...for your computer..See the link below:

If downloading, then reinstalling the driver at the link above doesn't fix the issue, try restarting the computer into Safe Mode, then go to Device Manager and UNINSTALL the Broadcom device (including any duplicates of the same device, if there are any), then restart the computer.. Vista should re-recognize the device and install it.. If need be, reinstall the drivers again after Vista re-recognizes it.

Hope this helps.
