Thanks for joining the NUC community.
I understand you need to reconnect the USB 3.0 wifi adapter in order to detect it.
Please try updating to the latest USB 3.0 drivers; they are available at the link below:
Also, make sure you have loaded latest NUC BIOS here Intel® Download Center
File name: WYLPT10H.86A.0027.EB.EXE
Another thing VERY strange (I just verified it now). When I plug in the USB network adapter (and disable wireless in the NUC), all works great until I try to do a shutdown. When I do a Shutdown, the NUC powers down, then powers back up, the activity light on the external NIC blinks, then goes out. On inspecting in windows, the NIC is no longer listed. To get it back, I need to connect it to another port.
So there is TWO problems.
Shutdown turning into a RESTART
Disappearing USB device.
Thanks for the information.
Does it work when connecting on the back panel 2.0?
Is there any firmware update you can try on the Edimax AC-1200 USB 3.0 wireless adapter?
I have same NUC model and I have been able to power it down when I choose shut down. I am on 027 BIOS version. It does not seem to be a hardware problem, you may need to run system restore and restore your windows to an earlier time.
I was using back panel USB connections. Is there a difference in which USB connector is used (Back or Front, Top or Bottom, Left or Right?)
As for driver version, I have up to date driver from Edimax and NUC / Windows install is only about a week old. I use this NUC for software development, so I have a very limited set of software installed on it, almost all from Microsoft.
Thanks for the update, at this stage, it seems to be a problem with hardware compatibility. I recommend testing different USB 3.0 wifI adapter brands.
I regret to inform you that I do not have records of this part was tested with your NUC model
