Thank you for contacting the Intel community.
In this case, we are not Linux*experts to help you with commands to work with Linux*on this NUC and also because Intel hasn't validated these operating systems. Intel® has validated only Windows® 10 for this unit as you can see here:
Supported Operating Systems for Intel® NUC Products
We recommend you use the latest kernel. If you need assistance with Linux* on Intel NUC, check your distro's website and forums for peer assistance or you can wait for another Linux* user to give you a recommendation with wireless connection on Linux*.

Which Ubuntu version is that because 16.10 uses 4.8.0 kernels?
Try download Ubuntu 17.04 iso and burn it on a DVD and boot from that (as livecd) - is the ethernet controller detected now?
If I recall it correctly a new Ubuntu version is released in the end of april (month 4 hence xx.04 in version) and in the end of october (month 10 hence xx.10 in the version) while new NUCs often hits the market in january or so.
Which gives (for example) that the 16.10 version might have some incorrect drivers for Intel NUCs arriving in january 2017 while Ubuntu 17.04 should have this sorted out (unless you want to use a ppa who contains backported/updated drivers like if you really want to stick to LTS (a new LTS (Long Term Support version) is scheduled for 18.04 that is in the end of april 2018)).
