Specifications
Conceptronic Wireless 54Mbps USB Adapter 
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 PC with a C54RU installed). 
•  Windows XP includes built-in WLAN support software. Your new C54RU 
is also supplied with a WLAN Utility. You can choose which method you 
would like to use to manage your WLAN link. If you choose to use the 
Windows XP built-in WLAN management software, you should uninstall 
the WLAN Utility provided with your C54RU. 
•  If you know you want to use the Windows XP built-in WLAN support 
software, do not install the WLAN Utility provided with your C54RU. Do 
this − start your PC, install the C54RU, allow the Windows Found new 
hardware wizard to locate the drivers for your C54RU (located on the 
provided install CD), as shown below. 
•  If you want to use the WLAN Utility provided with your C54RU, or you 
are not sure which software you want to use, follow the instructions for 
installing the driver and WLAN Utility given for Windows 2000 (and other 
Windows versions) given in the sections above. You will then need to 
review the section titled Enabling the C54RU WLAN Utility in Windows 
XP, below. 
•  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. 
Install the C54RU WLAN driver from the WLAN USB adapter Installation Disk (the 
WLAN Utility is not necessary for Windows XP). You can then begin the driver 
installation procedure.
