How to install W10 image from LAN?

We are trying to install W10 image from LAN, but can’t find any USB/lan adapters which are working on ubook.
We can use severel hundreds ubook’s, but only if we find an easy way to install the image.

Best regards

what is the problem with installing with usb flash?

I bought a generic USB to LAN adapter and it works just fine with my Ubook Pro.
