LEDs
Your new C54RU has two LEDs on the antenna housing, so they can be seen when
the C54RU into a USB slot in your desktop computer.
The two LEDs operate in concert to inform you about the status and activity of your
C54RU.
When the two LEDs flash alternately, the C54RU is searching for a wireless network
connection − either to an Access Point or to another WLAN NIC.
When both LEDs flash in unison, there is a valid wireless network connection, and
there is activity over the link (data is being transferred). If the C54RU has
established a valid wireless network connection, but there is no activity, the two
LEDs will flash in unison, but much more dimly.
When the C54RU is disabled, only the Link LED flashes.
The following chart describes the full functions of the two LEDs.
The two LEDs are labeled Link and Act (Activity), as shown below.

First Time Setup − Windows 2000, 98, NT, and ME
Installing the drivers and WLAN utility
Before you start
• You will need a computer with an available USB slot to install your
C54RU.
• If you want to use the Wireless Encryption Protocol (WEP) to
authenticate access to your wireless network, you will need the WEP
keys that are in use for your network. WEP keys are generally entered
into a Wireless Access Point (AP) before configuring a wireless client
(such as a notebook/desktop PC with a C54RU installed).
• You should have a general idea of how your wired network (usually
referred to as a LAN) will provide a connection to the Internet
(sometimes called the WAN) and the point your C54RU will connect to
your LAN. In general, there are two methods to provide wireless access
to the LAN and then to the WAN − Infrastructure and Ad-hoc. Please
see the section titled Wireless Networking Basics, below.
You must install the provided drivers and
the WLAN utility for your C54RU before you
install the card itself.
Installation is a two-step process − firs
t
install the drivers and WLAN utility and
reboot your PC. Then install the C54RU in
an available slot. The drivers and WLAN
utility will then be automatically activated.
The installation software provided with your new C54RU
includes a Utility to configure and manage a WLAN link.
The WLAN utility is not required for Windows XP,
because Windows XP has WLAN support built-in.
The C54RU Driver and Utility Installation software will
install the WLAN utility software even if you have
Windows XP installed on your PC. You can choose to
use either the Windows XP built-in WLAN software or the
WLAN Utility software provided with your C54RU to
manage your WLAN link

Configuring your C54RU − Windows 2000, 98, ME, or NT
If you are using Windows 2000, 98, ME, or NT, the Configuration Utility program for
the C54RU is called Conceptronic 54Mbps Wireless Utility. Once you have installed
WLAN Utility (the configuration utility), you can read this section of the manual to
find out how to connect to a wireless network using WLAN Utility. Screenshots for
this section have been taken in Windows 2000.
To access WLAN Utility once it has been installed, just right-click on the WLAN
Monitor icon in the taskbar, as shown below.
The pop-up window shown below will appear. Click Wireless Network.
Alternatively, you can simply double-click the WLAN Utility icon in the task tray to
open the Conceptronic 54Mbps Wireless Utility, as shown below.
The field below the Available WLANs shows all of the Wireless Access Points that
your C54RU could detect. On your LAN, you will probably only see one AP, unless
you have installed more than one.

To connect to a particular WLAN AP, simply double-click its entry in the Available
WLANs field. Then enter WEP key.
This will open the Wireless Network Properties screen, as shown below.

The Wireless network name field must contain the SSID of the AP you are
configuring a connection for. This SSID is entered by default and in the case shown
above, is default.
Authentication Modes
There are four available types of user authentication supported by your C54RU −
Open System, Shared, WPA, and WPA-PSK. Authentication is a process very similar
to entering a username and password when you log on to your PC. It is intended to
prevent unauthorized people from accessing your WLAN network. You should
select the same Authentication mode here that you have selected for your WLAN
Access Point.
If you have enabled WEP on your AP, you can enable WEP on the C54RU and enter
the necessary wireless encryption keys on this screen. You will need to know the
length of the keys that will be entered. The drop-down menu allows you to specify
the key length from 64 bits (10 hexadecimal digits) − to 128 bits (16 ASCII
alphanumeric characters).
You must enter the encryption keys − including specifying the default key − exactly
as you entered them into your Access Point. If you have any difficultly making a
connection between your C54RU and your Access Point, disable WEP and verify that
the connection can be made without any encryption. Then re-enter the WEP keys
into your Access Point and your C54RU such that they are exactly the same.
If your WLAN network will not use the Infrastructure mode (using an Access Point),
but will use the peer-to-peer (Ad-hoc) mode, you can click the This is a computer
to computer (ad hoc) network; no access points are used click-box.
Setting the IP Address and Proxy Server
The C54RU’s WLAN Utility allows you to make IP address and proxy server settings
for each of the WLAN links you want to connect to. This allows you to have
multiple IP address and proxy server settings for multiple WLAN Access Points. For
example, if you have an Wireless Access Point at work, you will need one set of IP
address and proxy server settings to connect to your companies LAN. If you also
have a Wireless Access Point at home, you will need a different set of settings to
connect to that Access Point. For each of the WLAN links that are listed in the
Preferred WLANs field of the Configuration page, you can enter a different set of IP
address and proxy server settings. Each time that link is established, the settings
saved for use with that link will become active.
Enabling the Profile Settings
In order to make use of the IP address and proxy server settings for each WLAN link
you want to configure, you will need to enable this on the Options page. Clicking
the Option tab will open the following page.

Under the General Setting field, click the Enable IP Setting and Proxy Setting in
Profile click-box. This will allow you to use the IP address and proxy server
settings that are associated with each WLAN profile to be used. If this box is
unchecked, the IP address and proxy server settings made in the Windows
networking dialog boxes will be used. If you check this box, the IP address and
proxy server settings that were in use before (the Windows settings) will be saved.
The IP address and proxy server settings you entered for this WLAN profile will be
used for the connection. When you terminate the WLAN link, the saved IP address
and proxy server settings will be restored to their previous values.
Click the Apply button to make the settings current.
You can now make the IP address and proxy server settings required for each of the
WLAN links you want to make.
Click the Configuration tab to open the Configuration page. Select a WLAN link by
double-clicking the link in the Available WLANs field. This will open the Wireless
Network Properties page. Now click on the IP & Proxy Setting button to open the
following page.

If your WLAN AP for this WLAN link is configured to use the Dynamic Host
Configuration Protocol (DHCP) to assign IP addresses, subnet masks, default
gateway address, and DNS server address to PCs on your network, you can check
the Obtain an IP address automatically click-box. You can also click the Obtain
DNS server address automatically click-box.
Click on IP & Proxy Setting to set the IP address, Subnet mask, and Default
gateway manually instead of obtaining the IP address automatically through the
Dynamic Configuration Host Protocol (DCHP) server. You may also set the DNS
server address settings and WINS address settings.
If the network you are using is a computer-to-computer (or ad-hoc) network, no
access points are used. You may check the box This is a computer to computer
(ad-hoc) network; no access points are used to enable this option.
Using a Proxy Server
Some LAN networks will establish a proxy server to handle the downloading of web
pages, etc. and storing them temporarily so other users on the LAN can access
them without having to reload the web page from the Internet each time. This
allows for some saving of the available bandwidth in the connection between the
Internet (WAN) and the LAN.
