All the drivers should come from cab file extracted into my documents folder.

You download the cab file

Then extract the cab file using 7zip after moving it to the my documents folder.

You can then update drivers offline instead of from the internet.

When you do that any feature updates do not need internet access when they update the machine.

No solution is in place.

Best we could do was to set Advanced Network settings to half duplex. Then it works ~75% of the boots. 

Hope it helps someone.
