I have a Intel® NUC Kit NUC5i3MYHE, When I read the I/O Specifications,
It show "Integrated Wireless‡
Wireless antennas pre-assembled", Our customer believe NUC Kit NUC5i3MYHE can be wi-fi access point( AP), I try to explain it does no working like that.! So I need a official statement from Intel, NUC Kit NUC5i3MYHE can not be a wi-fi access point .!
Just for your information, hotspot can be created on system runing Ubuntu O.S. as well. See here an example: http://learn.linksprite.com/project/create-wifi-hotspot-in-ubuntu-16-04-android-support
So the answer for your quastin is that your customer is right (i.e. NUC can be used as an Internet Access Point)
