I have several Latitude D620's & D630's.  This morning, one of the D630's (with a Broadcom wireless adapter) was working fine on WiFi.  This evening, Windows XP Pro SP3 Device Manager doesn't even show the adapter.  I rebooted.  Same thing.  I checked the BIOS (in case the 7-year old had done something).  Everything seemed to be in order.  Connecting an ethernet cable seems to work fine.  I attempted to re-install the driver but that failed saying that there were no wireless adapters detected.  I removed the adapter and put it in my D620 (which is using an Intel PROset wireless adapter).  I knew the drivers weren't loaded, I just wanted to see if Windows recognized it as a network adapter.  It did recognize it.  I move the Intel PROset to the problematic D630.  It was not recognized.  The other interesting thing here is the WiFi switch (on the left side of the laptop) and the WiFi light above the top-right of the keyboard.  The WiFi light is always on.  When I change the position of the switch, the small wireless antenna icon appears on the screen.  It doesn't matter whether I'm putting the switch in the ON or OFF position, the icon always displays the ON position (i.e. not with the red circle-slash covering the icon).  In any case, the WiFi light stays on.  Since I've determined that it's not the adapter, what could it be?  Given the behavior of the switch and light, could the problem be with the switch?  Thanks in advance for any assistance you can provide.
