Hopefully you installed the chipset drivers before you tried to install any other device drivers.  The driver for your wireless adapter is probably the following:

My Dell Latitude C400 crashed last week due to virus infection.  I reinstalled window XP pro and everything worked except my WiFi card.  I took the laptop apart and the WLAN card is the truemobile 1350 Rev.1.0. Since my laptop worked with the card before the crash.  I know that they should be able to work together. 

 

Could anyone teach me how can I make them work together?  A greek told me that although Dell does not advertise the truemobile 1350 can offically work with C400, there is some some special driver / setting so that they can work together.  Can someone help.

The problem originally posted to start this thread has been solved.  If you want help with a new problem, start a new thread,  Thanks.
