Hi:

That is not the id for the wifi.

That is the id for the wired ethernet controller.

If the wifi is missing a driver, you will see a device listed in the device manager as a network controller.

What is the full model number or product number of your CQ57?

The product number can be found on the same sticker as the serial number.

Install this software, restart the PC and see if you can turn the wireless on by using this software.

This package provides the HP Connection Manager for the supported notebook models and operating systems.

File name: sp54630.exe

If that doesn't work either, and you do not see a device listed in the device manager as a Network Controller, then most likely the wireless card has suffered a hardware failure.
