I'm assuming that this is a driver issue, but I'm not sure how to resolve. The device cannot connect via wireless and cannot use Network Manager.

Thanks in advance!

I would use the latest version of Ubuntu with a new computer in order to get hardware drivers, that can recognize new hardware components. This was the case with my NUC6 when it was new. So I suggest that you try Ubuntu 17.10.1 and 'Bionic' that is still being developed and will be released next month (April 2018) as Ubuntu 18.04 LTS. You can find the developing release via the iso testing tracker at http://iso.qa.ubuntu.com/ — sudodus, Mar 07 '18 at 16:57
Unfortunately, this is a custom Lubuntu image. I would like to see if there are drivers to fix the issue before starting from scratch with a new OS. — user803236, Mar 07 '18 at 17:18
I don't know how to add drivers like that. Let us hope that someone who knows will see your question and help you. — sudodus, Mar 07 '18 at 17:21

The most hassle-free option will be to upgrade to Ubuntu 16.10 or later. If this is not an option for you, the following has been purported to work, but I can't personally speak to how well it works.

You will need to manually install firmware for the NUC7i3BNK, since it's not included in the Ubuntu 14.04 or 16.04 repositories. A guide for doing so can be found here: Ubuntu 16.04.2 on Intel NUC7i3, Bluetooth not working

Additionally, your kernel might not have drivers compiled in for that adapter. To fix this, you would have to recompile your kernel from source, which is a non-trivial undertaking, but also not too difficult, once you get the hang of it. (It's very CPU-intensive, and will take a few hours, most likely.) When you do the "xconfig" step, you'll need to locate the driver for your card and choose the option to compile it into the kernel. You can instead choose to compile the driver as a module, but then you'd have to load that module at boot by placing its name in /etc/modules. Unfortunately, I don't know what the name of that specific driver is, so you'll need to figure that out.

Here is a guide for recompiling your kernel: What's a simple way to recompile the kernel?

Good luck!
