This pop-up is generated by the Intel Remote Keyboard facility, which let's you control your NUC from w Smart Phone application. To disable this pop-up, you will need to go to the bottom right corner of your screen and check the System Tray for a Intel Remote Keyboard icon. Right click on it and choose Open. Once you have the app open, click on the Options tab and then click on the Disable Hosted Network radio button. Once you have this saved, you should no longer see this pop-up.
Hope this helps,
