I have came across this issue recently. When I try to install the driver for the network adapter it says "No Intel Adapters are present in this computer". And when I try to locate the Intel Adapter in the device manager I cannot find it. I have tried updating the BIOS to the latest version, also I have reinstalled Windows 10. Still I could not solve this issue. I do not think it is a hardware issue because when I plug in the ethernet cable the orange light starts blinking.
