Network Hardware User Manual

2. The computer does not recognize the C54U.

• Make sure that C54U is properly seated in the computer’s PCI slot.

• If Windows does not detect the hardware upon insertion of the

Adapter make sure to completely remove drivers that were

previously installed. To remove the drivers, do the following:

A. Under Tools> select Folder Options…> select View >

under Hidden files and folders > select Show hidden files

and folders.

B. Uncheck Hide extension for known file types > click on

Apply.

C. Search for the files PRISMA02.sys and C54UG02.inf.

Remove these files from the INF and SYSTEM32 (DRIVERS)

folders in the Windows directory. Note: in Windows XP

and Windows 2000 will rename netN3AB.inf that have not

received certification into oem.inf files (e.g., oem1.inf.)

Therefore, please also remove all oem*.inf and oem*.PNF

files in inf folder of WINNT.

3. C54U does not work properly after the driver is installed.

• Restart the computer. (In some cases, it will be necessary to

restart the computer after installing the drivers.)

• In Windows XP, go to Start>Control Panel>System>Hardware Tab>

click on the Device Manager Tab> click on Network Cards> double

click on Conceptronic Wireless 54Mbps USB Adapter > make sure

that “This device is working properly” is displayed under Device

Status under the General Tab.

• If the device is not working properly and a yellow exclamation mark

is displayed, then there is probably a resource conflict. In this case,

make sure the computer system has a free IRQ and if necessary,

uninstall the drivers, restart the system, and repeat the driver

installation procedure.
