Wireless not working after Vista Sp1 Update

After a recent update to service pack 1, our clients  Wireless no longer works. I have downloaded and installed the latest Bios and Wireless driver from HP's website. The wireless card is 4321AG 802.11a/b/g/draft-n Wi-Fi and the HP laptop model is Pavilion dv6449us.

Here is what Everest gives me:

Can you right click and delete the device, then reboot and let it detect it again and re-install that way?

If the drivers from their site do not work I would contact HP support to see if they have encountered this before.

Ok, I had already downloaded and installed the Wireless drivers with no luck, if nothing works soon, I will have to call HP.

Is the card visible in your BIOS?

I don't see the wireless card in the BIOS. There is no actual place for wireless settings, also i have replaced two mini-pci express wifi cards and neither worked.

Hmmm.  Yeah, I'm thinking a call to HP would be the next step since you've tried installing multiple NICs.

Known issue, it was out of warranty but they are going to replace the motherboard free of charge.
