I have Windows 8 Pro workstation with Hyper-V installed and configured one virtual switch as "External", as on attached screenshot.

virtual switch configuration

My problem is, every time computer reboots, network does not work. "Diagnose" does not help, but disabling and then enabling of 'vEthernet (virtual-external)' network adapter solves the issue (until next reboot).

How to solve this permanently?
