I have the same problem. "no" driver installed, no matter what i do on Windows 8.1 32 bit version
I am sorry for your issue.
May I ask for the wireless adapter model, BIOS and driver version you have installed?
Also, is there anything related to this device detected in BIOS? (Like 8086:0896 in Devices and Peripherals, PCI slots)
I updated BIOS to version 0025 from Download Center
Under Devices and Peripherals, PCI, Device ID I see "<8086:08B1>"
Not using any wireless adapter - I understand this NUC has built-in wireless which I'm trying to get to work.
