Changing the Default WEP Encryption Key

While selecting a mode for your IG-4150 and customizing its
settings, you can change the default WEP Encryption Key to
maximize the security of your wireless network.

Note: The IG-4150 has 64-bit Encryption enabled by default.

Therefore, you must enable 64-bit Encryption on your
Wireless Client.

Communication on your network is possible only among wireless
computers and other devices using the same WEP Encryption Key
(this key must be enabled). You can check and/or change the
default WEP Encryption Key on your IG from a computer that
has a Wireless Client installed.

If you have a ZoomAir IG and Wireless Client, the default WEP
Encryption Key consists of the last five numbers of the ID number
of your IG, which is indicated on the bottom and back labels of the
IG unit (for example, if ID number = 01bc99 then default WEP
Encryption Key = 1bc99). You can change the five characters in
the WEP Encryption Key string on a ZoomAir IG to any other
characters by selecting the Custom configuration option as
described in the preceding sections (see Configuring Custom
Settings, starting on page 33).

The IG ID number is also the Network Name, which serves as the
SSID as well. You cannot change this value.

The ZoomAir IG-4150 always has 64-bit encryption enabled, and
you cannot disable this feature. Therefore, any Wireless Client with
which you want your IG to communicate also must use 64-bit
encryption.

Note: If you are not using a ZoomAir IG-4150 with a ZoomAir

USB Client-4115 or PC Card on your network, see the
following section and the WEP Booklet for information on
WEP interoperability. Otherwise, return to the Overview
Of Your Settings screen in the IG Setup Utility to finish
configuring the device.

last five of the six characters in the Network Name – indicated
on the back and bottom labels of the device).

2

Convert the IG WEP Encryption Key to Hex Keys, using the
ASCII-to-Hex Conversion Chart in the WEP Booklet.

3

Set the Client Hex Keys to match the default WEP Encryption
Key of the IG (consult the WEP Booklet).

4

Through the IG Utility on the Client, change the default WEP
Encryption Key of the IG.

5

Set the Client’s Hex Keys to match the new Key of the IG
(Consult the WEP Booklet)

Using the IG-4150

General Guidelines

When using your IG-4150, please follow the guidelines listed
below:

Safety Guidelines

Do not cover the unit or block the airflow to the unit. Keep the IG
away from excessive heat and humidity. Protect the unit from
vibration and dust. Always disconnect the IG power adapter before
cleaning.

Operation Guidelines

To maximize the wireless coverage, place the unit as centrally as
possible (depending on the wireless computer’s vicinity). See also

Wall-Mount the IG-4150 on page 52.

The IG unit can be cleaned with a soft tissue. To avoid damage, do
not use liquids like alcohol or acetone. Do not rinse the unit with
fluids.

The IG consumes very little power. In order to extend the life of
your IG it is better to leave the unit powered on.

Wall-Mount the IG-4150

If you want to mount the IG-4150 on the wall, proceed as follows:

1

Remove the cover.

2

Use a small screwdriver to open the three cover screw holes.

3

Decide where and how you want to place the IG (you may
consider mounting the unit upside down in an elevated
location to be able to see the LEDs).

4

Place the cover against the wall, and put three marks on the
wall to indicate the screw positions.

5

Use the screws and the plugs that came with your kit to fix the
cover to the wall.

6

Close the IG.

IG-4150 Buttons

The IG unit has two small buttons for troubleshooting purposes.

• Reset button

• Reload button

52 ZoomAir IG-4150 Installation Guide & Reference Manual

Remove the cover from the IG unit to have access to these
buttons.

Reset button

This button allows you to recover from a situation in which the IG
may be in a deadlock situation. Pressing the button is the same as
disconnecting the IG from the power supply source.

After the reset, the IG reverts to the previous configuration profile.

!

CAUTION: Pressing the reset button disables all network

communications for a few minutes.

Reload button

Use this button only when you are not able to connect to your IG;
for example, when you have forgotten the IG password or WEP
Encryption Key.

This button allows you to disable the WEP Encryption Key and
the password. It also resets the DHCP settings of the device. Thus,
you have temporary access to the IG without the correct password
and WEP Encryption Key.

Chapter 6 Using the IG-4150 53

! CAUTION: Pressing the Reload button changes the IG

settings. To prevent irreversible changes, you must
disable Encryption on your Wireless Client to access your
IG in this forced Reload mode

Follow this procedure to disable Encryption:

1

Use a small screwdriver to press the Reload button on your
IG. The top LED on the IG changes from green to orange.
This is the only LED that is lit in this mode.

2

Access the IG remotely through your Wireless Client by
clicking the ZoomAir Client Manager icon on the taskbar in
the lower right-hand corner of your desktop. The icon will be
grayed out because you have pressed the Reload button on
your IG.

.

3

From the Actions menu, select Add/Edit Configuration
Profile, click the Edit Profile button, and clear the Enable
Data Security checkbox. Click OK.

The Client Manager icon turns green again as a radio
connection is established between your IG and your Wireless
Client. You can now use the IG, bypassing the password and
the WEP Encryption Key. To avoid risk of intrusion, do not
leave your network without a WEP Encryption Key for long.
