Can you check if th wireless is being detected in Device Manager it may show as Unknown Device or Network Controller
also Check under Network Adapters if you have a Wireless device Detected there.
If you can't seem to find any. Possible that the wireless Device is disabled
Try entering BIOS
Tapping F2 or FN+F2 while powering up the unit.
Once Booted to BIOs
Go under Configurations and Check if the WIreless there is Enabled.
Once Enabled tap F10 to Save and Exit
Boot to Windows and download and install the Driver I provided for the Wireless
Let me know you findings,
