Card
More complicated wireless networks, typically called
“infrastructure networks,” usually have an “Access Point” or
“Gateway” to manage the connections between computers in the
wireless network and other elements of the network.
In an infrastructure network, a wireless Gateway or Access Point
increases the range of the network and connects the wireless
network to a wired network.
