Hi, all.
I am a newbie to writing NDIS driver.
I have a WLAN device and i want to fetch the 802.11 packets.
Can i do it using WFP callout driver?
If not, how can i fetch it in XP and Vista ?

Thanks in Advance,
Regards.

Baker.

Do you need to see raw 802.11 packets or the one already converted to
Ethernet?

Do you need to alter the packet flow in some way - like dropping the
packets or updating them?

Hi, all.
I am a newbie to writing NDIS driver.
I have a WLAN device and i want to fetch the 802.11 packets.
Can i do it using WFP callout driver?
[PCAUSA] No. Only 802.3 packates in WFP.

If not, how can i fetch it in XP and Vista ?
[PCAUSA] On Vista you can use a NDIS 6 monitoring lighteweight filter.

The 802.11 packets are not accessible on XP unless you work with adapter vendor proprietary APIs.

Good luck,

Thank you, Maxim, and Thomas.

I want to drop or permit the 802.11 packets.
Is it impossible in XP ?

If you’re dealing with 802.11 packets already converted to Ethernet - possible.
PASSTHRU sample can be used as a skeleton.
