Hello, When I capture VLAN-tagged packets with wireshark, I don't see VLAN tags. My OS is Windows 7 and my ethernet card is TP-LINK TG-3468 (I installed the last driver and I disabled "VLAN & priority function" in the properies in the Ethernet card driver). With Unbuntu, I can see VLAN tags with wireshark. How can I do to capture VLAN tags ?

How can I do to capture VLAN tags ?

HINT: Are you sure the VLAN tagged frames are really sent to your system? Your switch might strip them due to its own configuration.

If you are sure about the switch: I suggest to boot the system with a Linux distribution (Ubuntu, Kali Linux) from a CDROM or a USB drive and capture the VLAN tagged traffic there, as your Windows driver might not support capturing of VLAN tags, as it seems to remove them in any case, regardless of config options you chose.

I'm sure there are VLAN because with Ubuntu, I can capture VLAN tags (to see my first message)

Ah, I did not see the comment about Ubuntu.

Well, then you already have a solution, right? ;-))

If it does not work on Windows, it's (most certainly) a driver problem and there is nothing the Wireshark community can do to change that. It's rather an issue for the TP-Link support.
