Wireless Adapter trouble on compaq F572

Built in Wireless Adapter doesn’t work.

I have an HP Compaq Presario F500 Series computer. (F572US). I bought the computer in Aug. of 2007. The Wireless adapter has a light on the front that always was blue before when it worked, but now is just orange all the time for the past several weeks. Others have had this same problem. I wrote to HP tech support and they gave me advice to upgrade the BIOS to the newest version, update the wireless adapter drivers and reseat the adapter in the slot it fits inside the computer. I did all 3 of those steps but to no avail.

I’ve updated BIOS to version F.1F

It is running Windows Vista Home Premium

The processor is an AMD Athlon 64 X2 Dual Core Processor TK-53.

HP Wireless Assistant program doesn’t open – if it did it’d help with troubleshooting and figuring out what to do.

WLAN doesn’t show up in Device Manager under the Networking section.

When I opened up the laptop to reseat the wireless adapter I see the Wireless adapter has a part number: 441080-001

What should I try now???

Thanks ahead of time for any advice as to what to try.
