Dell laptop running XP no longer sees wireless card

All of a sudden my Dell Latitude 610 laptop running XP SP3  32bit doesn't recognize the Broadcom
WLAN 1370 wireless card. It does not appear in the Network Connections window or in the
Device Manager, but the WiFi LED is lit near the power button.

Do you notice anything if you press Fn+F2?

This does nothing. Wifi LED remains lit.
Reinstall the driver.

I have done that several times. got them from dell for my service tag but no longer have dell support.
Removing the card and reinserting do anything?
From this website:

I think my  problem with the Intel 2915 wireless card not working may be related to the Texas Instruments PCI 6515 Cardbus that comes standard with Latitude D-610 machines. The driver for this is under the Dell drivers chipset category, but does not show up anywhere in the Device Manager listing after it's installed. When installing the Dell drivers as per the Dell instructions (see link below) I get two "Generic Cardbus Controllers" showing up under PCMCIA Apapeters category in the Device Manager listing (after the video driver is installed). These Generic Cardbus Controllers later disapper from the Device Manager listing when all the other drivers are installed.

Could a problem with the  Texas Instruments PCI 6515 Cardbus effect the internal Intel wireless Mini-PCI card and/or the external PCMCIA slot functionality?

Should the Texas Instruments PCI 6515 Cardbus driver show up in the Device Manager listing?

its laptop. How do I get to it to try that? Dell Latitude D610.
Also check if it is turned off in BIOS

Have you tested networking while in Safe Mode?  Does your wireless work?

removed card and replaced. balloon pops up on reboot seeing it but does not install anything and still doesn't show up Network Connections. Tried pulling card again, reboot, shutdown, then re-insert card. Again, balloon that sees it but nothing else. Will try safe mode when I get a chance.

Same thing in safe mode. Doesn't even know wireless card installed.

Tried all the MS steps at that link. Tried pulling the card again. Tried another brand wireless card and it worked. Think either the card is dead or XP SP3 conflicts.

Thanks to all for trying!
Could be either or both.

802.x cards do get warm and with extended use I've replaced several for clients so, that it is entirely possible it merely went bad.   And I've run into issues with some brands when SP3 came out, despite driver updates and such, so this could be the problem as well.

In any case, glad you have a solution and are running againg.   Thank you for keeping us updated.
