Click the red download (http://www.laptopvideo2go.com/forum/lofiversion/index.php/t7090.html) button at the top.

To update the driver, as there's no installer:
1. Right click on my computer.
2. Hit properties.
3. Hit the Hardware tab.
4. Hit device manager.
5. Right click on your Broadcom controller.
6. Hit properties.
7. Hit the Driver tab.
8. Hit update driver.
9. Hit next.
10. Hit "Display a list of the known drivers for this device..."
11. Hit Have Disk.
12. Select "BCM5750A1DDT.INF" from the directory you extracted the zip file to.
13. Finish the install process, then reboot.

I've attached two driver packages for the BCM57xx series.. Try "win_xp_2k3_32-8.48e.zip" first with the same procedure as I outlined above, and if that doesn't work, try the other.
