Hi,
Do check if it's hidden or not in Device Manager.
- Open Device Manager and click on the View tab then put a check on Show Hidden Devices.
- If this doesn't work do try to install its driver using Intel's Support site.
- Here's the link: https://downloadcenter.intel.com/ (just use the automatic detect and install)
- If these doesn't work your last option is to perform a complete factory reset.
Hopefully this will help.
