I'm using an app from the google playstore, called "Wake On Lan" by Mike Webb.
On first use, the app scans for devices in your home, it finds your NUC (mac address and computer name) and then you add it to saved devices.
Works perfectly fine over wired and WiFi. The app can't wake my NUC that is completely shut down, where my IR remote control can .
In Windows I had to tick the checkbox where it says "Allow this device to wake the computer" check box in the properties of the WiFi adapter.
You have to find and check that setting in Ubuntu for yourself, it's probably similar to Windows.
My BIOS 42 settings are all default, untouched. Mine is a NUC6i5SYH.
My iPhone app would not work, but I just remembered that I have an android phone for testing purposes. I will install it and give it a shot. Ubuntu has a wake on lan config, but the setting is under the "wired" rather than wireless device. Hopefully the setting appears in just one location but will apply to the wireless too. I will update this later, after I give it a shot.
Did you solve the problem somehow? If not, allow me to try this configuration with a unit we have to see what will be the result.
That one instance occurred, right after I installed 16.04 LTS. There has been no repeated incident. It has been running flawlessly since I recovered it.
Bricked again this morning.
Has anyone been able to get a Wake On Lan app working with Ubuntu 16.04 WiFi -- wired ethernet has a wake on lan setting, wifi connections don't seem to expose it. Or have directions for pairing a TV Remote with the NUC using Ubuntu (but not Koid/XMBC).
