(a) Profile Name
The first thing you will notice is the “Profile Name”. Initially this will say
“default” and be grayed out until you have set up a profile. Also, the
Profile
Manager Mode (k) will be “OFF”. Using Profiles allows you to save
configurations
for different wireless networks. For instance, if you use your Adapter at
your
place of work and also at your home, your wireless network settings
may be
different for each location. Profiles let you store settings for each
location and
name them for easy identification. The “default” profile will contain the
initial
configuration setting when you install the Adapter. To learn how to use
Profiles,
see the section of this manual called “Using Profile Manager Mode”.
(b) Operating Mode
Shows the current wireless mode the Adapter is operating in. There are
two
operating modes: “Infrastructure” and “802.11 Ad-Hoc”. Infrastructure is
the
most common mode to operate in and is the factory default setting. Use
Infrastructure mode when connecting your PC to a wireless access
point or to a
wireless router. Ad-Hoc mode is used to connect two or more
computers together
without the use of an access point or wireless router. To change the
mode, click
the down-facing arrow next to the Operating Mode field. Select the
mode you
wish to use, then click “Apply”.

(c) Channel
Shows the current channel the Adapter is operating on. When operating
in
Infrastructure mode, the channel is set automatically by the access point
or
wireless router that the Adapter is connected to. You cannot change the
channels in Infrastructure mode. In Ad-Hoc mode, the channel can be
set
manually. For more information about operating in Ad-Hoc mode, see
“Operating
in Ad-Hoc Mode”.
(d) SSID
The SSID is the wireless network name. This field shows the current
SSID with
which the Adapter is associated. The default (factory) setting is “ANY”,
which
will cause the Adapter to automatically look for any wireless network in
the area.
To connect to a specific wireless network, you can manually enter the
SSID of
the known wireless network. Note that the SSID is case-sensitive, so,
capital
letters do make a difference. To change the SSID, click in the SSID field,
type the
SSID you want, then click “Apply”.

(e) Tx Rate
Displays the current rate of data transmission. There are five Tx rates
possible:
Fixed 11Mbps—Always transmit and receive at 11Mbps data rate
regardless of
signal quality.
Fixed 5.5Mbps—Always transmit and receive at 5.5Mbps data rate
regardless of
signal quality.
Fixed 2Mbps—Always transmit and receive at 2Mbps data rate
regardless of

signal quality.
Fixed 1Mbps—Always transmit and receive at 1Mbps data rate
regardless of
signal quality.
Auto—Adjust speed according to signal strength. This mode is the
recommended
setting. It will decrease the amount of transmit and receive errors by
reducing
the speed of transmission in favor of receiving error-free data. Note that
data
being sent at Fixed 11Mbps with low signal quality will not necessarily
get the
data to the computer faster. This is because when errors occur, the data
must be
resent. When the signal quality is low, the chances for errors to occur at
high
speeds are greatly increased. Sending the data at lower speeds when
the signal
quality is poor will reduce the chances of errors, and thus data will get to
the
computer in the shortest possible time.
(f) MAC Address
Shows the MAC address of the Wireless USB Network Adapter.
(g) Status
Displays the BSSID (in hexadecimal) of the access point with which the
Adapter
is associated. If you are connected to a network, the word “Associated”
followed
by a series of numbers (the MAC address of the access point) will be
displayed. If
the Adapter is scanning for a network, you will see the word “Scanning”.
(h) Signal Strength
Displays the strength of the wireless signal from 0 to 100%. The closer
to 100%,
the better the signal strength is. The closer you are to a wireless router
or access
point, the stronger the signal should be.

(i) Link Quality
Displays the quality of the wireless signal from 0 to 100%. The closer to
100%,
the better the link quality is. Link quality differs from signal strength by
measuring the actual quality of the signal. It is possible to have low
signal
strength and high link quality.
(j) Activate Profile Manager Mode
See the section called “Using Profile Manager Mode”.

The Encryption Tab
The “Encryption” tab is used to set up the wireless encryption settings.
There are two ways to set up the encryption settings of your Adapter:
“Create
with Passphrase” or “Manual Entry”. Select “64-bit” from the drop-down
menu.
You will notice when using 64-bit encryption that there are four keys
labeled

“Key 1” through “Key 4”. Only one key can be used at a time. For ease
of use,
the software can generate keys using a passphrase that you enter. This
passphrase can be easily distributed to other wireless-equipped
computer users
in your network. For instance, creating a key using the passphrase
“Passphrase”
generates four keys in 64-bit encryption mode and one key in 128-bit
encryption
mode. In this scenario, a user of a laptop needs only to enter the
passphrase
and the key number into the computer’s wireless management software
to be
able to communicate while using encryption. All computers on the
network must
use the same encryption rate, passphrase, and key. The passphrase
can be
changed as often as desired.

will generate four keys (d) if you
choose “64-bit” or one key if you
choose “128-bit”. The keys are
obscured for security reasons so they
cannot be read by another person.
4. You can now select which 64-bit key you want to use from the
“Default
Key ID” drop-down menu. Leave this set to “1” unless you have a
specific
reason to use another key. Click “Apply” for the changes to be saved.

The Advanced Tab
The settings on the “Advanced” tab
should be left as is unless there is a
specific reason to change them.
(a) Preamble Type
The preamble is a signal used to synchronize the timing between the
Adapter
and the access point. Some older wireless equipment may not be able
to work if
this setting is too short. Leaving this setting to “Auto” is the most
effective way
to ensure the Adapter will connect to any wireless network available.
(b) Fragmentation Threshold and RTS/CTS Threshold
These settings should be left at their default settings. If you are
experiencing
many data errors, you can change these settings, however, network
performance
will likely decrease.
(c) Power Save
Enabling “Power Save” will help reduce battery consumption on a laptop
by
turning the Adapter OFF after each data set is sent or received to or
