![]() ![]() The driver cannot send packets either on its own or through a call to its MiniportSendNetBufferLists function. If your application uses WinPcap (as does, for example, Wireshark), it can't put the driver into "network monitor" mode, as WinPcap currently doesn't support that (because its kernel driver doesn't support version 6 of the NDIS interface for network drivers), so drivers that follow Microsoft's recommendations won't allow you to put the interface into promiscuous mode.Īnd if it could put it into monitor mode, that might disable transmitting packets according to this Microsoft page on monitor mode, "While in NetMon mode, the miniport driver can only receive packets based on the current packet filter settings. ![]() It is required for debugging purposes with the Wireshark tool. When I followed this link ( ), I received nothing. This is Windows, and the adapter is a Wi-Fi adapter, and, according to this Microsoft documentation on 802.11 drivers on Windows, "It is only valid for the miniport driver to enable the NDIS_PACKET_TYPE_PROMISCUOUS, NDIS_PACKET_TYPE_802_11_PROMISCUOUS_MGMT, or NDIS_PACKET_TYPE_802_11_PROMISCUOUS_CTRL packet filters if the driver is operating in Network Monitor (NetMon) or Extensible Access Point (AP) modes." Promiscuous Mode is a setting in TwinCAT RT Ethernet adapters. 'Promiscuous Mode' in Wi-Fi terms (802.11) it's called 'monitor mode' and this needs to be changed manually to the adapter from 'Managed' to 'Monitor', (This depends if the chipset allows it - Not all Wi-Fi adapters allow it) not with Wireshark. I used the command (in Window PowerShell) 'Get-NetAdapter Format-List -Property PromiscuousMode' to check if the Promiscuous mode is on and I received all 'false'. If youre capturing on Wi-Fi, promiscuous mode might not do anything at all - youd need to capture in monitor mode, and set up Wireshark to be able to decrypt traffic if its a 'protected' network using WEP, WPA, WPA2, or WPA3. Instead, it's important to prioritize ethical behavior and respect the privacy and security of others. You might not be able to put that adapter into promiscuous mode. Answer: It's important to note that cracking a WiFi handshake without the owner's consent is illegal and can result in severe legal consequences. You may also have to somehow decrypt that traffic, which may be somewhere between 'difficult' and 'impossible'. ![]()
