Re: DOT11_OPERATION_MODE_NETWORK_MONITOR in NDIS 6.0 on Vista

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Which specific Atheros driver (I mean, supported chipset) are we talking
about?

Are you sure the calls actually get forwarded all the way down to the

actually deliver the "uncooked" 802.11 frames.

Hello Smart People,

In NDIS 6.0, Microsoft added an operational mode called
DOT11_OPERATION_MODE_NETWORK_MONITOR. It is designed to turn a 802.11
wireless adapter into a promiscuous capture card. In this mode you
can set filters to see all raw data and management packets, set
channel, set frequency, gather statistics, etc.

I interested in using these new features for the purpose of packet
analysis in a protocol analyzer. Can these new features be used on
Vista from within an NDIS protocol driver? It appears they may be
blocked by Windows when I have tried to set them from within a
protocol driver. I'm using a current Atheros NDIS 6.0 driver on Vista
and the calls never make it down to the miniport driver.

Is this by design to prevent 3rd party application developers from
using these new features, or I'm I missing something?

Thanks,

Todd Lange

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.
