CaptureSetup VLAN tags

These days, network adapter becomes more and more smart. It filters VLAN tags automatic, so you can not read this filed from packet filter such as Wireshark. If your network adapter is old or simple enough, you do not have to worry about this problem otherwise, you should add extra variable at your registries within your windows.For example, If you use Broadcom NIC, you need to do flowing steps below:
1.Find TxCoalescingTicks.
2.Add new string value which named PreserveVlanInfoInRxPacket and default value is 1.
3.Reboot.

FYI:
