Hi all,

About 2 monthes ago, I can use capture filter to filter capture packets at my notebook( OS:windows 10). Recently, the capture filter can't work properly. when there is no filter conditions, it worked, but when it has capture filter conditions, it can't work with error message " unknown data link type -1"

Can tell me how to solve this problem? I had google it but no answer about it.

What interface are you attempting to capture on? Wireshark version? Post the contents of the Help -> About Wireshark -> Wireshark tab.
