it does not connect to internet so I cannot download anything to it.
have you tried to update your drivers manually?
I read someone having the same issue, right out of the box.
I found that a Windows 10 clean installation did not have drivers available for the Skylake NUC ethernet or wifi. You need to go to another computer and download the drivers from the link mentioned in the previous post response, copy them onto a USB key, and then install them onto the NUC. While you are at it I recommend downloading the other drivers as well.
It is for this very reason I keep a couple of inexpensive USB wifi adapters handy. They're a type that installs with the default drivers for Windows 7 and above, so when I do a new build on a NUC, I use that to connect to the Internet and update the OS and drivers.
Now back to the original issue:
Look in Device Manager to see if the wifi card is detected and drivers are installed.
If it's detected but shows an exclamation, then you need to install drivers.
If it shows a red X, then it's bad. If it's not listed in Device Manager, then go into the bios to confirm it's enabled.
If it's enabled in the bios but still isn't detected in Windows, try creating a Linux live USB drive and booting from that. If you boot into Linux and it still doesn't show up, you may have a hardware issue.
More than likely it's simply that you need to install the driver for the wifi card.
thank you all. I installed the drivers off a usb from another oc and now it is working.
