Re: DOT11_OPERATION_MODE_NETWORK_MONITOR in NDIS 6.0 on Vista

You should be able to use the "PCAGizmo" tool to examine OIDs above and below the Microsoft Native Wi-Fi driver. See the URL:

The call to set the operational mode NEVER makes it to the Atheros
driver. The call to read the mode does work and will return the
operational mode. Is Windows blocking the call down to the driver?
The Atheros driver has code to process the OID, but it never sees
it.
