After waiting on the Dell Live-Chat queue for 40 minutes and some research by the Dell tech he determined that the following driver from Dell is the one I needed:  [URL] The big clue is that the BCM94318 is described as "Wireless 1370 WLAN MiniPCI Card".  Works great.  Hope this helps someone else. 
Latitude D400     Win XP sp3.  My wireless mini-pci card seems to have died.  To replace the original card I bought  a Broadcom BCM94318  (model WL5011s (TECOM) ) that was listed as compatible in a D400.  No drivers just  the hardware.   My machine recognizes that the card is physically there but I do not have a drivers for it.  Where can I get a driver that works?
