Hi facsn,
Here are some recommendations:
1. Your wireless card could be detected as 'Other Device' or 'Unknown Device', please check if you can see any of this in device manager.
2. Install the driver for the wireless card. The driver is available for download here: Intel® Download Center. Please select the appropriate operating system.
You will need to install 2 softwares. See below:
a. WiFi Driver: Intel® PROSet/Wireless Software
b. Bluetooth® Driver: Intel® PROSet/Wireless Software for Bluetooth® technology
Hope this is helpful.
Regards,
Sandra
