You can use the procedure shown on the Broadcom page to determine which manufacturer's chip is in the computer and then go to the site you need.
Another option is to purchase a USB wireless adapter and use that instead. It would come with the drivers you need and avoid any possible compatibility problems you might have with trying to use the integrated LAN. HP designed the computer intending it to be used with Vista. While the original manufacturer's drivers usually work, the computer maker doesn't guarantee their hardware will work properly with drivers not supplied by them.

If there is no new driver then go to the manufactureres website. All of the drivers are there. Find your computer and download the driver.
