I've been through the whole gamut of tablets and each one presented it's own problems with PXE booting and WinPE.
I'm now stuck on the new Dell Latitude 7350 with the Dell FM76N (which is a Realtek based USB3 --> Ethernet adapter).
Drivers have been added but it doesn't appear to work as expected.
Booting to WinPE and it doesn't pick up an IP address. I first assumed it was just a driver issue, but if I open a command window before it reboots I can unplug / replug the device and it immediately picks up an address!
So it's clearly not a driver issue related to the device, but maybe with the USB host?
Anybody encountered this before?
