Using RFMON is quite tough on the card and the PC, because
every single packet will go up the stack. The better way to do it is
to use "scanning", that allow you to get the same information in a
much more efficient way and avoid to put the card in RFMON mode. By
the way, "scanning" is what WinXP implements.
For now, I've only defined the scanning API in the Wireless
Extensions and implemented it in the Orinoco driver (see my web
pages). I was planning to add it to the Aironet driver, but for now my
lack of time and the lack of feedback from the list has gotten in the
By the way, in theory while in RFMON mode, the iwspy support
should work. But, I've never tried it.

I need to understand what API you need to control the card and
select various monitor modes, and then I will atempt to code that in
Currently, none to the Orinoco driver has any API to enable
things similar to RFMON.

This is just a period. Things come and go...
