Wireshark 4.0 and NPCAP 1.71 are not working for me - getting a disable promiscuous mode message. Tried disabling and packet capture still not functioning.
Wireshark 3.6.8 and NPCAP 1.60 work just fine with no errors.
Any thoughts?
This is probably due to 1) the Windows 11 driver for your adapter using the Windows NetAdapterCx framework, 2) the NetAdapterCx framework not strictly following the Network Driver Interface Specification (NDIS) rules, and 3) the Npcap driver expecting all adapter drivers to strictly follow that specification and reporting an error if they don't.
This should be fixed in Npcap 1.74, which was released today (2023-04-20). (The Npcap driver no longer reports an error for that particular violation of the specification; the 1.60 driver also didn't check for that particular violation.)
There is a current Wireshark issue open (18414: Version 4.0: failed to to set hardware filter to promiscuous mode) that points to a npcap issue: 628: failed to set hardware filter to promiscuous mode with Windows 11 related to Windows drivers with Windows 11.
And that Npcap issue appears to be fixed in Npcap 1.74, as per my comment.
