Wireless adaptor has dissapeared on hp pavilion dv6000

A customer of mine brought an hp pavilion dv6000 laptop to me about a month ago that needed a motherboard replacement, and after replacing the motherboard everything worked fine, but now the WLAN has stopped working.  What is strange is that device manager does not even see a networking card. It is like it never had a card in it.
    The wireless switch is on but the light is orange like the switch is turned off.  This baffles me because even if the switch is off, shouldn't device manager still see a wireless card?

    Here is what I have tried so far:
    I installed a different card but vista did not recognize the change and device manager still does not see anything
    I reset the BIOS back to default settings
    I did a BIOS update
    I run sfc /scannow
         Vista reported that it found no issues
    I attempted to re-install the driver but that did no good either.
    I went into services and checked to make sure all services related to networking was running.  There is one service that is not running and will not start up.  It is "Internet connection sharing (ICS)."

    None of these steps have helped me.  I did some research on the internet and it seems a lot of people are having the same issue without an answer so a solution would sure be appreciated.

I hate to tell you this but the motherboard will have to be repaired or replaced again. It can be repaired by reflowing the chipset IC.
